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.)
Some examples follow (caveat: these are generalizations based on small data-sets and each rule has exceptions. But I feel they're broadly true. Others, please support or contradict these 'rules').
My non-nerdy friends are more open to physical touch, such as hugging, playful touches during laughter, comforting touches and so on. Nerdy friends seem to restrict themselves to handshakes; some find even handshakes awkward.
More inclined to solidarity rituals. Typical example: non-nerd enjoys sports. Nerd dismisses them as artificial constructs designed to provide conflict as entertainment, and therefore doesn't want to participate in the ritual. Another example: nerds will typically take most conversations towards arguments/debates; non-nerds will see conversation as a solidarity ritual and keep it's flow more towards participant enjoyment.
Larger amounts of empathy. Non-nerdy friends seem more open to non-judgmental empathy. Nerds tend to dismiss someone's pain simply because it's part of a larger pattern. Example: non-nerdy friend says the condition of disabled people in India/China is very sad. Nerdy friend: yes, India/China have large populations and therefore life is cheap; and revels in his ability to "explain it away". The conversation becomes stunted because the nerd has refused to participate in the "empathy-field" that the non-nerd wanted to generate.
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.
