What if I told you that smoking two packs a day doesn’t increase your risk of lung cancer? That a highly sedentary lifestyle doesn’t lead to various adverse outcomes? Surely you’d deride me. Conclude I’m off my rocker. Anti-science. A reactionary.
Would it be better if I qualified it to say that these behaviors are not the only causes for these conditions? Maybe, I guess, a little. But when the point is to minimize their importance as main risk factors, the question of motive naturally arises.
