It is a skill to genuinely or convincingly look past your own lack of competence.

I think that's more about leadership. For whatever reason "we" seem geared to follow people who pretend to know their way forward even when they're completely lost, perhaps even more lost than average.

Like Teddy Roosevelt said - 'Speak loudly, aggressively flail about, and you'll go far.' Or something like that.

I wonder if that's a case where folks in leadership feel like their job is to show confidence, provide direction, and they still maybe know they don't know enough (I mean who does...) and they still make the call (right or wrong).

Perhaps more of a poor leadership thing we observe.

Have you considered that you might not be able to gauge peoples competence and knowledge accurately? Statistically, if you are observing so manly outliers that is likely to be the case. Hope this helps!
