To hear more, visit rethinkingwellness.substack.comHealth-misinformation researcher and science communicator Timothy Caulfield returns to discuss his new book THE CERTAINTY ILLUSION, why being too certain about anything makes us vulnerable to misinformation, how intellectual humility can help protect us, why science is sometimes “full of shit” and how to be a critical consumer of it, and more. Behind the paywall, we get into why it’s so hard for public figures to show intellectual humility, whether being smart makes people less intellectually humble and more vulnerable to misinformation, the role of narcissism in misinformation belief, the Dunning-Kruger effect, and why so many researchers lie about their work. Plus, Christy asks Tim for advice on how to navigate an alternative-medicine recommendation for IVF, and whether refusing to do it is a hill she wants to die on.Paid subscribers can hear the full interview, and the first half is available to all listeners.
