This is a repository for major, life-altering mistakes that you or others have made. Detailed accounts of specific mistakes are welcome, and so are mentions of general classes of mistakes that people often make. If similar repositories already exist (inside or outside of LW), links are greatly appreciated.
The purpose of this repository is to collect information about serious misjudgements and mistakes in order to help people avoid similar mistakes. (I am posting this repository because I'm trying to conduct a premortem on my life and figure out what catastrophic risks may screw me over in the near or far future.)
My reference class was "traits I would want in a friend". I don't really care about how often my friends feel the need to be alone.
Extroversion is probably correlated with happiness - but then again, if we accept introversion-extroversion as intrinsic personality traits, who is to say that a lonely, socially awkard extrovert won't give the same test results as a sad introvert? Correlation(extroversion, income) supposedly has a inverse U shaped curve.
Actually, the truth is I don't pick friends based on raw happiness either...it was shorthand for general emotional maturity. I wouldn't want to be less friends with someone if they were depressed, for example - it's just that I don't want anger, anxiety, insecurity, and other sorts of aggression directed at me, and people who frequently experience negative emotions are more likely to direct aggression at others.
