In our view, the fact that so many scientists agree so closely about the [causes of the] earth’s warming is, itself, evidence of a lack of evidence for [human caused] global warming. – D. Ryan Brumberg and Matthew Brumberg

Among the best indirect indicators available to nonexperts is the overwhelming numbers of scientists testifying to anthropogenic climate change. Yet the evidential significance of such clear numbers turns substantially on our nonexpert assessment of these scientists’ trustworthiness. Absent trust, even without active distrust, the numbers’ evidential weight drops considerably. – Ben Almassi

If deference to the authoritative opinions of experts is essential to our rationality and knowledge, and if that deference unavoidably rests on trust, not only in the competence, but also in the epistemic and ethical characters of our experts–then it is high time that we get to work on the ethics of expertise. Indeed, it is past time. – John Hardwig
