Tobacco Industry Research (1950s–1990s)

For forty years, the tobacco industry knew smoking killed people — and paid scientists to say it didn't.

By the early 1950s, internal research at major tobacco companies had established a clear link between smoking and lung cancer. Rather than acknowledge this, the industry launched a decades-long campaign to manufacture doubt. They funded friendly researchers, published misleading studies, and created organisations with scientific-sounding names whose sole purpose was to muddy the waters. The goal was never to prove smoking was safe. It was to keep the debate alive long enough to protect profits.

The playbook was elegant in its cynicism. You don't need to win the argument — you just need to make people think the science is still unsettled. Internal memos, revealed during litigation in the 1990s, showed executives explicitly discussing strategies to create uncertainty. "Doubt is our product," one memo famously stated. That single sentence explains more about how industries manipulate public understanding than entire textbooks.

This matters far beyond cigarettes. The tobacco strategy became a template. You can see its fingerprints on climate change denial, food industry lobbying, and pharmaceutical marketing. Whenever you hear "the science isn't settled" about something where the science very much is settled, you're hearing an echo of the tobacco playbook.

Funded research isn't automatically bad. But you should always ask: who paid for this, and what did they need the answer to be?
