Teaching gimmick - Tradução em português

Pulling bad science apart is the best teaching gimmick I know for explaining good science.
(A tradução de "gimmick" que eu conheço é troço, coisa, mas para esse título ela não se encaixa.)

Alternative therapists don't kill many people, but they do make a great teaching tool for the basics of evidence-based medicine, because their efforts to distort science are so extreme. When they pervert the activities of people who should know better – medicines regulators, or universities – it throws sharp relief onto the role of science and evidence in culture. Characters from this community who wonder why people keep writing about them should look at their libel cases and their awesomely bad behaviour under fire. You are a comedy factory. Don't go changing.
