This describes really well how I feel about the influence of epistemic rationality improvements in my life. They are often small and subtle enough that it is easy to overlook their importance in the short term. In the longer term the difference in clarity of thought between present me and past me is striking based on surviving material. It is only when doing this comparison that many of the differences actually become intelligible.
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.)
