A person can explain a conclusion accurately and still leave the audience unable to act. The argument may be complete to its maker but incomplete to those who carry different information, incentives, and risks.
When that gap persists, the cost is more than frustration. Good work can be delayed, capital can stay still, and the person who saw the issue clearly may be judged by an outcome they could not move.
The first task is to find where understanding breaks: the claim, the supporting evidence, or the trust needed to rely on it. Only then can the message improve without surrendering its substance.
