For many decisions, any amount of thinking is overthinking

A prime example: "What will I order for dinner?" If there's a question among N options, then they appear about equally good according to different criteria. The consequences are minor — the (dis)pleasure of one night's meal. Nobody else is likely to care much about this decision.

There are many decisions like this. The consequences are minor and often difficult/impossible to know to the degree of detail we'd need to distinguish the options without actually selecting an option.

The answer: Any amount of thinking is overthinking. Pick one.
