You would be surprised to learn how often I talk to Less Wrongers who have been corrupted by a few philosophy classes and therefore engage in the kind of philosophical analysis which assumes that their intuitions are generally shared.

Despite being downvoted in this comment, I think Eliezer is generally right that reading too much mainstream philosophy — even "naturalistic" analytic philosophy — is somewhat likely to "teach very bad habits of thought that will lead people to be unable to do real work."
