What is Negativity bias?

The negativity bias, also known as the negativity effect, is the notion that, even when of equal intensity, things of a more negative nature have a greater effect on one's psychological state and processes than neutral or positive things. In other words, something very positive will generally have less of an impact on a person's behavior and cognition than something equally emotional but negative. The negativity bias has been investigated within many different domains, including the formation of impressions and general evaluations; attention, learning, and memory; and decision-making and risk considerations.
