perfect programmer syndrome

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}."
