Nice to meet you @scott. I think the advice in this AAAS publication is really helpful. Have you read it yet?
We discuss it in our Mission and Values too:
Scientists in Civic Life by AAAS. The AAAS is the worlds largest association of scientists. They articulate evidence-based guidelines for engaging the public with science, advocating a trust-building model over a “knowledge-deficit” model of engagement. The data clearly indicates that it is not enough to be right, we also have to be trusted.
