According to a study by the University of Florida, people who are intelligent earn more money in their lifetime than people who are simply self-confident or attractive. While the study admits that both play an important part in the workplace, brains earn people more money than beauty.
The results of the study came from a survey that was taken by 191 women and men between the ages of 25 and 75. Intelligence was measured during the survey by having the participants take mental exercises. The self-confidence of the participants was determined by their answers to 15 questions. The purpose of the questionnaire was to determine how the participants cope with different life situations.
