Apparently, pace my own username, you don’t know who the fuck I am.

I don’t think any of that first paragraph is true. LessWrong and EA very blatantly do not teach people how to spot fallacious reasoning. Nor does the culture of either encourage the adherents of their one movement to repress their “irrational” emotions. Fallacious reasoning, emotional reasoning, irrational thinking - all three of these self-evidently ran rampant in the culture, so there has to be something else going on here which would explain both what the culture is like and why you have an impression that seems to line up so squarely with their self-presentation.

Rather, it seems that what happens at LessWrong and EA is roughly that a charismatic self-presentation of “rational thinking” (with attendant ideas along the lines of repressing one’s emotions and so on) hooks in impressionable people, who - like victims of any multi-level marketing scheme - quickly replace their own styles and habits of thought with those propounded and taught by the movement. So those people do do something like “repress” their emotions, but only in the sense that they repress those styles of thought and emotional presentation which had previously come naturally to them. But of course the movement also teaches that it is right and proper or that there is even a sort of duty to make impassioned (whiny) emotional appeals to this or that privileged source of the right kind of emotions to feel (such as feeling indignant about normie reasoning, or feminism, or whatever), which are (some would say fallaciously) considered above rational criticism themselves.

You can see that sort of thing play out in basically any rationalist discussion or article at Vox’s “Future Perfect”!

So what you describe with respect to drugs and so on is true enough but misses the point. It’s rather that throughout the movement there’s a strong current of precisely the things that in its self-presentation the movement is supposed to ward off. The drug scene isn’t an outlet for repressed feelings, it’s just a particular place (of many) towards which the movement’s leaders have directed the energies (which they don’t repress but encourage) of their followers.

The shame and guilt thing is a separate issue, it has nothing to do with the conscious or directed repression of emotions under the auspices of the movement.
