Today's post, The Bad Guy Bias was originally published on December 9, 2008. A summary:
Humans have a tendency to perceive tragedies caused by agents as worse than tragedies caused by other sources. This can cause us to, among other things, worry more about future catastrophes as a result of malevolent agents than as a result of unplanned events.
Discuss the post here (rather than in the comments to the original post).
This post is part of the Rerunning the Sequences series, where we'll be going through Eliezer Yudkowsky's old posts in order so that people who are interested can (re-)read and discuss them. The previous post was True Sources of Disagreement, and you can use the sequence_reruns tag or rss feed to follow the rest of the series.
Sequence reruns are a community-driven effort. You can participate by re-reading the sequence post, discussing it here, posting the next day's sequence reruns post, or summarizing forthcoming articles on the wiki. Go here for more details, or to have meta discussions about the Rerunning the Sequences series.
I suppose that works for pre-scientific, pre-rational thinking: back when you couldn't do a thing about nature, but you could do a thing about that schmuck looking at you funny.
However, now, as humanity's power grows, we can actually do something about nature: we can learn to predict earthquakes, build structures strong enough against calamity, vaccinate against pestilence, etc etc.
So the bias, I suppose, arises from evolution being too slow for human progress.
I think you're missing Eugine's point.
Consider someone that may or may not rape your daughter - the probability that he does so is function of how likely it is you'll spend your day and nights hunting him down in order to slowly torture him to death, with no concern for law or personal safety.
Consider an earthquake that may or may not destroy your house. The probability that it does so is independent of what you precommit to doing afterwards.
Sure, in both cases we can prevent the tragedy through other ways, but that's not the main issue.
