We often assume the person blocking us needs more information. So we build a better deck, find one more statistic, rehearse a sharper case.
But most people who've decided something isn't a priority aren't under-informed. They're protecting something — a deadline, a budget, a promise they've already made to someone upstairs. More information doesn't move them, because information was never the obstacle.
What I've found works better: before making your case, ask one question. "What would this need to not put at risk for you?"
It changes the conversation from you versus them to both of you versus the problem. Sometimes the answer tells you exactly how to shape your proposal. Sometimes it tells you this isn't the moment, which is also worth knowing before you spend your credibility.
Try it this week and report back. I want to hear what the immovable people in your world are protecting.
