There's apparently something about a man with a shaved head that projects masculinity. Maybe it's the testosterone.
"I'm not saying that shaving your head makes you successful, but it starts the conversation that you've done something active," tech entrepreneur Seth Godin, told The Wall Street Journal.
In one experiment, Wharton researcher Albert Mannes showed 344 people photos of the same man, one with hair and the other with a digitally photo-shopped bald head.
The test subjects said they perceived the bald man as more dominant. Men with thinning hair were perceived as least attractive and powerful.
Mannes' three tests were the basis for his study "Shorn Scalps and Perceptions of Male Dominance," published online and in the coming issue of the journal Social Psychological and Personality Science.
Amazon.com Chief Executive Officer Jeff Bezos, Netscape founder Marc Andreessen, and Dreamworks Animation chief Jeffery Katzenberg, have all sported bald or closely clipped pates.
