<unk>  typing, which combines elements from neuroscience, physiology, and psychology, is a system developed by Jonathan P. Niednagel.  It is based on ideas of the psychological typology of Carl Jung, and the later work by Katharine Cooks Briggs and Isabel Briggs Myers known as the Myers-Briggs<unk> Indicator (MBTI).
What separates<unk>  from Jungian typology, and its offshoots such as the MBTI and Socionics, is its emphasis on mental and motor skills.  Each of the sixteen<unk>  is said to specialize in certain regions of the<unk>  responsible for varying degrees of mental and motor skills.  Niednagel believes<unk>  are inherited, possessing a genetic basis.
Niednagel started to develop<unk>  typing in the 1970s while coaching little league baseball.  He observed that children with similar personalities also had similar motor skills.  Having spent several decades on research, Niednagel's work began to receive more attention in the 1990s, particularly in the arena of professional sports.  Perhaps the most well-known event related to<unk>  typing was Niednagel's prediction in 1998 that Peyton Manning would become a star quarterback in the National Football League (NFL), and that the similarly hyped Ryan Leaf would perform poorly in the league.  His prediction came true as Peyton Manning has become one of football's best quarterbacks while Ryan Leaf is remembered as one of the worst busts in football draft history.
With all the effort and research that Niednagel has put into<unk> , it has not yet been validated through science. It is also uncertain how much application<unk>  has beyond the realm of sports, since the primary difference between<unk>  typing and related typologies is the motor skill emphasis.
