What is self-serving bias in psychology?

  • This refers to a cognitive bias that causes people to overestimate their worth while underestimating their unfavourable drawbacks.
  • So, they attribute positive events in their lives to their own high capability and character and link negative events to external factors like bad luck or the unfavourable actions of other people.
  • Self-serving bias helps people to protect their ego from negative feedback that could damage their self-worth.
  • The existence of the bias was first proposed by Dale Miller and Michael Ross in their 1975 paper “Self-serving biases in the attribution of causality”.
