Oh, really? Women are perceived as less competent and more gullible than men, so people lie to them more during business transactions. That’s the conclusion of a new study published online this month in Organizational Behavior and Human Decision Processes, in which researchers asked MBA students to pretend they were brokering a real estate deal. When given the option to take advantage of a male or female buyer by fibbing, participants were significantly more likely to lie to female buyers. They also expected women to be warmer, more naive, and less competent than men—a stereotype that may put women at a disadvantage in the business world, Slate reports.
