Are you altruistic? It may have to do with the size of your TPJ (part of brain that determines empathy)

5 years ago

Although altruism is often a  trait in those who are truly spiritual/religious, it's certainly not exclusive to those folks. (There are plenty of incredibly generous people who would describe themselves as agnostic or atheist.) 

So if altruism isn't tied to one's beliefs, does that mean it's tied to something physical? Scientists now believe it could be.

A new study has found that the size of one's temporoparietal junction (TPJ) in the right hemisphere of the brain may play a major role. The TPJ is involved with empathy - our ability to understand the intents and beliefs of others. 

In a new study that used brain imaging scans, researchers found that subjects who were more generous to their anonymous partners (in a game) had a larger TPJ. In addition, during tough decisions, activity in the TPJ increased. 

Here's the study:
