I think it's past time for another Stupid Questions thread, so here we go.
This thread is for asking any questions that might seem obvious, tangential, silly or what-have-you. Please respect people trying to fix any ignorance they might have, rather than mocking that ignorance.
A question that has been asked before, and so may be stupid: What concrete examples are there of gains from CfAR training (or self-study based on LessWrong)? These would have to come in the form of very specific examples, preferably quantitative.
E.g. "I was $100,000 in debt and unemployed for 2 years, and now I have employment earning twice what I ever have before and am out of debt."
"I never had a relationship that lasted more than 2 months, but now am happily married."
"My grade point average went up from 2.2 to 3.8"
"After struggling to diet and exercise for years, I finally got on track and am now in the best shape of my life."
etc.
Search "Rationality Diaries" on LW to see a huge archive of examples from recent years. (Those are places where users upload recent stories of victory from their lives.)
