Egoism and narcissism appear to be on the rise in our society, while empathy is on the decline. And yet, the ability to put ourselves in other people's shoes is extremely important for our coexistence. Scientists have discovered that our own feelings can distort our capacity for empathy. This emotionally driven egocentricity is recognized and corrected by the brain. When, however, the right supramarginal gyrus doesn't function properly or when we have to make particularly quick decisions, our empathy is severely limited.
