I'm not going to take the inter-generational warfare bait :). But I agree with what I think is your main point.
My natural tendency is to want consensus. I think that's worth attempting within a reasonable time-frame. But after some discussion, eventually a decision needs to be made.
Many decisions are reversible at a very small cost. Sometimes making the wrong decision, soon, then correcting it, soon, wastes no more time and resources than not deciding at all. Sometimes it's even preferable for morale.
Having everyone row together in the wrong direction, then change course, isn't ideal. But at least everyone is rowing in the same direction and feels like a real team. Often that's better than sitting in middle of the ocean, oars in the water, debating and going nowhere.
But as with most advice I offer unsolicited, I'm going to waffle and say, "it depends on the situation". :)
Writing about biology, finance, or geology? Shrug.
Dumb filtering is bad enough when used by smart people with good intent.
