Organized Skepticism. How can the science of tobacco and nicotine serve the public good?

There are almost as many definitions of science as there are scientists, but one that I like is “organized skepticism.” This is one of four norms of the scientific ethos proposed by sociologist Robert K. Merton in 1942. Robert May, the former U.K. government chief scientist, explained organized skepticism as “a journey, over time, toward contingent understanding guided by experimental tests and sceptical questioning.” Skepticism underpins the scientific process, and uncertainty is a pervasive, permanent and evolving feature of scientific understanding.
