Prestige from one field was repeatedly borrowed to contest findings in another

Oreskes and Conway's central figures, Frederick Seitz and S. Fred Singer, built their scientific reputations in physics, Seitz through work connected to the development of the atomic bomb and a term as president of the National Academy of Sciences, not through original research in medicine, public health, or climate science. Yet both men repeatedly testified and published on exactly those unrelated fields, leveraging institutional titles and physics credentials to claim authority they hadn't actually earned through relevant expertise.

The authors argue that this borrowed authority worked precisely because journalists and the public generally assumed scientific credibility transfers across fields, when in reality expertise in one specialized discipline confers no particular authority in another. Media coverage rarely made this distinction clear to audiences.

Takeaway: a scientific credential is not a universal passport, it's earned expertise in one specific field, not a general license to override consensus in every other one.
