LessWrong and EA can help people to understand logical fallacies, but they can’t help people to actually understand their emotions. In fact, the culture around them encourages adherents to feel contempt for their “irrational” emotions and for people who are led by emotion.
Of course it is extremely unpleasant to repress all your emotions, and it is ultimately impossible to do so all the time. How did the LessWrong community solve this problem? Its users limited their emotional expression to acceptable forms and acceptable targets, and expressed their emotions through cult accepted techniques like taking drugs, having sex, cyberbullying leftists and writing really long blogposts.
Like most subcultures, it’s the powerful and respected people in EA who determine the dominant norms. With pretty much every leading EAist a middle-class dominant-culture American man who works in tech and wishes feminists would quit whining, it should be no surprise that the norms they created are stereotypically, nay, toxically white and masculine.
