Women are lied to significantly more than men are when it comes to negotiations. Those were the findings of a University of California, Berkeley study, which involved MBA students vying for the best deal in a simulated real estate negotiation.

"What we found is that when people are representing the buyer and negotiating with a female agent representing the seller they were actually more likely to enter into a deal and they did so by deceiving her. And so we found that they were four times as likely to blatantly lie to a female as they were to a male. And when we looked just at the men who were acting as the buyer’s agents, they were eight times more likely to lie to a female than they were to a male."

Lead author Laura Kray says part of the reason for this is that women are perceived to be less competent, but warmer than men in negotiations.

"If people perceive women as less competent then it’s going to be easier to get away with a lie. In negotiations people get into what we call an opportunistic mindset and where they seize upon it."
