Bias in the exchange of arguments: the case of scientists' evaluation of lay viewpoints- Public Understanding of Science

Note: a bit off topic but the last point taken:

"Abstract

Most perspectives on public participation share the notion that dialogues should be open, allowing participants to articulate and evaluate different views and knowledge claims. We hypothesize that participants' evaluation of claims may be biased because participants have a preference for a particular type or source of a claim. This would hamper an open dialogue.....

Contrary to our expectation, scientists evaluated claims of the public more positively than claims of experts."
