Strong avoidance

   The brain functions with multiple paths of processing working in parallel.  In order to adapt it moves its primary focus from one parallel path to another.  That is the basic formation of derailment, the brain shifts and processes information from a slightly skewed perspective.  If that new perspective provides something interesting, the brain focuses onto it and tries to search for additional connections that would add to it.  If it is judged useless, the brain rejects it and shifts position again to try to produce useful processing.
   Diagnosable schizophrenia is the brain skipping too far or too frequently.  The brain can spontaneously have erratic skipping, which can be debilitating in its total disruption of a person's function.  However, people can be driven to insanity by being taught to panic, usually by abusive parents.   This typically takes the form of abusive intrusion into innocuous  actions of the child, You shouldn't be putting that much crayon on the paper, you should be using the colored pencils, instead.  The brain can also not learn how to deal with any stress by failed parenting examples, We'll just go to the front of the line, these people aren't as busy as us.  The parent is in a line, feels trapped and panics, at which point the parent teaches the child to panic and be obnoxious.   Truly obnoxious actions can only be stopped by the use of force, unfortunately, law and society discourage and prevent that solution.
   The person raised in this manner panics  at any attempt to self reflect.  The learned panic of never questioning one's actions leads to the need to produce elaborate cover explanations whenever the person is forced to reconsider actions, You said yesterday, that you would finish in two weeks, now you say it will take six weeks.  That was a planning estimate, this is an operational estimate.  They will create new words, abuse current definitions and insist on the acceptance of only there explanation.  The alternative is they will just say that it never happened.
     That constant need to avoid reviewing is related to the complexity of review.  The person must hold the action under consideration in mind and then look at other alternate choices, memories of other experiences and consideration of what other people might do.  If the brain is panicking, it skips, and if it skips it loses track of which action; remembering, recreating, comparison, it is performing.  The brain senses an overload of activity and takes an escape route, which can involve a descent into fantasy.
   The extremes to which a person will go to avoid admitting error can be stupefying; You killed five people,  You don't know that, they might have died anyway.  The first time the person is caught in an area where they have never been challenged, they might almost admit error, but if they are repeated subjected to criticism they will develop increasingly complex avoidance schemes and evasions, their brain essentially develops a protective crust through which reality cannot penetrate.
   The whole process might be somewhat comical accept that these same individuals push themselves into positions of  authority out of their own panic; They cannot be subordinates because that exposes them to criticism which would make them look at themselves which would make their brain tear itself apart in panic.   So they endeavor to place themselves in positions of authority where they criticize others and avoid having to consider their own actions.  They are aided in this by all the other poorly socialized who have already pushed themselves into supervisory positions, they are all friends because they all know they should never say anything that will force reflection, they can attack and damage others who are not in the group but they are protective of each other in a mutual pact of insanity.
   If they cannot supervise others, at least hey can abuse their own children and generally they do, repeating the whole process for another generation.
