Emotional outbursts are much easier and more immediately satisfying.

Yep. instant gratification is the name of the game these days.

Seriously though outbursts can clear everything out so that a solution can then be focused on, as long as the outburst didn't trigger everyone else to have opposing tantrums and escalate into world war x_x

Perhaps. But I still think that there is more potential damage than upside. All parties stepping away and clearing heads means part of the processing is already done and there is less chance for doubling down on inflicting pain.
