As mentioned in part 1 of this series, the book Merchants of Doubt by Naomi Oreskes and Erik Conway focuses on the allegedly sinister actions of a “handful of scientists”. According to the book’s subtitle, these scientists “obscured the truth on issues from tobacco smoke to global warming”. Trying to deduce what this might mean in more specific terms, I wrote:
Obscuring the truth is a somewhat vague concept, but it seems to imply that these scientists been quite influential, and that their communication with the public has been untruthful and probably deliberately deceptive.
So let us assume that they intend to say that a “handful” (presumably three or more) of scientists have “obscured the truth” on both tobacco, climate change and other issues. Tobacco and climate change are by far the most relevant of these. Tobacco, since it’s a well-documented case of deliberate fraud; climate change, since it’s the only one over which there is still a strong active controversy.
To investigate what truth there might be to this, we first need to know who “the handful of scientists” (let’s call them the Handful) are supposed to have been. There is no definitive, exhaustive listing in the book, but the main ones that tend to appear together in different chapters are Fred Seitz, Fred Singer, William Nierenberg and Robert Jastrow. (Since the book mentions a large number of other, less significant characters, it’s a research project in itself to discover who recurs and therefore hard to be absolutely sure who should be included.)
These are my principal findings from studying the book: Given these main “bad guys”, I find that the links between these individuals and the two main issues are weak at best. The link between the Handful and tobacco is practically non-existent. The link between the Handful and climate change is based on old information (only Singer is still living) and has questionable relevance to the current controversy. The idea that they were obscuring the truth about global warming is based primarily on the idea that they were attacking a scientfic consensus, but according to Oreskes and Conway themselves, the period during which they were active hardly overlaps the time during which there has been a consensus.
To get into the specifics, let’s look at each person in turn.
