I'm surprised, Gully; that's an insight that comes from cognitive science! 
Oh please, thatīs academic gloryhogging for one disclipine. A wide variety of research has shown this to be the case.
And besides, Iīm not totally hostile to cognitive science (actually you will be happy to discover I dislike behaviourism even more) just evolutionary pschology and especially itīs "media champions".
