t lights up when we … why people are always thinking about themselves. There is a certain area of the brain (MPFC/DA 10) that is sort of the “default network” area. It gets activated when the brain is at rest and not engaged in external demands. Their imaging work confirmed that it is also the same area that lights up when we think about ourselves.
So the research supports this truth. We talk about ourselves more than anything else. We use our own experiences to make assumptions about other people. And our brain is wired to think about ourselves when it’s not engaged in other external demands.
