(and using what else but climate change as the primary example)
Better scientific policy decisions start with knowing facts from values
phys.org, Aug 2013
When gathering public input on policy questions, scientists can speak with authority about facts, but must remember that everyone is an expert when it comes to values.
"Using climate change as an example, a scientist could say, 'The climate is changing.' That's a fact that can be checked," said Thomas Dietz, a member of the MSU Center for Systems Integration and Sustainability (CSIS) and professor of sociology, environmental science and policy, and animal studies.
"But if a scientist says, 'We need to take these actions to halt climate change because it's affecting what people care about,' that's a value. And scientists have no more authority to speak about values than anyone else. Everyone is qualified to speak about values."
