This is a fascinating article by Linda Case on Negativity Bias and how it probably also applies to dogs. This article helps support the need for positive reinforcement based training!
Negativity bias – We all suffer from it.
This is the phenomenon in which we naturally pay more attention to and give more weight to negative information and experiences compared with those that are positive. It is this particular cognitive bias that causes us to be more hurt or discouraged by insults or criticism than we are pleased or encouraged by compliments and shining reviews.
It’s hardwired: We cannot easily escape negativity bias. Research studies have shown that the human brain actually experiences stronger neural activity when reacting to negative information compared with when we are given positive information. As a result unpleasant experiences are inevitably more memorable to us than are pleasurable ones.
Why do we have it? Our negativity bias is thought to have evolved as a method for keeping ourselves and those we love out of harm’s way. Think about it like this – your chances of survival are greater if you have a natural tendency to pay more attention to things that may be harmful to you, than if you exist with a more rose-colored view of the world and attend more readily to things that are pleasurable and harmless. Missing the lethal stuff can be, well, lethal (which means that you did not stay around long enough to reproduce and pass along your rosy view of the world to your offspring). In addition to wreaking havoc on our self-esteem, the negativity bias helps to explain why humans love to gossip and why we have a tendency to remember (and sometimes repeat) negative information about others.
