Carl Jung, a Swiss psychiatrist and psychoanalyst who founded analytical psychology ,stated the shadow to be the unknown dark side of the personality.[6] According to Jung, the shadow, in being instinctive and irrational, is prone to psychological projection, in which a perceived personal inferiority is recognized as a perceived moral deficiency in someone else. These projections insulate and harm individuals by acting as a constantly thickening veil of illusion between the ego and the real world.
