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.
I've installed various mental habits from my time on Less Wrong. My habit of trying to notice rationalization as it happens, in combination with the "Tsuyoku Naritai" attitude, led me to become much more serious about physical fitness. In the last fourteen months, I've gone from moderately overweight and sedentary to lean, fit, and strong, with a minimum of the motivation issues that had previously prevented me.
I've never attended CFAR and am not especially deeply involved with LW, so this may not really be the kind of example you're looking for.
