Is the idea here to counsel us against some sort of halo effect? Eliezer Yudkowsky has told me a lot of interesting things about heuristics and biases, and about how intelligence works, but I shouldn't let this affect my judgement too much if he recommends a movie?

Or is it more than that - just that I should be careful when reading anything by Eliezer, and take into account the fact that I'm probably slightly too inclined to trust it, because I've liked what came before? Because then of course, we have the issue that I should be more likely to trust an author who is usually right - and this just says that I should be careful not to trust them too much more.
