Lazar,
While cleaning up my archives, I stumbled upon this episode that might interest you. The episode starts with this claim:
In the battle over smoking efforts to deny a link between smoking and health risks seems to have been completely a lost effort.

I’m not sure how we can reconcile this claim with this other one:
The methods were improved more and more, until people ran out of objections, at which point the conclusion that smoking increased the risk of lung cancer became justified. But it was not wrong of all those people who held out and raised objections for all those years to have done so. It was only because they did so that we can now have confidence that smoking really does increase cancer.
I’m quite confident that there is a way to reconcile these claims. But you have to admit that there are counfounding factors. I blame the lack of cafeine progress.
