Finally, let me speak up for scientists. In my experience, the vast majority of scientists are honest, sometimes slightly nerdish people who are grateful to be able to work on something about which they have a passionate interest. Scientists can be arrogant: but overall they do not deceive themselves, or the public.
From an article written by Philip Strange. I’m not sure about slightly nerdy, but there is a lot of variation even among people studying science, and I’m probably at the nerdy end of the spectrum.
