The physician concludes that magnetic fields likely help alleviate some back pain. She bases this on a study where the group of patients who had magnets placed on their backs reported greater pain reduction than those that didn’t.

Given that one group didn’t receive any treatment at all, the author must believe that the mere act of receiving treatment doesn’t cause pain relief. She therefore assumes that the magnets aren’t a placebo. She also assumes that the relief patients receive from the magnets isn’t offset by a spike in pain once the effects of the magnets wear off.

The magnets are a placebo. Had the other group had virtually anything vaguely “medicinal” applied to their backs, they too would’ve seen an improvement in their condition. Thus, the physician’s conclusion doesn’t follow.

We don’t care about magnets compared to more effective medications. We only care about whether magnets are themselves effective in alleviating back pain.

We only care about back pain. That’s all the physician concludes about.

Irrelevant. If those scientists weren’t involved in conducting the experiment, then they couldn’t have compromised the study.

We don’t care what caused the pain in the first place. We care how well, if at all, the magnets relieved it.
