Today's post, Leaky Generalizations was originally published on 22 November 2007. A summary (taken from the LW wiki):

The words and statements that we use are inherently "leaky", they do not precisely convey absolute and perfect information. Most humans have ten fingers, but if you know that someone is a human, you cannot confirm (with probability 1) that they have ten fingers. The same holds with planning and ethical advice.

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 Not for the Sake of Happiness (Alone), 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.
