So when is rationality relevant? Always! It’s literally the science of how to make your life better / achieving your values.
Sometimes science isn’t helpful or useful. The science of how music works may be totally irrelevant to actual musicians.
If you think of instrumental rationality of the science of how to win, then necessarily it entails considering things like how to setup your environment, unthinking habits, how to “hack” into your psyche/emotions.
It’s an empirical question when and whether these things are very useful; my post gives cases in which they are, and in which they aren’t.
