I guess you have me on numbers but I speak more in terms of influence.
Thanks to Dawkins, the public awareness of science proceeds very much with antitheist influence. Dawkins advocates certain influential physicists and Carroll is an influential string theorist.
So you have no evidence to back up your claim then Vlad.
And I think you are way off the mark. I know you are obsessed by Dawkins, but he isn't really known these days as a scientist at all. And actually I doubt that when he was engaged in his ground breaking evolutionary research that he was 'motivated by anti theism'.
And you pick Carroll out the air - why? Might it be because he is known to be an atheist, rather than because he is a particularly prominent scientist, which he isn't.
Unsurprisingly given my line of work I do understand the motivations of research scientists, including some rather well known ones, because I know them and have talked to them. I'd categorise motivation in three areas, two principled and one pragmatic.
The principled motivations are:
1. A desire to increase knowledge, to find out new things, to follow our natural tendencies to be inquisitive.
2. To improve society, for example by striving to develop new treatments for disease or new ways to generate energy or to create new and better technologies.
In my area people tend to be motivated by a combination of these, as my area involves 'blue skies' investigative science and also more applied science. In some other areas, e.g. my colleagues involved in astronomy or particle physics the motivation is more the first one.
And the pragmatic - effectively I have an aptitude for science and I can make a decent career out of it and it helps to pay the bills and ensures I have a secure future.
I'd categorise my motivations as a mixture of all three. What I am not motivated by is anti-theism, indeed I don't see myself as an anti-theist, but if you wish to categorise me as such I think my motivations in that area come from an interest in ethics and philosophy, not my profession as a scientist.
