My observation of the subject is that many people have an intuition, gut feeling, opinion formed from personal experience, etc. that men and women in general have innate differences that make men (or women) more suitable for certain functions.
Sounds like you'd like to ignore the science to the contrary and just rely on your gut.
You're entitled to that, but I've found science to have a lot of usefulness.
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.
