There may be a place for those people — i.e. where a fast confident decision is actually better than a thoroughly discussed ‘correct’ decision.

Those people, in my experience, are usually pretty comfortable taking big risks (on their spotty information), which can be useful.

But if you’re the second kind of person, working with the first kind would be infuriating. So if long term happiness was your goal you’d probably want to work for organisations that encourage careful collaborative decision making.

Basically, if you’ve recognised in yourself that you don’t like these people, avoid them (and places they’d be drawn to).

I can’t think of any way you could ‘bring them down to size’, etc, that wouldn’t just bring more pain.
