I think a more careful reading of the whole post, and particularly the sentence immediately following the one you quoted, will show that Claudus was not claiming that this feeling is true. The statement is that a lot of people feel a particular way. Do you really disagree that is the case?

For what it's worth, I think one of the points of the blog post is that this bias is more difficult to spot than Claudus's statement would imply, and I tend to agree with that.
