What does public sociology have to say about sociologists who are ‘merchants of doubt’? This is the question I’m slightly obsessing over after discovering that Peter Berger, famous for his work on social construction and the sociology of religion, worked as a consultant for the tobacco industry. As Source Watch details, he was tasked with establishing that “anti-smoking activists have a special agenda which serves their own purposes, but not necessarily the majority of nonsmokers”:
He served as a Tobacco Institute consultant. While at Boston College, Berger, (as quoted in tobacco industry newsletter “The Tobacco Observer,”) described tobacco control proponents as “fanatical.” Berger attended Philip Morris executive meetings  and participated in the multinational tobacco industry’s Social Costs/Social Values Project, created to refute the social costs theory of smoking and to help reverse declining social acceptability of smoking. He was a contributing author to the industry-financed book Smoking and Society, edited by another tobacco industry consultant, Robert Tollison.
This is critical sociology deployed on behalf of the powerful: pulling back the veil on a group pursuing an ideational agenda and claiming they act out of sectional interests. What other examples are there of prominent sociologists acting in this capacity? How should these cases inform our conception of public sociology?
