In groups with reasonable folk working with aligned incentives, the biggest source of disagreement tends to be a lack of context.
Investing a bit of time upfront to share context – personal context early in the relationship and context about the situation and the problems being solved otherwise – saves hours and hours in time spent in disagreement otherwise.
Even with the best of intentions, it is hard for folks to meaningfully contribute without understanding the full picture.
And, we’re best served when we remind ourselves that we must go slow… to go fast.
