I think the fact that the Mind Projection Fallacy is a really strong bias in humans significantly decreases the weight of that possibility. Smart people think it may be true because that sounds like the easiest explanation, for a human, not because they actually thought a lot about it from a strictly rational point-of-view.
That's some kind of general counter-argument against "trust the majority", I think. When you learn that the majority has some kind of bias that supports its belief, you should decrease the strength you assign to the evidence "the majority thinks it's true". P(A|B)/P(A|!B) is small.

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 Zen and the Art of Rationality, 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.
