>That's a really scary line of logic though. "We did a thing, and there was no effect. We propose that to obtain the desired effect we should do even more of the thing that had no effect."

Is it scary? I mean, if I go from getting no exercise to spending 30 seconds a day exercising, but see no change in my weight, should I therefore conclude that exercising is pointless? Or should I try exercising more and also maybe be more careful with my eating habits?

I think the scary thing is when people try to take complicated subjects and distill them down to shallow talking points.
