The level of concern and anxiety among scientists - and I guess I'd say the science-friendly public - about the place of science in society in government, has gone beyond concern to anxiety.

There is a sense that science and politics are incompatible. I don't think so at all. I think it's important that scientists take great pains to make sure that ideology and personal bias and wishful thinking do not contaminate the collection and analysis and evidence.

We know Thomas Jefferson and Benjamin Franklin as politicians, but they felt that science was something everyone should have a knowledge of.

There seems to be a concern about whether the public appreciation of science has eroded to a point where it has removed science from public debate and public decision making. Whether the public has come to regard evidence as optional.
