Confirmation bias is the tendency for people with strong prior beliefs, when confronted with a choice, to make their decisions based on assumptions they’ve already made.

Explanation:

Confirmation bias is a tendency in human behavior to unknowingly be selectively aware of information that confirms our own perceptions. Confirmation bias is a type of cognitive bias.

If you have a negative self-image, you tend to get stuck on criticism and not hear praise. Scientific researchers, too, tend to be selectively aware of research results that are consistent with their own theory and unconsciously ignore those that contradict it. A confirmation bias risks leading to a superstition on personal opinions, while rebuttal and alternative sources are ignored. This can lead to disastrously wrong decisions, especially in scientific, political and military contexts.
