Study: Bald head can be business winner NYP2001040607 - 06 APRIL 2001- NEW YORK, NEW YORK, USA: Political activist Al Sharpton jokes about hip hop mogul Russel Simmons bald head before the start of the National Action Network Keeper of the Dream Award ceremonies hosted by Sharpton April 5, 2001 in New York City. rw/ep/Ezio Petersen UPI PHILADELPHIA, Oct. 3 (UPI) -- A lecturer at the University of Pennsylvania's Wharton School of business says studies show men with shaved heads are perceived as better leaders. 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.
