A favorite guest of The Amy Marxkors Show, Dr. F. Perry Wilson of the Yale School of Medicine, joins Amy once again, this time to discuss how social media hacks our brains, leading even logical people down dangerous paths. Dr. Wilson explains the four cognitive biases that can trick our minds and help misinformation proliferate: the illusory truth effect, the framing effect, salience bias, and motivated reasoning. Also, "the summer of the shark" resurfaces, which is reason enough to join the conversation. Lastly, if you're uncertain about showing up for the second vaccine shot appointment, Dr. Wilson has some advice.
