The world is filled with overconfident people. Overconfidence leads to malpractice, to fraud, and to broken promises. Overconfidence is arrogance. You don’t want an overconfident surgeon or even an overconfident bus driver. By definition, overconfidence leads to risky behavior and inadequate preparation. But the practice requires us to do our work without becoming attached to the outcome. It’s not overconfidence, it’s a practice of experiments that respect the pitfalls of hubris.
