Perhaps from bad decisions? As I stay awake, the quality of my code drops pretty fast, social decisions get worse, I say the wrong thing to people, et cetera.

This is question-begging. 'We get fatigued because we get fatigued.'

  • That's conflating two different senses of fatigue. "We feel tired to prevent us from making mistakes when we have been awake a long time."

    That separation of the different senses of fatigue is the core of the article. Fatigue is both a feeling and a state, which we confuse because they are connected. But you can give someone drugs, like diphenhydramine or caffeine, which change the feeling of fatigue without changing the underlying state which that feeling normally reflects.
