The Image Spot Bias (Blind spot) is a distortion in the context of examinations. This effect is the Tendency, To consider oneself uninfluenced and undistorted in one's perception and judgment. The essential characteristic of this distortion is the perception of objectivity on the part of the person concerned, i.e. the belief that one is completely free or at least freer from distortions and that such phenomena only apply to others. This effect can arise in particular if you believe that you know enough about distortion effects.
