Trust can only be rebuilt by honestly prioritizing shared risk reduction.

Evidence

Building the structures of mutual trust that would be required to diminish the urgency of the risk cannot be done by burying one’s head in the sand, still less by encouraging others to do so. It can only be done by focusing more clearly on the scale of the risk itself and establishing a clear mutual understanding of the priority of the need to reduce it over the need to diminish other — often in their own terms equally realistic and indisputably grave — anxieties. — Diego Gambetta, Trust - Making and Breaking Cooperative…, 1269
