Science

Best discussion yet of the is-psychology-a-science question.

And since we're on the topic of science, it's Scientific American's food issue! Some no-brainers (pesticides and fertilizers are not best for soil and not all critiques of GMOs are unreasonable and anti-science); some things you knew, explained (calorie counts on labels are not the whole story because you digest things differently); and some TBD (what's worse, refined carbs or too much food?)
