When presenting evidence to support decisions in risk communication, what is most effective?

• A. Share evidence publicly and explain its relevance.
• B. Share only conclusions without data.
• C. Rely on intuition rather than data.
• D. Provide anecdotes without metrics.

Answer: (A)

Presenting evidence in risk communication should center on transparency: make the data and how it’s used accessible and explain why it matters for the decision. Sharing evidence publicly and connecting it to the decision helps people see what the risk estimate is, how confident we are, what assumptions were made, and what actions are recommended as a result. This approach builds trust, invites scrutiny, and reduces misinterpretation by showing the actual data behind the conclusion and the logic that links it to outcomes. It also makes it easier for diverse audiences to understand the implications and to weigh trade-offs.

Providing only conclusions without data leaves people guessing about the strength of the evidence. Relying on intuition bypasses systematic, data-driven reasoning and can introduce bias. Anecdotes without metrics emphasize stories over representative evidence and can mislead about the true level of risk or certainty.
