Innate ‘Sense Of Justice’ Neural Circuitry Built Into The Brain

A new study from the Karolinska Institute and Stockholm School of Economics shows that the brain has built-in mechanisms that trigger an automatic reaction to someone who refuses to share. In the study publishing next week in the online open access journal PLoS Biology, the subjects' sense of justice was challenged in a two-player monetary fairness gam
