Truth Labs for Education is a collaboration between Cambridge University, the University of Bristol, and Google Jigsaw. We created a series of short videos designed to help people resist unwanted persuasion online. The videos are rooted in a framework from social psychology called inoculation theory, which posits that by exposing people to a weakened dose of a persuasive argument or technique and pre-emptively refuting it, they develop psychological resistance against future manipulative persuasion attempts.
We created 5 videos, each of which “inoculates” people against a particular manipulation technique or misleading rhetorical device commonly encountered online: ad hominem attacks, using emotional language to evoke fear or outrage, false dichotomies, incoherence, and scapegoating.
