I'd be plenty happy if I could keep playing scientists and cops for the rest of my career.
If two scientists are giving their papers at a symposium, and one of them is just naturally better at talking to the public or talking to a group of people, that scientist is liable to get more attention - in fact, I'm told that they do get more attention - than the one who's a little more stiff about it. Well, that's not good for science.
If scientists could communicate more in their own voices - in a familiar tone, with a less specialized vocabulary - would a wide range of people understand them better? Would their work be better understood by the general public, policy-makers, funders, and, even in some cases, other scientists?
I think it's important for scientists to speak in their own voices and not just be mediated by journalists or others speaking for them.
Whenever I think of how much pleasure I have interviewing scientists, I remember that they're having the real fun in actually being able to do the science.
We're highly social animals - I'm told by scientists that what makes us different from other animals is an acute social awareness, which is what has made us so successful.
