Be a man: tell the truth
Higher levels of testosterone have been implicated in some negative qualities associated with men, such as impaired empathy. Recent research, though, is showing some upsides of the same hormone; now, a new study finds that testosterone inhibits lying. Men were given either testosterone or a placebo and were later asked to roll a six-sided die in private, and whatever number the men reported rolling would determine their payoff for the experiment. Men with higher testosterone reported they’d scored payoffs far closer to the rate of probability. While men who were administered the placebo reported rolling the highest payoff 62% of the time, those who were administered testosterone reported rolling the highest payoff just 35% of the time.
