Peter Hatemi

Dr. Peter Hatemi, a professor at Penn State, stated that conservatives express more Psychoticism, which he defined as " uncooperative, hostile, troublesome, and socially withdrawn, but lack feelings of inferiority and have an absence of anxiety. At the extremes, those scoring high on P are manipulative, tough-minded, and practical." He also claims that the counterparts of these conservatives [the left] is more likely to be altruistic, well socialized, empathic, and conventional.
