‘Don’t trust men with wider faces’
For the study, a team of psychologists at the University of St. Andrews invited a group of men to play a computerised game for money. The game offered players chances to trust other participants, but also opportunities to exploit them.
During the game a participant was shown an expressionless photo of a fellow player’s face at the start of each game. The participant had then to decide whether to take an immediate pay-off or entrust the money to the person they saw — who, in turn, could decide either to cooperate, and help both players make more money, or take the cash and run.
Lead researcher Michael Stirrat set up the games to investigate whether he could find any measurable relationship between perceptions of trustworthiness from perceptions and behaviour.    —PTI
