Testosterone the Truth Drug

Testosterone is usually associated with risky and aggressive behaviour, muscle-building and male sexual characteristics, but now it seems it may also promote honesty.

Researchers at the University of Bonn recruited 91 healthy men, and treated 46 with testosterone gel by applying it to their skin. The other men were given a placebo gel. The men then played a game of dice for money, where they had the opportunity to cheat.

Through statistical analysis of the subjects’ self-reported scores, the researchers were able to determine which men had lied about their scores for more money. The group of men with elevated testosterone had cheated less often.

The study’s authors speculate this may indicate that testosterone increases feelings of pride and self-worth.
