Bias blind spot

from Wikipedia, the free encyclopedia

The bias blind spot (German for "distortion blindness") describes a cognitive distortion (cognitive bias): the tendency to consider oneself unaffected. The essential feature of this distortion is the person's own perception of the objectivity on the part of the person concerned, i.e. to believe that one is completely free or at least free of influences and such phenomena only apply to others. While motivated cognition can have meaningful functions in everyday life, such as maintaining or promoting self-esteem , in science it forms an obstacle to the generation and dissemination of valid knowledge.

The name was coined by Emily Pronin , a social psychologist in the Department of Psychology at Princeton University , along with her colleagues Daniel Lin and Lee Ross . The underlying English expression bias blind spot , analogous to the optical blind spot of the eye, indicates such a misconception.

causes

Bias blind spot can be caused by a variety of other cognitive distortions and self-delusions .

The own concern escapes the discovery due to a distorted perception, but probably not with regard to other people in comparable situations. The related process is called "introspective illusion". Various German studies have also confirmed this phenomenon in the medical field.

distribution

Most people seem to have distortion blindness. In a sample of more than 600 United States residents, more than 85% believed they were less biased than the average American . Only one participant believed they were more biased than the average. Respondents varied with regard to the extent of the blind spot bias , but there were stable individual differences that were measurable.
