It’s the tendency to put more attention, value and weight on negative comments and experience than on the positive. It’s human. We seem to be hardwired to do it. Some theorists suggest that our survival depended on it when we were living in primitive times. People who didn’t stay alert for saber-toothed tigers probably didn’t get to see another day.
