Mind - Some Protect the Ego by Working on Their Excuses Early - NYTimes.com: "Psychologists have studied this sort of behavior since at least 1978, when Steven Berglas and Edward E. Jones used the phrase “self-handicapping” to describe students in a study who chose to take a drug that they were told would inhibit their performance on an exam (the drug was actually inert).
The urge goes well beyond a mere lowering of expectations, and it has more to do with protecting self-image than with psychological conflicts rooted in early development, in the Freudian sense. Recent research has helped clarify not just who is prone to self-handicapping but also its consequences — and its possible benefits."
