Scientists Know Better Than You--Even When They're Wrong [Features]

If you take scientists at their word, human-induced climate change is well underway, evolution accounts for the diversity of life on Earth and vaccines do not cause autism. But the collective expertise of thousands of researchers barely registers with global warming skeptics, creationist movie producers and distrustful parents. Why is scientific authority under fire from so many corners? Sociologist Harry Collins thinks part of the answer lies in a misunderstanding of expertise itself. Like Jane Goodall living among the chimps, Collins, a professor at Cardiff University in Wales, has spent 30 years observing physicists who study gravitational wave detection--the search for faint ripples in the fabric of spacetime. He's learned the hard way about the work that goes into acquiring specialized scientific knowledge. In a recent book, Rethinking Expertise, he says that what bridges the gap--and what keeps science working--is something called "interactional expertise". Collins spoke recently with ScientificAmerican.com about his view of expertise; what follows is an edited transcript of that interview.
How did we get to the point where scientific authority is so easily challenged? [More]
