An interesting article from the Wall Street Journal.
Men with shaved heads are perceived to be more masculine, dominant and, in some cases, to have greater leadership potential than those with longer locks or with thinning hair, according to a recent study out of the University of Pennsylvania's Wharton School.
Whenever I read "according to a recent study out of..." I always look to see who paid for the study. More times than not, the actual underwriters are not revealed. This is the case in the Journal with this article too.
