In general when the stakes are higher and the ambiguity of outcome is less clear, secondary signals become more important.

Concretely: I don't give a shit if my housecleaner doesn't make their own bed as long as they make mine; the outcome I need is easy to verify and the stakes are fairly low so the secondary signal doesn't matter very much. Conversely, I care a lot if the therapist I'm relying on to help me manage my depression is visibly unable to manage their own; the outcome I need has a slow feedback loop and the stakes are high so I'm much more likely to rely on secondary signals like "is this person able to manage their own mood successfully?"
