The psychological and scientific study of laughter has recently taken a turn for the serious. Evolutionary theory argues that any behaviour as universal as laughter must have some solemn survival purpose. And laughter has such profound effects on people鈥檚 brain and mind that it is now being seriously deployed to assist those suffering bereavement, having surgery, and even fertility treatment. Could further understanding of the function laughter served become a weapon in our armoury of persuasion and manipulation of others?

A recent study by the Universities of Kent and Liverpool revealed that laughter acts as a social lubricant and increases altruism towards strangers. Mark van Vugt, Professor of Social Psychology and a member of the University of Kent鈥檚 Centre for the Study of Group Processes explains how this theory was tested.
