What is; the driving force which blocks out happiness and acceptance from the human mind? As it were, negativity. What makes one oblivious to the ‘good’ things that surround one’s life? What makes one seem to prefer to linger in their own self-pity than try to savour and cultivate the better areas of their lives?
Due to the brain’s “negativity bias”; it is simply built with a greater sensitivity to unpleasant news. The bias is so automatic that it can be detected at the earliest stage of the brain’s information processing.
Why do insults once hurled at us stick inside our skull, sometimes for decades? Why do some people have to work extra hard to ward off depression?
The answer is, for the same reason political smear campaigns outpull positive ones. Nastiness just makes a bigger impact on our brains.
