Abstract

It is impossible to make sense of persistent controversy over certain forms of decision-relevant science without understanding what happens in the vastly greater number of cases in which members of the public converge on the best available evidence without misadventure. In order to live well — or just to live, period — individuals must make use of much more scientific information than any (including a scientist) is in a position to comprehend or verify for him- or herself. They achieve this feat not by acquiring even a rudimentary level of expertise in any of the myriad forms of science essential to their well-being but rather by becoming experts at recognizing what science knows — at identifying who knows what about what, at distinguishing the currency of genuine scientific understanding from the multiplicity of counterfeit alternatives. Their rational recognition of valid science, moreover, is guided by recourse to cues that pervade their everyday interactions with other non-experts, whose own behavior convincingly vouches for the reliability of whatever scientific knowledge their own actions depend on. Cases of persistent controversy over decision-relevance science don’t stem from defects in public science comprehension; they are not a result of the failure of scientists to clearly communicate their own technical knowledge; nor are they convincingly attributable to orchestrated deception, as treacherous as such behavior genuinely is. Rather such disputes are a consequence of one or another form of disruption to the system of conventions that normally enable individuals to recognize valid science despite their inability to understand it. To preempt such disruptions and to repair them when they occur, science must form a complete understanding of the ordinary processes of science recognition, and democratic societies must organize themselves to use what science knows about how ordinary members of the public come to recognize what is known to science.
