Binary people are funny. Everything is always 1 or 0, nothing is ever undefined and the idea to have different levels of certainty never occurs to them.

Not what I was conveying. There's a place for nuance, but from my experience in practice, being able to be decisive is more useful than contemplating and questioning. Not to say I avoid the latter (what are we doing right now?) or that it isn't useful, but the times at which it's really needed are few and far between
