You sabotage yourself to protect your ego.

A 1978 study found that participants chose to consume performance-inhibiting drugs when they were anxious about an upcoming test.

By creating obstacles for yourself, you ensure an external excuse for potential failure. If you succeed, you are a genius; if you fail, you have a ready-made reason that isn't your own ability.

You prefer failure to the threat of incompetence.

Confidence
Well replicated
