Negativity Bias

A negativity bias is a cognitive bias that contributes to the tendency to notice and dwell on negative information while neglecting positive information.

What Is a Negativity Bias?

Negativity bias can affect decisions, emotions, and even the ability to take in information. Several studies have shown that humans in general tend to attend more readily to negative information. Thus, a person is more likely to notice a car wreck on the side of the freeway than  a person helping someone fix a flat tire on the other side of the road. Negativity bias also helps to explain why people tend to be more bothered by criticisms than they are flattered by compliments, and why people tend to dwell more on mean gestures than they relish in kind ones.

Why Does the Negativity Bias Exist?

Researchers have not identified conclusively why the negativity bias exists. While some researchers argue that the negativity bias is an innate mechanism, others emphasize the primacy of cultural norms in increasing the likelihood that people notice negative information. Some potential reasons for the negativity bias include:

  • Negative information tends to be more novel and jarring. A loud car wreck is much more likely to get your attention than, for example, the silent assistance one person provides to another.
  • Taking in negative information–particularly negative information about threatening scenarios–is critical for survival, health, and social interactions.
  • People tend to more readily remember negative information than positive information. Thus the negativity bias could be a product of memory processing rather than cognitive functions that occur at the moment a person takes in information.

Negativity Bias and Mental Health

The implications of the negativity bias for mental health are clear and striking. Rumination–the process of lingering on information–over negative information can increase the likelihood that a person develops depression. People who do not notice positive stimuli or who tend to talk about negative occurrences more readily than positive ones are more likely to struggle with unhappiness, depression, and anxiety. A person’s negativity bias can partially be a product of personality and deliberate thought retraining, and people who do not have a strong negativity bias tend to be happier, better-adjusted, and more well-liked.

    Negativity bias is interesting and i think it is one of my problems…
    and here is how i got into it : )
    i feel people, including myself, either are in denial about world problems or have been… and that that is why so many world problems are not addressed or taken care of… solved. …so i am one of those people who WAS in denial about world problems… i cannot ignore them any longer…

    so what is the difference between negativity bias and awareness of reality?

    Same here, lala. Not long ago, my therapist asked me, “Do you want to be happy?” I replied, “Yes, but not at the expense of truth. If there are serious problems in the world that could be solved if more people cared, and those problems continue unsolved, what is there to be happy about by ignoring the unnecessary suffering going on all around us?”
    I think it’s somewhat tragic when even mental health professionals have become so callous to reality that all they can do is focus on how to help other people be well by teaching other people to ignore these big, unnecessary problems and just to focus on ‘little pink bubbles of personal happiness’.
