I could quibble with "successful at", but I think the analogy still holds in any case. Virtually everyone is interested in defending themselves, at least, from physical threat.
Martial arts are one approach to being more effective at defense, and rationality is a similar approach to being more effective at reaching goals in general.
We should absolutely be quibbling about "successful." Someone comes to me with advice for achieving my goals: "I know just the ticket, all you have to do is swallow this giant pack of lies." Well, couldn't they be right?
I think it's a rare individual who would actually be in less physical danger if they were better at martial arts. The scope of rationality is similarly limited -- it's not useful for every one, or for every goal.

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. It is the first post in the series; the introductory post was here, 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.
