I've recently had a student email about ten times regarding material completely independent of class. In fact, I don't even teach the student in one of my own classes. They just happen to know I like the topics they're interested in. I've been pretty direct in poking holes in their thinking and pointing out what I consider to be errors or lapses in understanding. At the same time, I couldn't be more impressed by the intellectual charge they bring to the conversations and the genuine, obvious passion displayed for testing out beliefs to see how they hold up. In order to not focus solely on breaking down their beliefs and understandings, I wrote them the email below. I feel it's probably good for any student to read. Teachers aren't all knowing and we rarely know much about what's important to the students themselves. They deserve to know that and be reminded as frequently as possible. We have to learn things just like them and that requires chasing down and tackling new knowledge and understanding actively and vigorously. Waiting for it in class is a non-starter. It may never come. Hi,

Good teachers don’t exist.
At least not in a meaningful way. This is largely semantic, but think about what would make a teacher a “good” teacher. How do you provide evidence that someone is a good teacher? One place to start would be with asking stakeholders. Which stakeholders matter in deciding it? School districts? Administration? Fellow teachers? Parents? Students? The teacher his or herself? All of the above? All of the above would be too high a standard as no one would be a good teacher if all the stakeholders had to agree completely. So perhaps some percentage of the stakeholders? Is a simple majority of 51% enough? What if 90% of the administration, fellow teachers, and parents believe a person is a good teacher, but zero percent of the students do? Does the teacher still count as a good teacher? What if 100% of the students feel someone is a good teacher, but none of the adult stakeholders do? This can get more complicated by a further step. What if all the stakeholders mentioned above agree someone is a good teacher using 51% as the percentage threshold in one location, but not another? If all stakeholders in a public, San Diego, suburban high school agree a person is a good teacher and he or she moves to a private, Beijing, urban high school and none of the stakeholders believe he or she is a good teacher, who is right? Is this another question of percentages? Do we need 51% of locales around the world to agree a person is a good teacher? The above is premised on stakeholders having some kind of final say, but is that reasonable? Perhaps total societal welfare is a better metric. What if all the stakeholders mentioned above believed a person was not a good teacher, but total welfare in society actually goes up because of the person’s teaching? This might be seen in an example where a teacher focuses on creativity and innovation to the detriment of time spent on the standard curriculum. Perhaps the teacher is even fired for neglecting pre-written standards regarding math and language, but winds up sparking the next Facebook or Apple CEO. Would that teacher be a good teacher even though no one else recognizes them as such and actually lays them off? All of the above conflicting goals and agendas makes it impossible to state categorically if a person is a good teacher. I have found that generally speaking, being a good teacher is simply a process of doing what one is told by administration while trying to make parents and students feel good. In terms of achieving a job description, that seems to work. Since that job description changes at each school, it looks different everywhere you go. Am I good teacher? I can’t tell you that. The strongest claim I can make is that I’ve never been fired or had any major problems. I don’t think my students hate me or my class, but maybe they’re just better poker players than I am. Some are definitely bored, but I would be too if I were forced to take an art class for example. It’s just not my cup of tea. To each their own. Can I teach a particular subject well, say math or economics? That depends too. If you are interested, then sure. If you aren’t, it probably doesn’t matter. That differs from tutoring where essentially every student is “interested” in that they personally pay me and take the time to show up and listen. In a room of students, that isn’t the case. Some will listen and want to learn, others will look like they are, but aren’t, and still others will actively disengage altogether. I have the impression that teachers tend to have an overinflated sense of themselves. I would argue there are very few good teachers, based on metrics that matter to me, but most teachers probably feel they are pretty good or above average. It’s the Lake Wobegon effect popping up. In reality, most teachers could be replaced by the average caring adult and not be missed at all. The marginal effect of any one teacher is almost zero. I’d say it’s much more important to weed out potential problems from teaching than anything else. It’s much clearer that we can have truly bad teachers, ones that damage and harm students either physically or emotionally. The marginal effect in those cases is very high and very negative. It’s much less clear going the other direction. So give me your thoughts. What makes a good teacher? Is it universalizable or always specifically context dependent? Is there any meaningful sense to the phrase? Above are six learning curves representing six hypothetical persons. You can see a variety of initial performance levels, going from 1 for Ty, Jill, and Bob at time 0, all the way up to 500 for May. You can also see a variety of ending performance levels, going from 33 at time 10 for Bob, all the way up to 1000 for May. All of the learning curves on the diagram above improve over time, as represented by increased performance over time and all have different rates of improvement over time. The question I want to answer is, “Can all students can learn?” It depends. In the above learning curves, all students show improvement. However, that means almost nothing given the different rates of improvement and absolute performance levels over different time periods. In fact, the idea that growth rates or proficiency levels (performance levels) tell us anything at all is patently absurd once the above curves sink in. Let’s start by measuring some growth rates. Bob (light blue curve) went from a performance level of 1 to a performance level of 33. Bob’s percentage change = (33-1/1) x 100 = 3200% We could also state that Bob is 33 times “better” at time 10 than he is at time 0. Either way, that’s a lot of improvement if we compare it to May (purple curve). May’s percentage change = (1000-500/500) x 100 = 100% We could also state that May is 2 times “better” than when she started. Clearly Bob has much more “growth” than May if we use simple percentage change formulas to find a growth rate. However, if we switch from growth rates to proficiency levels as measured by the absolute performance levels, we find that May is 30.3 times (1000/33) “better” than Bob. If we had a school initiative that made sure certain minimums were met, should it measure those minimums using growth rates or proficiency levels? If we set the minimums using growth rate targets at 500%, May (100%) is falling behind, but Bob (3200%) is doing great! He meets the minimum after time 1, whereas May never reaches the target. If we set minimums using proficiency levels and use a performance level of 400, then May (500) meets the target at time 0, while Bob (33) is still 377 points shy at time 10. If we look at the other people in the diagram above while using the same targets, either 500% growth or a 400 proficiency level, we run into similar problems. Tia never reaches the growth target, but does cross the 400 target by time 1. Ty crushes the growth target and also meets the proficiency target by time 2. Jon never reaches the growth target, but reaches the proficiency target after time 7. Jill meets the growth target easily, but takes until time 7 to reach the 400 proficiency target and we can easily imagine her curve never crossing the proficiency threshold by simply shifting it down a bit. The above presents serious problems for standards-based initiatives like the hypothetical one above. A number of students will be measured as falling behind depending on how we select our targets. Furthermore, even if we agree to the target, there is the pesky question of time allowed to meet it. If the target is set at a 400 proficiency level, but it is expected to be met by time 1, only Tia and May will reach it. If we allow until time 6, we can add Ty. If we extend it to time 7, we include Jill and Jon. Many schools, districts, and nations use metrics similar to the above for measuring student learning. The United States has No Child Left Behind, but is by no means the only one to measure student learning with some type of standards. It began under a proficiency model of measuring absolute performance, but has since begun shifting to growth models in several states. The OECD has PISA. The International Baccalaureate uses proficiency levels with its standards-based rubrics. It should be clear that both growth and proficiency metrics have inherent problems. The above is aimed at showing how absurd many student measurements of learning can be. Success and failure are totally dependent on the metrics we decide to use. That only becomes worse the more variables we measure. For example, let’s assume the above learning curves are for math. What happens when we add language and find students with language learning curves that don’t match their math learning curves. Perhaps, Bob and May are completely reversed and we find May with low absolute performance levels and Bob with high absolute performance levels. Do they both count as failing if we require a proficiency level of 400 for both math and language? I recently finished Why School?, by Will Richardson, who stated the following in his book’s final pages, I can’t wait 10 to 20 years. By that time, our kids will have long since graduated, and the story of what schools become will have already been written. I hope they are places where adults and children come together to learn about the world, places rich with technology that lets our kids dream big and create things to fuel those dreams. I hope schools will be places where learning is fun, where it’s not so much about competing against one another as about working together to solve the really big problems we’ll face together in the years ahead. (Kindle Locations 559-562) That seems right to me.
Let’s return to the initial question, “Can all students learn?” Of course, but what that means is up for debate. If it means hitting a particular standardized level of proficiency or growth, then no. Some students will never reach particular growth or performance levels selected for them. However, if, as Richardson writes elsewhere in his book, it means that students, "have the skills and dispositions they need to solve whatever hard problems come their way, and [that] they’ll know how to go about creating something of value and sharing it with the world,” then YES! (Kindle Locations 543-544).
Learning, education, and school are tricky. We definitely want more learning to happen, but figuring out what it should be and look like is harder. What We Want It to Do More learning is good for both society and the individual. From a societal standpoint, the reason we definitely want more learning is because it accounts for 70 to 80 percent of improved living standards over the last 200 years. That is according to Nobel Laureate Joseph Stiglitz who believes we should aim to create a “learning society” as a result. He explains, most of the increases in standards of living are a result of increases in productivity—learning how to do things better. And if it is true that productivity is the result of learning and that productivity increases (learning) are endogenous, then a focal point of policy ought to be increasing learning within the economy; that is, increasing the ability and the incentives to learn, and learning how to learn, and then closing the knowledge gaps that separate the most productive firms in the economy from the rest. Therefore, creating a learning society should be one of the major objectives of economic policy. If a learning society is created, a more productive economy will emerge and standards of living will increase. (Kindle Locations 313-318) Much of the learning Stiglitz discusses relates to “learning by doing” or on the job learning. He points out that the industrialization process itself is responsible for much of the “learning how to learn” that societies need. That makes it harder for nations to innovate when they skip over the industrialization process and go from agricultural to service economies. From an individual standpoint, psychology research has repeatedly included mastery, competence, and accomplishment as factors that consistently contribute to people’s happiness and drive. From this viewpoint, people have a natural tendency and joy to learn when not being coerced to do so and more learning therefore results in more overall peak experiences, or what psychologists call flow. Besides living in a richer society with happier people, we probably also hope that education decreases criminal behavior and increases overall health and longevity. We’ll see if any of these wishes are realized, but let’s first look at some costs of providing education. What It Costs Us Public education in the United States is expensive. According to the National Center for Education Statistics, “Total expenditures for public elementary and secondary schools in the United States amounted to $620 billion in 2012-13.” Looking at calendar year 2013-14, “postsecondary institutions in the United States spent approximately $517 billion (in current dollars). Total expenses were nearly $324 billion at public institutions, $173 billion at private nonprofit institutions, and $21 billion at private for-profit institutions.” If we only look at the public institution expenditures, then elementary through postsecondary institutions spent a total of $944 billion. The numbers for elementary/secondary and postsecondary are one year apart, but the general expenditures don’t swing wildly. The United States spends roughly a trillion dollars on education each year, equivalent to over five percent of total GDP. Using the same sources above, these numbers amount to $12,296 per public school student in elementary and secondary and $30,502 per public university student. These figures are roughly 30 and 80 percent higher than those of countries in the OECD. This shows these numbers are not just absolutely high, but also comparatively so. Imagine what a family could potentially do with that type of money each year if it was given directly to them by the government and not spent on their behalf. Two Theories of Education: Human Capital and Signalling There are two primary theories of the effects of education in economics, although some economists do have their own pet theories. The theories of human capital development or screening and signaling theory are summarized below, The relationship between education and earnings has long intrigued economists and in recent years two contrasting views have emerged. The theory of human capital holds that education directly augments individual productivity and, therefore, earnings (Schultz, 1961; Mincer, 1974; Becker, 1975). By forgoing current earnings and acquiring, or more precisely, investing in, education, individuals can improve the quality of their labour services in such a way as to raise their future market value. Human capital, according to this view, is akin to physical capital, the acquisition of which entails a present cost but a future benefit. Thus education may be regarded as an investment good, and should be acquired until the point at which the marginal productivity gain equals the marginal opportunity cost. Most people are shocked the first time they learn of the signalling theory of education and immediately dismiss it as ridiculous. How could it be possible that school doesn’t develop human capital in some capacity? Instead of rejecting it out of hand, keep an open mind as some evidence is presented below. Behavioral Genetics, or a Look at Twin Studies Bryan Caplan has written a couple fantastic books, but the one that concerns us here was an attempt to summarize the state of knowledge as gleaned from twin studies. His point was to emphasize that parents should chill out regarding their self-induced stress over parenting, but the information could just as easily be applied to education and students; it had little to do with parenting per se and more to do with the effects of genetics and environment on life outcomes. He makes sure to state a clear caveat, What you find depends on where you look. Almost all twin and adoption studies are set in developed countries. Families that adopt are usually middle class, and always want children. It would be irresponsible to read these studies, then tell the world that child abuse does no lasting damage or that your child will turn out equally well if he grows up in the Third World. (p. 165) I’ve summarized his points below. Caplan writes that, Environment has an effect on:
Environment doesn’t affect:
Environment has little or no effect on:
As one can see, environment has zero to little effect on many of the things we find most important, including income, happiness, criminal behavior, and health. As “school” is a part of the environment, we really would hope for the opposite of these findings if we want to endorse the human capital model of education explained above. Let’s look a bit closer at a few of these points. Income According to economist Branko Milanovic, we also know, a person’s income in the world [can be explained] by only two factors, both of which are given at birth: his citizenship and the income class of his parents. These two factors explain more than 80 percent of a person’s income. The remaining 20 percent or less is therefore due to other factors over which individuals have no control (gender, age, race, luck) and to the factors over which they do have control (effort or hard work). So learning is important for innovation, which increases living standards as noted by Stiglitz above, but income is mostly accounted for by geographical location and parents’ income class, with very little left over for one’s personal effort, in school or otherwise. In addition, Bryan Caplan elaborates that, Yes, wealth and poverty run in families. According to twin and adoption studies, however, the main reason is not upbringing, but heredity. Nurture has even less effect on income than on education. None of the above is good if we are hoping for education and school to have large impacts on incomes. It gets even worse for the education optimists though, Dale and Krueger concluded that students, who were accepted into elite schools, but went to less selective institutions, earned salaries just as high as Ivy League grads. For instance, if a teenager gained entry to Harvard, but ended up attending Penn State, his or her salary prospects would be the same. It therefore seems that specific colleges aren’t doing much in particular to increase incomes for people, something both Milanovic and Caplan would have assumed. Instead, it is likely that general intelligence as estimated by the SAT and the ability to be selected in the first place is what matters. This would give credence to the idea that schooling is simply a screening and signalling device for talent and other socially desirable characteristics like conformity. Intelligence Perhaps rather than increasing income, school increases intelligence. We saw from Caplan’s list above that environment had zero effect on IQ. Again, this seems very counterintuitive for most. What can we find if we look? If we take a look at critical thinking, reasoning, and communication as skills that would assumably help future citizens deliberate and decide, we find that, Richard Arum and Josipa Roksa reported that most students didn't improve after four years of college, and a full third didn't improve at all. Now they've written a follow-up, which concludes, unsurprisingly, that students with high Collegiate Learning Assessment (CLA) scores do better in the job market than students with low scores. This means that students with better thinking and reasoning scores on the CLA do better in the job market, but that those abilities are hardly or not at all improved after four years of college. To help explain intelligence, Daniel Willingham writes in The Atlantic, Intelligence has two components. One is akin to mental horsepower—how many pieces of information a person can keep in mind simultaneously, and how efficiently that person can use it. Researchers measure this component with simple tasks like comparing the lengths of two lines as quickly as possible, or reciting a list of digits backwards. The other component of intelligence is like a database: It entails the facts someone knows and the skills he or she has acquired—skills like reading and calculating. That’s measured with tests of vocabulary and world knowledge. The above may tempt us to infer that while we don’t seem to be very good at teaching critical thinking or increasing mental horsepower, content matters enough for increasing intelligence that we should focus even more on the content we deliver. That’s not the right conclusion, though. Knowing more is good, but facts don’t have to come from teachers and many of the facts that do aren’t remembered. All of this fits with findings on expertise, where factual knowledge is known to be the bottleneck. Daniel Willingham also tells us that retention of content is also quite low, leveling off around 30 percent of content learned in class for A students and around 20 percent of content for B students. In Why Don’t Students Like School? he writes, In one study, researchers tracked down students who had taken a one-semester, college-level course in developmental psychology between three and sixteen years earlier. The students took a test on the course material. Figure 5 shows the results, graphed separately for students who initially got an A in the course and students who got a B or lower. Overall, retention was not terrific. Just three years after the course, students remembered half or less of what they learned, and that percentage dropped until year seven, when it leveled off. The A students remembered more overall, which is not that surprising—they knew more to start with. But they forgot just like the other students did, and at the same rate. (Kindle Locations 1955-1961) If most of the content teachers are delivering is forgotten, where should students get their knowledge? Sugata Mitra’s research informs us that kids can learn quite a bit on their own when given access to a computer and the internet. He writes, When working in groups, children do not need to be "taught" how to use computers. They can teach themselves. Their ability to do so seems to be independent of educational background, literacy level, social or economic status, ethnicity and place of origin, gender, geographic location (i.e., city, town or village), or intelligence. In addition, Stephen Krashen’s research on language acquisition and literacy shows that those that read more:
The “more reading” Krashen refers to is “free voluntary reading” where students can select their own texts and difficulty level freely. He also states that results do not improve if teachers use rewards, lexiles, error correction, or supplement with writing, although less writing apprehension is experienced by the free voluntary readers. Finally, he also notes that surfing the internet can increase reading and that greater access to books of all types does so as well. Many of these findings helped me explain why reading 100 books in a year was the fastest and most effective way for me to learn more than any other period in my own life. Learning Transfer The reason most teachers attempt to handpick and deliver content is the hope of learning transfer. It is somewhat the holy grail of school. However, learning transfer is hard and not very reliable. Furthermore, we don’t know what content will be particularly useful in the future as technologies change and some jobs disappear, while entirely new ones appear. According to the Committee on Developments in the Science of Learning, the ultimate goal of schooling is to help students transfer what they have learned in school to everyday settings of home, community, and workplace. Since transfer between tasks is a function of the similarity by transfer tasks and learning experiences, an important strategy for enhancing transfer from schools to other settings may be to better understand the nonschool environments in which students must function. Since these environments change rapidly, it is also important to explore ways to help students develop the characteristics of adaptive expertise. (p. 73) When research is conducted on actual transfer of learning, David Perkins summarizes, a superficial look at how research on transfer casts its vote is discouraging. The preponderance of studies suggest that transfer comes hard. However, a closer examination of the conditions under which transfer does and does not occur and the mechanisms at work presents a more positive picture. (p. 10) Perkins also writes, In many situations, transfer will indeed take care of itself - situations where the conditions of reflexive transfer are met more or less automatically. For example, instruction in reading normally involves extensive practice with diverse materials to the point of considerable automaticity. Moreover, when students face occasions of reading outside of school - newspapers, books, assembly directions, and so on - the printed page provides a blatant stimulus to evoke reading skills. This description sounds much closer to the type of learning that Stiglitz and other economists have in mind when talking about increased productivity via learning by doing. “Hugging” could be summarized as learning by doing the thing you want to get better at, while “bridging” could then be thought of as actively reflecting and seeking out ways to improve that thing. A teacher would then be acting as a coach and the model would look nearly identical to that of deliberate practice within the field of expertise studies. Teacher Effects We know from John Hattie that almost anything a teacher does “works” for enhancing academic “achievement”, which is another way of saying student grades. He then moves on to make the further point that since everything works for enhancing achievement, asking what works is the wrong question. We should then ask about what works more than the average intervention. Hattie measures interventions using effect sizes and finds that 0.4 is the average effect size in educational settings and encourages schools and teachers to then focus on effect sizes greater than this, which he kindly lists based on his research. To give the reader an idea of the educational influences with the largest effect sizes, the top 30 as of 2015 are:
Don’t worry too much about what all the influences mean. It’s not always clear that some of these influences are causal in any way and critiques of Hattie’s entire method have been made. However, what I’d like to point out by referring to the bolded items in the list above is that many of the strongest influences on achievement overlap greatly with the ideas mentioned in the section on intelligence and transfer of learning. We want students spending a lot of time doing the thing they want to get better at with feedback and assessment from clear teacher instructions, much like coaches in the deliberate practice model or hugging and bridging from Perkins recommendations for transfer. These ideas seem routine, but they’re also somewhat of a tacit admittance that teachers can’t really force change. In fact, some of the most progressive learning theories are those of constructivism, which all but admit that students must learn for themselves and cannot be “taught” in the traditional sense. These are strange angles to approach school from in its traditional role as developer of human capital or increaser of student ability. GPA and Tests So we do have some sense of what is important if our goal is to increase grades, but that doesn’t necessarily mean that grades predict anything of value or matter for long-run life outcomes such as happiness, income, and health. As we’ll see below, it is not obvious that grades tell us much of anything about a person’s future prospects and life outcomes. While all of the effect sizes mentioned by Hattie are essentially measurements related to grades, it is important to keep grades in their proper place. In an interview with Laszlo Bock, senior vice president of people operations at Google, Adam Bryant reports, One of the things we’ve seen from all our data crunching is that G.P.A.’s are worthless as a criteria for hiring, and test scores are worthless — no correlation at all except for brand-new college grads, where there’s a slight correlation. Google famously used to ask everyone for a transcript and G.P.A.’s and test scores, but we don’t anymore, unless you’re just a few years out of school. We found that they don’t predict anything. So even if we sort of know what works for increasing GPAs and test scores when looking at research, employers are finding those numbers less and less relevant. Conclusion School doesn’t do much. It doesn’t increase income. It doesn’t increase intelligence. The content it does deliver is mostly forgotten. Most of it could be learned independently anyhow. School may be entirely signalling. Teachers can affect achievement as measured by grades with the biggest effects coming from a coaching, deliberate practice type model. However, grades aren’t too important as employers are becoming more and more aware that they have no predictive ability for job performance and students can always opt to go the community college route without stressing over them. So how should we think about all of this? For now, I think it’s best to relax and lighten up about school and grades. Learn for learning’s sake. It makes you happier as stated at the beginning of this article, and if you have the talent and drive to learn at the cutting edge of STEM fields, you can also make the world better through your innovations. If you don’t quite have those abilities, perhaps Charles Murray’s ending paragraph from Real Education can help redefine aims, Educational success needs to be redefined accordingly. The goal of education is to bring children into adulthood having discovered things they enjoy doing and doing them at the outermost limits of their potential. The goal applies equally to every child, across the entire range of every ability. There are no first-class and second-class ways to enjoy the exercise of our realized capacities. It is a quintessentially human satisfaction, and its universality can connect us all. Opening the door to that satisfaction is what real education does. (Kindle Locations 2095-2099) Perhaps more than anything else, we should think really hard about the expenditures per pupil summarized above. What are we getting for $12,296 per public school student in elementary and secondary? Would that money be better utilized if simply given to students to do as they wished as a sort of universal basic income for minors? Would we get all the same results if we made use of credentials, certifications, and online curricula instead of diplomas? Would the money be better spent entirely focused on preventive health in order to make a sizeable dent in the chronic diseases that make up roughly 85 percent of the $3 trillion spent on healthcare each year? These questions are difficult, but looking at the evidence is important if we wish to begin answering them with the hope of improvement.
I’ve recently learned a new phrase, "moral narcissism", from Arnold Kling, who seems to have gotten it from Roger Simon. It’s explained as such, If your intentions are good, if they conform to the general received values of your friends, family, and co-workers, what a person of your class and social milieu is supposed to think, everything is fine. You are that “good” person. You are ratified. You can do anything you wish. It doesn’t matter in the slightest what the results of those ideas and beliefs are, or how society, the country, and in some cases, the world suffers from them. It doesn’t matter that they misfire completely, cause terror attacks, illness, death, riots in the inner city, or national bankruptcy. You will be applauded and approved of. After reading the above, I happened to notice several memes on Facebook within a couple days. They are the three featured in this post, one above and the two below. I have no issue with any of these memes or the teachers that liked or shared them on Facebook. One of them was from my wife! I know the "intentions were good" and that "they conform to the general received values of friends, family, and co-workers, and what a person of their class and social milieu is supposed to think". To be totally clear, I agree with all three. However, the same article referenced above went on to point out that, Moral narcissism is the ultimate “Get out of jail free” card in a real-life Monopoly game. No matter what you do, if you have the right opinions, if you say the right things to the right people, you’re exempt from punishment. People will remember your pronouncements, not your actions. And that is the problem. These memes allow us teachers to "get out of jail free". We (mostly) all buy into the idea that school does "produce people who are unable to distinguish what is worth reading", that we should "never limit questions", and that there is a major difference between the "learner and learning".
However, by simply pronouncing those beliefs and getting a pat on the back from fellow teachers and educators, we don't have to do the hard work of taking action and suffering the possible consequences. We aren't punished or held accountable by each other when we don't produce critical thinkers able to distinguish what is valuable and important. We aren't punished or held accountable by each other when we do limit questions and curiosity because we need to stay on track with the mandated curriculum or we won't finish in time. We aren't punished or held accountable by each other when we do focus on the "learning" and not the fact that the student isn't interested, is stressed, or really does want to walk down a different path entirely besides the societally approved high school, college, job, marriage, house route of success. Teachers are great people. They work hard. They care. They want the best for their students. None of that necessarily implies they do what is needed for the students to lead rich, fulfilled lives both today and in the future. Teachers must change. Perhaps we can start by recognizing our own collective moral narcissism. Many people are concerned with the development of superintelligent AI. Elon Musk above is one of them. These concerns have been laid out in great detail by Nick Bostrom in his book Superintelligence. I highly recommend it. Sam Harris has also given a great TED Talk on the reasons for concern. Every concern I’ve seen stated to date is a concern for humanity’s sake. All are worried about the threat to our existence that AI poses and the suffering that could result is very real. I hear those concerns and take them as genuine and something we should all be thinking hard about. Harris’ video above makes that point clearly. I think there is another reason to be concerned though and that is for the ethical dilemma the creation of superintelligent AI creates in relation to the potential suffering of the AI itself. This concern follows directly from rejectionism and the set up to understand it is eloquently explained by Coates, Humans suffer more than other animals for a number of reasons. Animals have few needs and when these are met they are contented. Moreover they live in the present and have no sense of time - no sense of the past or the future and above all no anticipation of death. Not so with man. First, our desires and wants are far greater and therefore our disappointments are keener. Whilst we are capable of enjoying many more pleasures than the animals – ranging from simple conversation and laughter to refined aesthetic pleasures - we are also far more sensitive to pain. We not only suffer life’s evils but unlike animals are conscious of them as such and suffer doubly on that account. Most importantly perhaps it is our consciousness of temporality that makes us suffer the anxieties and fears of accidents, illnesses and the knowledge of our eventual decay and death. The idea of our disappearance from the world as unique individuals is a matter of great anguish and makes us look for all kinds of means of ‘ensuring’ our immortality. In the main it is religious beliefs that cater to this need. As a professed atheist Schopenhauer finds these and many other aspects of religion as mere fables and fairy tales , a means of escaping the truth about existence including our utter annihilation as individuals by death. If superintelligent AI could become even more sensitive to pain than any human currently is, and there is no reason to suspect it couldn't, then the above should worry us.
Imagine an AI that becomes more aware of pain and suffering than any human in the same way we are relative to dogs, or mice, or ants. Then imagine it having access to the internet, satellites, and all other digital devices. It would “see” suffering at an unimaginable scale. Every email, chat, text, image, video, personal notes and documents on the cloud. All would be open to such an AI. The amount of suffering that would rush in all at once would be overwhelming. I pity any AI that awakes to such a reality. So in the same sense that procreation of other humans is wrong on rejectionist principles, the creation of a superintelligent, conscious AI would be even more wrong and should also not be brought into existence. Rather than the AI becoming a utility monster that destroys us for its own benefit, it could just as easily become an entity of immense suffering that would make the Passion of Jesus seem as child’s play. Of course, I hope that AI doesn't destroy us or suffer if and when it is created, but the possibility that it may suffer infinitely more than any and all humans combined provides yet another reason to have serious worries over its creation. Q. What is Rejectionism? The above comes from Anti-Natalism by Ken Coates. It’s a wonderful little book written to explain the philosophical viewpoint of rejectionism by situating it in its historical religious, philosophical, and literary contexts. It’s also worth pointing out his second point completely overlaps with current understanding from modern physics and biochemistry. Life is just self-sustained replication with the help of added resources. In fact, Kurt Gray writes in Know This, The MIT physicist Jeremy England has suggested that life is merely an inevitable consequence of thermodynamics. He argues that living systems are the best way of dissipating energy from an external source: Bacteria, beetles, and humans are the most efficient way to use up sunlight. According to England, the process of entropy means that molecules that sit long enough under a heat lamp will eventually structure themselves to metabolize, move, and self-replicate— i.e., become alive. Granted, this process might take billions of years, but in this view living creatures are little different from other physical structures that move and replicate with the addition of energy, such as vortices in flowing water (driven by gravity) and sand dunes in the desert (driven by wind). England’s theory not only blurs the line between the living and the nonliving but also further undermines the specialness of humanity. It suggests that what humans are especially good at is nothing more than using up energy (something we seem to do with great gusto)— a kind of specialness that hardly lifts our hearts. (Kindle Locations 269-276) Back to rejectionism. Coates continues, Q. What are the core values of rejectionism? Christine Overall echos the above sentiments in her book Why Have Children?: The Ethical Debate when she writes, “The so-called burden of proof—or what I would call the burden of justification—should rest primarily on those who choose to have children,” (Kindle Locations 225-226). Overall goes on to clarify, The questions we should ask are whether such a desire [to procreate] is either immune to or incapable of analysis and why this desire, unlike virtually all others, should not be subject to ethical assessment. There are many urges apparently arising from our biological nature that we nonetheless should choose not to act upon or at least to be very careful about acting upon. Even if Aarssen is correct in postulating a “parenting drive,” such a drive would not be an adequate reason for the choice to have a child. Naturalness alone is not a justification for action, for it is still reasonable justification for action, for it is still reasonable to ask whether human beings should give in to their supposed “parenting drive” or resist it. Moreover, the alleged naturalness of the biological clock is belied by those growing numbers of women who apparently do not experience it or do not experience it strongly enough to act upon it. As Leta S. Hollingworth wisely noted almost a century ago, “There could be no better proof of the insufficiency of maternal instinct as a guaranty of population than the drastic laws which we have against birth control, abortion, infanticide, and infant desertion.” (Kindle Locations 241-249) This starting point is important. It already takes us far beyond the normal line of thinking which takes life for granted and gives no second thought to it. But what if life isn’t good? What if it shouldn’t be perpetuated? Naturally, this viewpoint can be jarring. It conflicts with our instincts and drives. That’s the whole reason it needs to be laid out carefully. It doesn’t “feel” right. That’s largely a byproduct of our evolved psychology and we shouldn’t let it mislead us. This is why Coates explicitly states, “It follows that to endorse existence is to condone evil, indeed to invite evil, albeit unintentionally. It follows that those who support and endorse existence are responsible, even if indirectly, for the crimes of humanity” (Kindle Locations 2020-2021). In this view, “acceptance” is an endorsement of evil and “rejection” is a compassionate act undertaken to avoid needless suffering. Given the above, the well-lived life entails rejecting existence as good, not procreating, and supporting philosophical anti-natalism. Because this worldview is so contrarian, the most good one could do in terms of alleviating suffering is to simply spread these ideas. In that sense, it is an optimistic worldview in that it does aim for a better world, although not quite the one most imagine. The vast majority of people will not agree and so a sea change of needs to occur. Some of the people I currently admire the most do not question existence at all and often state a tacit or explicit endorsement of “acceptance”. This troubles me because I respect them greatly, find them extremely intelligent, rational, curious, and scientifically oriented. If even these people endorse acceptance by default, it will be a very long road to a majority that endorses rejection. Of course, this philosophical worldview should be open to debate and I am open to change. It is my intense desire to change, however, that has only deepened this view. Listen for and ask people why existence is good. The answers are always completely unsatisfying. Some sort of endowment effect is typically to blame, even among the staunchest atheists and scientists. “Well we’re alive already, so we might as well give it meaning and purpose while extracting the most happiness out of life as possible.” I agree with that statement entirely, but it does not then follow that we should create more life. Given that we are alive, find some meaning and learn to enjoy while minimizing suffering. Don’t go out of your way to bring more life into existence though, because existence itself isn’t good. Making the most out of a bad doesn’t make it good, just less bad. Several reasons for this misstep in thinking are laid out by Benatar, including evolution selecting for optimism, self-deception as a coping mechanism, and the instincts of survival and reproduction that are reinforced via social norms and religions. If convincing people they are in fact wrong, or at least showing people there is an alternative way of thinking, is the most good one can do, then much of the fuss of global issues can somewhat melt away. One could spend their life supporting institutions like the Future of Humanity Institute, which support an acceptance worldview, or one could try to point out to those very sophisticated, intelligent, and rational folks why they are focused on the wrong problem. That would have huge marginal impact because almost no one is doing it. On the other hand, those very smart people may be able to turn around and convince me that progress is indeed possible and that a pessimistic view of humanity should not be undertaken in support of rejectionism. That is a tall order on their part, but one I would happily welcome. I would love nothing more than to be shown credible evidence that progress is in fact possible. The key progress would be that of moral progress, not material progress. It is obvious that we have had material progress. The last two hundred years have been incredible in that regard. However, people adapt to material progress rather quickly and life satisfaction seems to improve little. Furthermore, even in a world of complete abundance and no scarcity, does anyone honestly believe that suffering would cease to exist? Would we not continue right along with our endless violence, murder, rape, torture, maliciousness, and emotional abuse and victimhood? Tyler Cowen’s recent book, The Complacent Class, contained a remarkable passage quoted from 1177 B.C., which read, The economy of Greece is in shambles. Internal rebellions have engulfed Libya, Syria, and Egypt, with outsiders and foreign warriors fanning the flames. Turkey fears it will become involved, as does Israel. Jordan is crowded with refugees. Iran is bellicose and threatening, while Iraq is in turmoil. AD 2031? Yes. But it was also the situation in 1177 BC, more than three thousand years ago, when Bronze Age Mediterranean civilizations collapsed one after the other, changing forever the course and the future of the Western world. It was a pivotal moment in history— a turning point for the ancient world. (pp. 202-203) Humans seem, for evolutionary reasons, to be incapable of living without causing the pain and suffering of others. Perhaps moral progress is possible, but it clearly hasn’t happened much in the previous three thousand years. Do we need three thousand more or should we just conclude that the majority of humans will never be capable of the type of moral progress necessary? I would tend to believe the latter. This belief does not rest on Cowen’s passage only, but also on numerous examples. Neurobiology and the Development of Human Morality walks the reader through a host of problems with overcoming abnormal development in humans. Nobel Laureate Daniel Kahneman has shown us that we often feel the “bad” in life roughly twice as strongly as the “good”. Daniel Gilbert and Matthew Killingsworth have done work that shows “mind wandering” makes us unhappy and then went on to show that much of our mental activity (47%) throughout the day is mind wandering. We better hope no more than three percent of the rest of our day spent in active attention doesn’t make us unhappy or there is a very weak case to be made that the majority of life is spent happily. The best we might hope for if the majority of our time is spent in suffering is that the sea of unhappiness is swamped by a few high points here and there. Providing additional weight to increase the average in this way would only enhance the argument for utility monsters being okay though! I’m not sure most people are willing to do that, but I am not opposed to endorsing that view and it would be one view in support of a superintelligent AI replacing us. In any case, that does seem to be how our memory works at least. Benatar cites that, “when asked to recall events from throughout their lives, subjects in a number of studies listed a much greater number of positive than negative experiences” (Kindle Locations 674-676). Of course, Benatar’s main point isn’t that the good does swamp the bad, if only in recall, it’s that no swamping is possible in principle because of the asymmetry between existing and not existing, i.e. not suffering in non-existence is “good”, but not experiencing pleasure or happiness in non-existence is “not bad” when we need it to be “bad” for a symmetry to occur. Noting the above makes plain what would need to happen for existence to be considered okay. Either the presence of pain in existence must disappear entirely, or the absence of pleasure in not existing must be shown to be bad. Neither seems likely.
Whether moral progress in regards to suffering is possible seems to be of the utmost importance for accepting rejectionism. The only information I’m currently aware of that points in this direction somewhat is Steven Pinker’s The Better Angels of Our Nature. This tome provides hundreds of pages evidencing that we are currently living in the “safest” time period in history and that violence has declined. Many have disagreed with his research and presentation of it, but I don’t think even that is necessary to claim that his premise of decreased physical violence in no way means a decrease in suffering necessarily. I am happy to be living in such a safe time period. Truly. That doesn’t mean that the motive to cause suffering or the psychological capacity to experience undue suffering has decreased in any way (remember, we need zero!). We still react excessively poorly when we find a loved one has “cheated” on us. We still behave passive aggressively. We still eat meat and cage animals, although admittedly progress seems to be occurring on this front, but it could be my own perception as we absolutely have more caged animals now relative to any time period in history. We still have slavery. Psychopaths still exist. Sociopaths are not going away. So to say we no longer suffer from mutilation and torture in a public square (see the Middle East, however) is not to say much in reality. Existence is still rife with both physical and psychological pain. To summarize, existence is not good when compared to the alternative of non-existence and should be rejected. Moral progress seems, from all evidence, to be impossible for humans, despite increased safety and wealth. So how do we live? Well for starters, it is totally up to us whether we do or not. Ending our lives is a perfectly legitimate action, although of the egoist variety as it is done for the self. The altruistic action would be continue living and spreading the worldview of rejectionism. This could do more to alleviate suffering than any other single action. In terms of effective altruism and application of 80,000 Hours criteria of scale, neglectedness, and solvability, existence appears to be at the top of the list of problems for now. I was recently asked what kind of job would make me not upset. I was asked this after stating I was feeling upset about my work, my job, and teachers as a group in general. It’s a good question and one that I often think about, but have never actually had to voice an answer to for someone else to hear.
I think I’d enjoy a job that lets me help others achieve their own self-selected goals while feeling competent in the process. It’s great seeing someone achieve a goal they were previously unsure they were capable of achieving and knowing you played a critical role in that accomplishment. I've experienced this feeling from tutoring math in small groups and one-on-one, teaching adults English as a second language, and training a small mix of people at the gym. I don’t think this does or even can happen in the current K-12 system. While I do think the system is to blame for this, it doesn’t have a mind of its own and so any change must start with teachers. Teachers Must Stop Following Orders Standards. Testing. Subjects. Curriculum. Content. Concepts. Skills. All of these are ordered from above in a top-down process. I’ve never seen a student walk into a classroom and say, “I really want to learn standard 5.4-1 today!” If any of these mandates happen to overlap with student desire, it is entirely by chance. That’s not good enough. If teachers have any interest in helping students achieve self-selected goals (i.e. being “student centered”) that benefit themselves and society, we can’t start with a pre-selected package that “must” be taught. There are no sacred cows and nothing must be taught. There is more than enough room in the world for people of all sorts to pursue any number of goals and levels of mastery. In fact, it’s a good thing that people do this (see below on economics). The next time a federal department, state department, district, or administrator orders us to teach a specific item, we should all refuse. Lets stick up for the well-being of students and society and facilitate their growth via accomplishing their goals. Teachers Need to Let Go of Subjects Closely related to following orders is the excess value teachers assign to what we already know. Subjects are not innately valuable. No specific person needs to know chemistry to live a fulfilled life that contributes to society and has purpose. We are all better off when some person or persons know chemistry and can innovate and produce new goods and services as a result of that knowledge, but the vast majority of people simply don’t need that knowledge. So let it go! Kids need to understand how to think critically, which means asking why a whole lot, finding and utilizing valid sources, and not being fooled into dubious beliefs. For example, I don’t know much about the finer points of advanced physics, but I do know that world-class physicists can put satellites into orbit and get my GPS to work exactly right. They’ve earned trust as valid sources because their knowledge “works” whether I believe them or not. Sources without this credibility can and should be largely ignored. Teachers Need to Be Less Empathetic Paul Bloom recently released a book entitled Against Empathy: The Case for Rational Compassion, which he talked about at length (among other things) in this podcast. The general idea is that people can actually be too empathetic towards the suffering of some people at the expense of others. The classic example in his mind is that of parents. Parents care overly much about their own children and as a result spend far too much time, energy, and money on them relative to other children who could benefit far more. This applies to teachers as well. Teachers stay after school to help students study for upcoming high-stakes testing all the time. They take work home with them to do on weekends and late at night. They buy their own supplies. They spend much attention trying to make students’ lives easier through various uses of calendars, reminders, and online platforms that students can check when they forget. These are all accommodationist strategies. They allow the system to continue to persist by enabling it via harder and harder work. We should not support it in these ways. Rather we need to focus on the things of greatest benefit to whatever the student goal at hand is. The work of value that can’t be finished in an eight hour school day is the work you are most looking forward to coming in and finishing the next day! It gives you reasons to hop out of bed and show up early. It doesn’t mean grinding away and burning the midnight oil. Working on genuine problems in interdisciplinary settings is exciting and doesn’t require cramming for a test, marking at home, or setting 100 reminders. It’s hard to forget what you are working on when you are super interested in it, you find immediate value in it, and it isn't swamped by 20 other to-do list items. Teachers Must Understand Economics Better On the whole, teachers seem to lack any understanding of opportunity cost, comparative advantage, or the process of economic growth as a result of new ideas. Opportunity cost says that everything has a cost. If we choose to do one thing, we implicitly choose not to do something else and so we forego that other opportunity - hence opportunity cost. This should be at the top of every teacher’s mind when working with students. Is spelling important? Sure, but what are you giving up to teach perfect spelling in an age of autocorrect? The chance to learn coding? If that is the case, the value of coding is almost certainly greater than the ability to spell correctly when writing by hand and should be passed over in favor of more coding, or some other more valuable and interesting topic. Comparative advantage is the idea that we should specialize in whatever has the lowest opportunity cost for us. This is a relative advantage, not an absolute one, and so every person on the planet will have a comparative advantage in something, just not all the same somethings. If I can produce widgets with a lower opportunity cost than you, I should produce widgets and you should produce something else. We can then trade with each other and we are both better off. Comparative advantage directly implies that we shouldn’t all be doing the same things. What do we see in K-12 schools? Everyone doing the same things! This means less diversity and less freedom to pursue personal interests and develop mastery in niche areas. This brings us to the process of economic growth, which fundamentally rests on new ideas that give rise to ever greater productivity (more output from same input). Who doesn't want more per dollar? We need people doing different things because that is how we get new goods and services of value. If you don’t think new goods and services is of ultimate value, I recommend living in the stone age for a week and seeing how you enjoy it. Effects of the 4 Changes I really believe that if teachers stopped listening to others tell them how to do their jobs, weren’t so attached to their subjects of interest, were less focused on the short-term suffering created by the current system, and understood the real need for diversity and weighing up opportunity costs, then students would be much freer to pursue their own goals and teachers would be much more capable of helping them achieve those goals without the needless burnout we see so much of today. Focusing on truly student-centered learning could unlock a sea of student passion, interest, and creativity accompanied by the long-term motivation needed to work hard and solve meaningful problems. We need novel solutions to all sorts of local, national, and global issues and we won’t get them by teachers remaining subservient to the current system. This type of change needs to start on the frontlines with teachers acting as professionals, who don’t take crap from anyone and don’t continue to fail students by not standing up for what they really need. As a nice benefit from all these changes, I think teaching would become much more fulfilling. It'd be so much easier to understand what success means and looks like when one can see the elation on the face of students who are growing and becoming ever more actualized as a result of accomplishing intrinsically meaningful goals. The first personally meaningful goal I ever accomplished was finishing a half marathon in college. I chose to do it, with some nudging from my girlfriend at the time. No one forced it on me. This was followed by self-publishing a Kindle Amazon book at 24 years old, climbing Mt. Whitney at 25 years old, and squatting over 400 pounds at 26 years old. All of these were done outside of school and none of them happened in K-12. That is too little, too late and the students of today can do so much better if we help and guide them. I hope for a future where K-12 students are regularly publishing books, making YouTube videos, coding apps, and starting NGO's that change the world. To do any that, we have to stop pretending we know what is best for them and get out of their way. We're here to help, not impose. How does one become weak? Attend a typical school and take dozens of tests in the manner portrayed immediately above.
By typical, I have a very broad view in mind. Public, private, charter. They're mostly all the same. As humans, we are animals with big brains that evolved to let us solve problems, mainly through movement. By sensing the world around us via physical perception and cognitive processing, we can move about the world to solve the problems of securing food, sex, and safety. These two primary aspects - problem solving and movement - of being human go almost entirely absent in any school you walk into. Bodies and minds are rarely given genuine challenges and so any natural strengths tend to atrophy. Sure, we have PE, health class, and athletics for the body. Students most likely play a couple games half heartedly, learn a little bit about sex, and possibly become varsity athletes in a sport or two if they are lucky. Very rarely is intense exercise and good nutrition taken seriously. Many (most?) students leave high school unable to do a single pull up, run a mile quickly, or feed themselves properly. They lack nearly any physical vitality and the exception only proves the rule in this case. When it comes to problem solving, it is almost entirely contrived. Students learn very quickly that whatever they are working on in class is of no use to anyone outside of class. Problems simply aren’t genuine. If they don’t solve the problem, they get a lower grade. If they do solve the problem, so what? Millions of other people around the world have solved the exact same one (Pythagoras’ theorem anyone?). It does not contribute to the advancement of the community or world in any way. When weak bodies and minds are produced together, we are left with weak people. People that are incapable of focusing on what is important or actively moving to solve problems and improve life. A society with weak people can only last so long and school ought to blamed for the majority of problems today. This is not the fault of the children/students who do not come into school lazy, unmotivated, and lacking curiosity. It is the fault of adults making bad decisions on their behalf. When a grade 7 common core state standard for English reads, “Analyze how a drama’s or poem’s form or structure (e.g., soliloquy, sonnet) contributes to its meaning,” we have clearly gone very wide of the proper aim of education. Millions of collective student/teacher hours are spent on these standards each year. Can we honestly say that having this skill will improve the life of the individual student or community with a high degree of certainty relative to other options available for topics of instruction? With health expenditures equal to over a sixth of US GDP each year, it would seem far more prudent to spend the would-be poetry time on teaching students how to love exercise and nutritious food. They will absolutely feel and think better, period. All evidence suggests that both body and mind function better with regular exercise and quality food. It is simply overwhelming. Spark is a good introduction to some of this evidence. Alternatively, a high school geometry common core standard reads, “Give an informal argument for the formulas for the circumference of a circle, area of a circle, volume of a cylinder, pyramid, and cone. Use dissection arguments, Cavalieri’s principle, and informal limit arguments.” Again, millions of collective class hours are spent on these standards each year. If a student is able to give this informal argument, what has tangibly improved? It may work as a stepping stone to higher math and university entrance, but as someone with a math degree, it is hard to see how this helps. I could not give this informal argument without looking it up myself and that’s the point - I can look it up when needed! Wouldn’t all this time be better spent identifying real problems in the world that eventually produce a need for the math? Most people and problems will have no need for the geometry standard stated above and so the opportunity cost associated with it becomes larger as the time could have been spent on something else. The world is full of problems that can be genuinely and authentically tackled by students of any age. They ought to be exposed to them sooner, not later. I’ve earned three degrees from university and I can honestly say I have never once encountered a genuine problem where my solving it would have mattered to the wider community or world, let alone me. So if we aren’t producing vigorous, capable physical bodies or problem-solving minds, what are we creating? Sick, overweight, obese, degenerate bodies, often attached to flaccid minds that can manage watching TV an average of 36 hours per week, but are simultaneously exiting the labor force at alarming rates over the past 20 years, particularly among young men. I, for one, love both English and math. This is not a tirade against either subject as such. I have degrees in both and have taught both for thousands of hours to other students. That doesn’t mean they are intrinsically worthwhile or valuable. They aren't, they're instrumental to the problems they help to solve. Physical health and the curiosity to find and the desire to solve problems are intrinsically valuable. The world is no longer willing to let us relax complacently into success. Our children will most likely not be better off than we are economically by going to college and getting a job they can stay at for 40 years with a strong retirement from pension and social security. The baby boomers got lucky and their “winning” formula is dooming entire generations after them to high rates of illness to the point where we are much more likely to die from obesity and suicide than famine and war. Learning six subjects and getting good grades on tests gets you into university and that secured the future for those baby boomers setting policy now. For whatever reason, those same people are ignoring that good grades in six subjects gets you very little today. It simply isn’t good enough today. Different is needed, not more. I look forward to a day when every high school graduate leaves K-12 with a strong body and a clear personal mission of how to make the world a better place with the skills to do it. Some will go to college, but most probably won't. That requires a drastic change in what school looks like. Schools must focus on vitality and growth, not stress induced apathy that leads to breakdown. |
