In a study, a group of college students was asked to view different advertisements for a certain product. After having seen the ads, the men in the group said that they were more likely to buy the product than they were before they saw the ads, and the women said that they were not more or less likely to buy the product than before they saw the ads. Women, then, are less easily influenced by advertisements than are men.
