Why wouldn't I experience placebo effects if I started drinking as the result of controlled trials which suggest that drinking will reduce all-cause mortality?
I want to know the effectiveness of the combination of chemical effects and placebo effects from the treatment I take, not the effectiveness of an outwardly similar treatment that has had significant changes made for the purpose of getting results different from the results I should expect.
