My experience is exactly the reverse of this.
Agree.
Insufficient data for a meaningful answer. Query: do you refer only to empathy for large groups of distant people, or do you also suspect that nerds have less empathy for individuals in their social groups? It is not obvious that these would be related.
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.)
