    There would be a certain amount of resistance to that, but only because we have been there before and found that such claims tend to be unfounded.

    Okay, I'm done with this conversation, because you're clearly blind. I don't know whether it's willful, but there is a long history of huge resistance to that exact concept. Career-destroying resistance that takes no note of the strength or weakness of the actual research and occasionally edges into violence.

    Note that I agree that the apparently race-related variance in cognitive ability is proven to be cultural, not racial, in origin. Further, I don't believe races are actually a biological thing; they're primarily a social construct. My favorite evidence of that is the research showing that going to prison may turn you black. But it's critical that researchers not be attacked professionally and personally for uncomfortable ideas.

    You really don't want to believe that happens. But you're flat wrong.

    Without all the tracking and authoritarian features they've been crying for all these decades. Why do we suddenly need them now?

    I don't think we do.

    However, your question is disingenuous. Even if the Internet has gotten along well so far (which is a claim that really needs to be defined and supported, but I'll ignore that), society's level of dependence on the Internet clearly has changed. As the Internet becomes more and more central to everyone's lives, the context and implications change. When there were only a handful of horseless carriages tooling around on rutted dirt roads the need for regulating them was nil. Within a decade virtually the same vehicles were a major part of traffic and the need for regulation became significant. Within a few more decades they became central to life in the developed world and regulation became critical.

    If your argument is "why now?", there is no need for a sharp answer. As a process of gradual change continues, problems become gradually more clear and the level of interest in addressing them gradually rises until it surfaces in the public discourse. This is normal.

    At this point, this is a debate that we do need to have or, more precisely, to continue having. There are difficult issues here, of how to balance the public interest in law enforcement and security against the public interest in freedom of speech, association and other actions. Anyone who admits only one side or the other of these questions needs to learn some history and to study the way the same issues have been balanced in the past, in other contexts.

    My preference is to err on the side of freedom, and even to accept a certain level of crime and public safety risk as the price of that freedom. But there is room for -- and need for -- constructive debate.

We've only had horses and camels for a few millennia, steam-powered trains for a couple of centuries, cars for just over a century and jet airplanes for a few decades... so surely using only legs to get around is better.

    Everything has pros and cons, and the only way to figure out what is better is to actually try it and observe the results. Arguing that X is better just because it's what humans have done for a long time is just stupid. In some cases it might be true, but counterexamples abound.

    Suppose, for example, that some highly qualified, methodical and determinedly unbiased researcher has conducted a brilliant set of experiments which appear to show that people of one race are consistently superior to people of another race in some important way. The work appears to be extremely well-conceived and well-executed. Now think about which universities you're familiar with would be interested in employing her and funding her research. TU would care only about the quality of her research. SJU would give at least as much weight to the potential social impact.

    This is actually quite common, especially in medical and sports sciences.

    But Haidt is talking about the social sciences. I guess I should have said "people of one race are consistently superior to people of another race in some important area of cognitive ability", to make the point clearer. (Note that I'm not making the claim that such exists; merely proposing a hypothetical of a scientific result. If you find yourself unable to grant the hypothetical premise, you should think about what that means.)

    If social justice was not interested in truth, rational argument and careful wide-ranging research without artificial limits then it wouldn't be so strong in academia.

    It should also be noted that the phenomenon Haidt is describing is less about the goals and behaviors of academics, and more about the goals and behaviors of administrators and students. Yes, researchers want to study whatever they find interesting and they tend to have a very narrow focus and relatively little concern for the big picture, especially when they're in the process of producing substantial new results. This focus is necessary and appropriate. It's when the researchers become older and their work is mostly supervisory, or when academics go into administration which leads them to be primarily concerned with internal and external relationships, that the suppressive influences arise.

    A minority of students (about 20%, according to recent research) have begun demanding that their university experience be made "safe" for them, with extensive demands for trigger warnings, safe spaces, and suppression of ideas that contradict their notions of social justice. SJUs are the ones who listen to these student demands and similar external pressures. TUs are the ones who declare that students' must be exposed to the broadest selection of views. As Chicago University put it in its letter to the class of 2020:

    Our commitment to academic freedom means that we do not support so-called “trigger warnings,” we do not cancel invited speakers because their topics might prove controversial, and we do not condone the creation of intellectual “safe spaces” where individuals can retreat from ideas and perspectives at odds with their own.

    In contrast, Brown president tries to defend academic freedom while simultaneously defending safe spaces, trigger warnings and the de-invitation of speakers who have bad ideas. Her letter to the Washington Post is written so that it's easy to extract quotes arguing for unlimited academic freedom, but the overall narrative is the opposite.

    If you truly haven't seen the suppression of academic freedom in the name of political correctness, I highly recommend that you read the first few chapter's of Steven Pinker's "The Blank Slate". Even if you don't agree with the larger conclusions of the book, the first few chapters provide a great overview of how extensively politically incorrect research has been suppressed over the last two or three decades.

    I read that blog post and he has some weird ideas about social justice. The "blasphemy" section is a great example, where he says that "Truth U" has no such thing but "Social Justice U" has many things that cannot be said. That's clearly and rather obviously nonsense.

    It is not nonsensical at all, though it is perhaps a bit hyperbolic. It might be better to say that TU aspires to mark no investigation as off limits, while SJU aspires to discover only that which does not damage social justice.

    Suppose, for example, that some highly qualified, methodical and determinedly unbiased researcher has conducted a brilliant set of experiments which appear to show that people of one race are consistently superior to people of another race in some important way.

TU would care only about the quality of her research. SJU would give at least as much weight to the potential social impact.

    In practice if someone were to actually set up either of these I think they would both simply attract trolls. Having a mixture is the best option, because none of this stuff is all that useful in isolation anyway.

    Of course real universities are not pure TU or pure SJU. Haidt's point is that we appear to be moving toward a situation where the conflicts between social justice on the left and attempts to relabel conservative orthodoxy as truth on the right are so sharp that it becomes impossible for SJU-like universities to support any research that might undermine their political goals, which in turn forces universities to decide explicitly whether they're willing to take the political risks inherent in an unconstrained search for truth. Those who are will appear to those who are not as opponents of social justice (note that there are also conservative "SJUs" who also constrain research, but in a different direction).

    As an aside, if this blog post is your first exposure to Haidt's research and ideas, you should do some reading -- and you should note that Haidt, himself, is a social justice-favoring moderate leftist. He has a tendency to apply the results of his research a little more broadly than is really warranted by the research itself, but don't let that blind you to the value of his ideas. His Moral Foundations theory is powerful and well-supported. Which isn't to say that it's "correct" in any absolute sense, science can never provide certainty, but until another theory that better fits the data comes along it's the best tool we have for analyzing the moral basis of human motives. If you're not familiar with it, you should read it.

    Haidt does little more than regurgitate Schopenhauer—badly.

    If you believe that, then you don't understand either. Really, the only commonality between them is that both view ethics and morality as phenomena to study rather than sets of principles to define. But even there, Schopenhauer lacked both the perspective and the tools needed to actually study how human ethical systems really work. That requires data gathering techniques from modern sociology and psychology and analytic techniques from modern-ish statistics. So even in the occasions where Schopenhauer's and Haidt's theories coincide, the former are philosophical, based on navel gazing, and the latter scientific, based on falsifiable research.

    Also, if you're looking for an 18th-century philosopher whose ideas track most closely to Haidt's discoveries, Hume is a much better fit than Schopenhauer. Granted that Schopenhauer was a big fan of Hume and there is a lot of commonality between their ideas.

    Put some numbers to it. Mean per capita income in 2017 was $50,392. So to fund a $12K per year UBI you have to add a 24% flat tax (ideally you should be able to offset that by cutting the progressive tax because of the other welfare programs you can cut, but let's ignore that -- particularly because this program wouldn't replace all of them.).

    Assuming two-adult households, no UBI for kids, and no change to earnings (which would not be true, see below), here are some numbers for pre-UBI income and net UBI income (income plus UBI less UBI taxes).

    $0 -- $24K
    $10K -- $32K
    $20K -- $40K
    $30K -- $47K

    $50M -- $38M

    Not bad. Of course, the big wildcard is the assumption that people stick with their current jobs / incomes. We don't really know what would happen there.

    We're probably safe to assume that in the short term some people would stop working and live on their UBI while they go to school to move themselves up the income ladder. Others might quit their current jobs and start businesses. It seems likely that there would be some changes at the bottom of the pay scales (I'm assuming that the minimum wage would be abolished with enactment of a UBI) as employers might be able to pay less because their employees would need less... but maybe not too much less because employees would feel more freedom to walk away from jobs they dislike.

    Some percentage of the low-income population might well decide that the UBI is enough for them and just choose not to work any more. I don't think this group would be large, but we can't really know.

    Assuming UBI is not available to unemancipated teens, it would have some interesting effects on teen employment, since young adults eligible for UBI would in many cases be willing to work for less than ineligible teens. I assume teens would still be paying the UBI tax.

    We really need some large-scale, long-term UBI tests to find out how people really respond, what decisions they make. And these tests need to be performed in different areas, in different cultures, because there's no reason to believe that every culture will react the same.

For subsidized loans, they a found a somewhat larger passthrough effect of 70 percent, and for unsubsidized loans, the loading of tuition is about 30 percent. Those results, which are identified through cross-sectional exposures to the changes in student federal aid programs between 2007 and 2010 and contain numerous controls for other effects, support the hypothesis that increases in federal support for higher education lead to increases in tuition and not the other way around.
