The tobacco industry's manufactured doubt

That the tobacco industry conspired to suppress its own scientific findings on cancer and nicotine addiction, funded research designed to produce controversy rather than answers, and coordinated a public relations strategy to keep the health question open long after it was scientifically closed.

On 15 December 1953 the presidents of the major American tobacco companies met at the Plaza Hotel in New York with John Hill of the public relations firm Hill & Knowlton. Epidemiological studies linking smoking to lung cancer had begun appearing, and sales were threatened. The strategy that emerged — announced as 'A Frank Statement to Cigarette Smokers' in newspapers the following month — was to promise cooperation with science while funding a body, the Tobacco Industry Research Committee, whose function was to keep the question alive.

Smoking killed an estimated 100 million people in the twentieth century. The industry's playbook — fund contrarian scientists, demand impossible certainty, frame regulation as an assault on personal freedom, work the press rather than the journals — was subsequently adopted almost move for move on leaded petrol, acid rain, asbestos and climate change, in several cases by the same consultants. It is the single most consequential confirmed conspiracy in this archive by body count.
