I personally have noticed that even well educated individuals can utterly fail to properly process known facts.  Individuals who reject the global warming issues are a wonderful example.  They reject the overwhelming evidence.  I have an acquaintance who was a electronic engineer before retirement.  His father was forced to be a union member and evidently the union bosses may have been corrupt.  The father’s views about unions imparted the son to be anti union, anti progressive and pro Republican.  This person vehemently denies that global warming is occurring.  An indicator of this behavior is the process that these people seem to cherry pick their “facts” to support their prejudice political views.
