Japanese researchers recruited about 100 men to play a trust game using photographs of women. In the game, each man was given 1300 Yen (approx. $13) and asked to rate the attractiveness of each woman as well as how much money they would give them in the trust game. The men were told that the amount of money given would be tripled, and the woman could then choose how to split the money between herself and the man. Unbeknownst to the men, every woman had already chosen in advance to take all of the money, completely stiffing the man. In other words, every woman played the "honey trap."
