A question for Mr Charles Murray

Hi. I heard you this afternoon on Michael Duffy's program on the radio, talking about oppressed academics telling things to the media they didn't believe in private, amongst their professional colleagues. You wrote that book "The Bell Curve".

Now tell me, if blokes are such geniuses at visual and spatial orientation, why can't they find their way around a shopping mall then? Ever? (With the possible exception of the ones with gay brains?)
