Exposure to weakened misinformation builds psychological immunity against it

Evidence

In the same way that vaccines train the immune system to recognize and fight off foreign invaders, often by introducing weakened or dead strains of a virus, it turns out we can inoculate the human mind too. By injecting people with a severely weakened dose of fake news (the virus) and refuting it in advance, over time people can develop mental antibodies – psychological immunity – against misinformation. — Sander van der Linden, Foolproof, 24
