Men More Prone to Revenge, Study Says

A new study by Nature shows that men are more likely to seek revenge than women. Researchers used MRI brain scans to study subjects viewing wrongdoers given an electric shock and how the subjects' brains responded.

In men, the pleasure areas of the brain responded to the visual stimulus, while in women, it didn't. In an article for the Herald Tribune International, Elisabeth Rosenthal writes:

Men "expressed more desire for revenge and seemed to feel satisfaction when unfair people were given what they perceived as deserved physical punishment," said Dr. Tania Singer, the lead researcher, of the Wellcome Department of Imaging Neuroscience at University College London.
