I am intelligent and make good decisions.

You will never have an accurate record of your own judgement, because the good calls leave no trace. The road you did not take, the offer you turned down, the argument you did not start at eleven at night. None of them generate a story. Only the wrong turn gets remembered, and it gets remembered vividly, in the tone of voice you reserve for your own mistakes.

Drive a hundred junctions correctly and one badly and it is the one you will replay in bed. That ratio is not evidence about you. It is just how memory files things.
