     Beauty has always been regarded as something praiseworthy.Almost everyone thinks attractive

people are happier and healthier, have better marriages and have more respectable occupations.

Personal consultants give them better advice for finding jobs.Even judges are softer on attractive

defendants(被告). But in the executive circle, beauty can become a liability.

     While attractiveness is a positive factor for a man on his way up the executive ladder, it is harmful

to a woman.

     Handsome male executives were thought as having more integrity than plainer men；effort and

ability were thought to account for their success.

     Attractive female executives were considered to have less integrity than unattractive ones；their

success was attributed not to ability but to factors such as luck.

      All unattractive women executives were thought to have more integrity and to be more capable

than the attractive female executives.Interestingly, though, the rise of the unattractive overnight successes

was attributed more to personal relationships and less to ability than that of attractive overnight successes.

      Why are attractive women not thought to be able?An attractive woman is thought to be more

feminine and an attractive man more masculine(有男子气概的)than the less attractive ones.Thus, an

attractive woman has an advantage in traditionally female jobs, but an attractive woman in a traditionally

masculine position appears to lack the"masculine"qualities required.

     This is true even in politics."When the only clue is how he or she looks, people treat men and women

differently, "says Anne Bowman, who recently published a study on the effects of attractiveness on

political candidates.She asked 125 undergraduate students to rank two groups of photographs, one of

men and one of women, in order of attractiveness.The students were told the photographs were of

candidates for political offices.They were asked to rank them again, in the order they would vote for

them.

      The results showed that attractive males utterly defeated unattractive men, but the women who had

been ranked most attractive invariably received the fewest votes.
