On a related note, if the students of a rationality teacher routinely produce more rational students, this is evidence that they can recognize and teach rationality to others.
This does not necessarily mean they are good at applying rationality in their everyday lives, which goes somewhat against Eliezer's point that someone respected as a good teacher should also be respected for what they do outside teaching.
So, what this means is that there should be two categories for respect related to this: One for ability to teach and train others in rationality, and another for how they use rationality in their life.

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 Whining-Based Communities, 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.
