The interdisciplinary field of science, technology, and society (STS) was launched in the 1980s to challenge perceived overreach of scientific authority. As STS scholars honed their critical tools, however, assaults on scientific authority gradually became associated with the same conservative, rapaciously capitalist interests the field of STS had first set out to critique. Championing scientific dissent, possibly undercutting scientists' expertise, and emphasizing contingencies in the scientific process became problematic for STS scholars to pursue. The subsequent reckoning has motivated Lynch to develop tools for determining when minority scientific positions should and should not be taken seriously. Lynch's argument follows Bruno Latour, whose Down to Earth (CH, May'19, 56-3759) attempted to put STS on a new footing. The result is a thorough and thoughtful overview of the past half-century of thinking on scientific consensus and dissent, articulated through cases ranging from dietary science to climate change. The book proposes useful conceptual tools to help sort the minority wheat from the minority chaff. Scholars in STS and adjacent fields will find this a rewarding and provocative read… Recommended.
