perfect programmer syndrome

( n.)

   Arrogance;  the egotistical conviction that one is above normal human
   error. Most frequently found among programmers of some native ability
   but  relatively  little  experience  (especially new graduates; their
   perceptions may be distorted by a history of excellent performance at
   solving  {toy  problem}s). "Of course my program is correct, there is
   no need to test it." "Yes, I can see there may be a problem here, but
   I'll never type rm -r / while in {root mode}."
