This is a tangent, but the long discussion of poisons reminded me of my recent discovery of the (not surprising in retrospect) limitations in our knowledge. In Plato scholarship, there was for some time a controversy about Socrates' death scene in Phaedo; some scholars argued that death by hemlock is much more unpleasant than the peaceful scene Plato describes, so Plato either got it wrong or misrepresented it for some purpose. But more recent scholars mostly think that Plato probably did describe it accurately, with the alternate interpretation arising because quite a number of different things have been called "hemlock" over the years, some of which produce very unpleasant deaths, but at least one of which produces pretty much what Plato describes. It appears that one reason that there was ever a controversy is that we often don't know very much about how poisons cause deaths; once something is identified as poisonous, people just start avoiding it, so we don't tend to accumulate many further cases of death by that cause to observe.

Except, presumably, in cases where people deliberately use those poisons as means of execution, murder or warfare?

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 Mirrors and Paintings, 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.
