Negativity bias or Negativity effect — Psychological phenomenon by which humans have a greater recall of unpleasant memories compared with positive memories. (see also actor-observer bias, group attribution error, positivity effect, and negativity effect).

Often we are faced with situations where our intuition misguides us. Cognitive biases are systematic patterns of deviation from norm or rationality in judgment. Many of these biases affect belief formation, business and economic decisions, and human behavior in general.
