So far in this series about the book Merchants of Doubt, we’ve seen (in part 1) that it’s surprisingly hard to divine what the authors (Naomi Oreskes and Erik Conway) are actually trying to tell us, and that this lack of clarity matches their own definition of “bad science”. In part 2, investigating the claim in their subtitle, that a “handful of scientists obscured the truth on issues from tobacco smoke to global warming”, we found that the link between the scientists identified as “the Handful” and the tobacco issue was practically non-existent. We also saw that the claim of “obscuring the truth” rests on the premise that they were contradicting a scientific consensus, and that they haven’t documented even that. The Handful’s activity in the climate change controversy as chronicled in Merchants of Doubt happened during a period when there was no consensus according to Oreskes and Conway themselves.
In this part, I am going to tackle claims 2 and 3 both. As before, the claims are are not direct quotes, but educated guesses about what they mean, since there are no clear conclusions to quote. But I have tried to extract what seems to be implied or what the readers of the book seem to believe are its main messages.
Claim 2: In each case, the deliberate purpose of the Handful was to defend the “offending substance” (tobacco, CO2, acid rain, etc).
This is about the motivation of the players, and it’s hard to ascertain what people’s motivations are without asking them. And asking them is expressly what Oreskes and Conway have not done. I will hazard a guess that, if asked, they would have said they were mostly trying to defend good science and rational science-based political decision-making.
