Men

   It has been noted that men rate good liars as having leadership.  What they are actually measuring is controlled schizophrenia.  In a fight schizophrenia can be an asset, the ability to turn off one's brain and fight without regard to personal safety or injury increases the chance of winning the confrontation.  The ability to lie well requires shutting off the brain ad creating a false world  in which one can simulate belief.  It takes control to lie well as well as disconnecting unnecessary parts of the brain dealing with guilt or fear.  There is a similarity to fighting skills.  The controlled nature of lying becomes a substitute for the controlled aggression of fighting.
    It is not particularly accurate in determining the ability to fight well.  It does not show the ability to think quickly when in anger or the ability to focus on  goals, nor does it show innate fighting skills.  It is an expedient shorthand which is fairly inadequate.  It tells something when the total of information is nothing.  Unfortunately, in realms such as politics it is often all the information available and leas to dreadful voting decisions.
   In war, when in battle, soldiers are probably almost all psychotic, it is necessary to survive.  A battle requires focusing on one enemy to kill while ignoring others who are trying to kill the soldier.  That deliberate ignoring of information is psychosis.  The only way to survive is to ill the enemy, but thah means sequentially killing aggressors while exposing oneself to getting killed, insanity is an aide in those circumstances.
   What also happens to soldiers is the lack of patterning to the battle around them.  The brain functions by having a pattern to the world which it updates.  In a battle, that complete lack of pattern causes the brain to doubt its model while producing no alternative model.  The brain begins a process of distrusting its own function,it looses the feedback loop of making small changes and adjusting progressively to new information.  The soldier develops the thousand yard stare of unfocused eyes when the brain cannot make the continuous adjustments needed to bring the eyes into focus.  Thee is also a tendency to be aggressively defensive and hyper vigilant since the brain can no longer tell the seriousness of any threat and it assumes any contact is a dangerous threat.
   Schizophrenia is an asset in most sports, it enables the brain to have a more fluid flow of complex information.  When dealing with a complex sport, like hockey, the brain must be fluid and flexible.  A player will have to track the movement of players on both teams, the goalie and the puck.  Derailed thinking is the only way to do that in the short time allowed for decisions.  The brain must track the different variables in parallel and then mix and match them quickly to develop a pattern of the play and then determine how to influence it.  Professional athletes have high rates of schizophrenia to allow for that fluid processing.  They also tend to be schizophrenic because schizophrenia produces the mind set of the importance to succeed and be known, when other people say the work and pain are not worth it, schizophrenics will continue because they need to be famous to determine they are n control, the brain is testing for its own sanity.
   This is true also of explorers and participants on extreme events, they need to do something to succeed to prove they are functioning.
