Yes, it has come to this : the prestigious scientific journal Nature mentions, by name, Limbaugh, Fox News, Glenn Beck and Sarah Palin, as concrete threats to the American scientific complex, and hence threats to the future prosperity of this country.
I almost don't want to weigh in on this ( all sides have committed errors ), but the fact that one of the most prestigious scientific journals is listing enemies by name clearly signifies at least one thing : the relationship between science and society is deteriorating.
Some time in the past, I'm told, Americans respected science. It let us end WWII brutally and concisely, and got us to the moon before the Soviets. What is different today, that the public no longer respects scientific evidence for making informed policy decisions ?
It also seems to me that complaints about liberal bias in science have a very simple solution. If you think science is too liberal, get off your political stage, get a doctorate from a reputable research institute, and do some quality peer reviewed science of your own. Science doesn't really care that much about your politics. One of my more excellent mentors, who taught me about the Fourier transform and various image processing algorithms, was politically conservative. This was absolutely no barrier to his ongoing stem cell research. So, my more conservative friends, rather than complaining about the inherent liberal bias in science, why don't you come on over and learn some rigorous scientific reason and help us out.
p.s. : the comments on that Nature opinion piece get, predictably, a little crazy. "La République n'a pas besoin de savants, uniquement d'équité" .. oh dear, has it really come to this again ?
