By teaching people using arguments from authority, he may be worsening the primary "sanity waterline" issues rather than improving them. The articles, materials, and comments I've seen make heavy use of language like "science-based", "research-based" and "expert". The people reading these articles in general have little or no skill at evaluating such claims, so that they effectively become arguments from authority. By rhetorically convincing them to adopt the techniques or thoughts, he's spreading quite possibly helpful ideas, but reinforcing bad habits around accepting ideas.
My immediate reaction was to disagree. I think most people don't listen to arguments from authority often enough; not too often. So I decided to search "arguments from authority" on LessWrong, and the first thing I came to was this article by Anna Salamon:
Another candidate practice is the practice of only passing on ideas one has oneself verified from empirical evidence (as in the ethic of traditional rationality, where arguments from authority are banned, and one attains virtue by checking everything for oneself). This practice sounds plausibly useful against group failure modes where bad ideas are kept in play, and passed on, in large part because so many others believe the idea (e.g. religious beliefs, or the persistence of Aristotelian physics in medieval scholasticism; this is the motivation for the scholarly norm of citing primary literature such as historical documents or original published experiments). But limiting individuals’ sharing to the (tiny) set of beliefs they can themselves check sounds extremely costly.
She then suggests separating out knowledge you have personally verified from arguments from authority knowledge to avoid groupthink, but this doesn't seem to me to be a viable method for the majority of people. I'm not sure it matters if non-experts engage in groupthink if they're following the views of experts who don't engage in groupthink.
Skimming the comments, I find that the response to AnnaSalamon's article was very positive, but the response to your opposite argument in this instance also seems to be very positive. In particular, AnnaSalamon argues that the share of knowledge which most people can or should personally verify is tiny relative to what they should learn. I agree with her view. While I recognize that there are different people responding to AnnaSalamon's comments than the one's responding to your comments, I fear that this may be a case of many members of LessWrong interpreting arguments based on presentation or circumstance rather than on their individual merits.
What is your opinion on rationality-promoting articles by Gleb Tsipursky / Intentional Insights? Here is what I think:
Trying to teach someone to think rationally is a long process -- maybe even impossible for some people. It's about explaining many biases that people do naturally, demonstrating the futility of "mysterious answers" on gut level; while the student needs the desire to become stronger, the humility of admitting "I don't know" together with the courage to give a probabilistic answer anyway; resisting the temptation to use the new skills to cleverly shoot themselves in the foot, keeping the focus on the "nameless virtue" instead of signalling (even towards the fellow rationalists). It is a LW lesson that being a half-rationalist can hurt you, and being a 3/4-rationalist can fuck you up horribly. And the online clickbait articles seem like one of the worst choices for a medium to teach rationality. (The only worse choice that comes to my mind would be Twitter.)
On the other hand, imagine that you have a magical button, and if you press it, all not-sufficiently-correct-by-LW-standards mentions of rationality (or logic, or science) would disappear from the world. Not to be replaced by something more lesswrongish, but simply by anything else that usually appears in the given medium. Would pressing that button make the world a more sane place? What would have happened if someone had pressed that button hundred years ago? In other words, I'm trying to avoid the "nirvana fallacy" -- I am not asking whether those articles are the perfect vehicle for x-rationality, but rather, whether they are a net benefit or a net harm. Because if they are a net benefit, then it's better having them, isn't it?
Assuming that the articles are not merely ignored (where "ignoring" includes "thousands of people with microscopic attention spans read them and then forget them immediately), the obvious failure mode is people getting wrong ideas, or adopting "rationality" as an attire. Is it really that wrong? Aren't people already having absurdly wrong ideas about rationality? Remember all the "straw Vulcans" produced by the movie industry; Terminator, The Big Bang Theory... Rationality already is associated with being a sociopathic villain, or a pathetic nerd. This is where we are now; and the "rationality" clickbait, however sketchy, cannot make it worse. Actually, it can make a few people interested to learn more. At least, it can show people that there is more than one possible meaning of the word.
To me it seems that Gleb is picking the low-hanging fruit that most rationalists wouldn't even touch for... let's admit it... status reasons. He talks to the outgroup, using the language of the outgroup. But if we look at the larger picture, that specific outgroup (people who procrastinate by reading clickbaity self-improvement articles) actually aren't that different from us. They may actually be our nearest neighbors in the human intellectual space. So what some of us (including myself) feel here is the uncanny valley. Looking at someone so similar to ourselves, and yet so dramatically different in some small details which matter to us strongly, that it feels creepy.
Yes, this whole idea of marketing rationality feels wrong. Marketing is like almost the very opposite of epistemic rationality ("the bottom line" et cetera). On the other hand, any attempt to bring rationality to the masses will inevitably bring some distortion; which hopefully can be fixed later when we already have their attention. So why not accept the imperfection of the world, and just do what we can.
As a sidenote, I don't believe we are at risk of having an "Eternal September" on LessWrong (more than we already have). More people interested in rationality (or "rationality") will also mean more places to debate it; not everyone will come here. People have their own blogs, social network accounts, et cetera. If rationality becomes the cool thing, they will prefer to debate it with their friends.
