One of the most productive things we can do when we disagree with some one is be really clear right off the bat about what we disagree on. I think that disagreement raises people's walls, right in,. sort of raising their defences to such a degree that they start to think in zero sume terms about the other person. It's critical when we can to not extrapolate or over generalize in that way, but instead to have open conversations about what we disagrees about this. And oftentimes starting with that common ground makes discussion of task conflict feel much less dangerous and go much more productively.
