Thank you for your question. It's an important question.
There are two aspects to that issue. One is that our scientists, while they are in universities in the academic community, learn a set of scientific values, which we all learned. But within government, of course, we have a set of democratic values as well, and you have to recognize that you're civil servants and there are certain aspects of behaviour that civil servants have to conform with to respect those values.
First of all, we encourage and expect our research scientists to publish in the scientific literature. That is an expectation, and in fact we judge them and promote them based on those publications in part. So we do not try to stop them or in any way hamper them from doing that.
We do, however, review their publications and the language in them to ensure that there aren't statements such as, “the federal government ought to do this”, or that they inappropriately step out of their role as public servants.
