     Beauty has always been regarded as something admirable. Almost everyone thinks that attractive people

are happier and healthier; they have better marriages and have more respectable jobs. Personal consultants

(顾问) give them better advice for finding jobs. Even judges are softer on attractive persons. But in the

executive circle, beauty can become a liability.

     While attractiveness is a positive thing for a man's rise, it is harmful to a woman's. Handsome male

executives (主管) were considered as having more honesty than plainer men; effort and ability were thought

to be the reasons for their success. Attractive female executives were considered to have less honesty 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 honesty and to be more capable than the attractive female

executives.

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

(女性的) and an attractive man more masculine (男性的) 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. Anne Bowman 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 completely defeated unattractive men, but the woman who had

been ranked most attractive always received the fewest votes.
