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."
