Harvard psychologist and bestselling author Steven Pinker is a fierce advocate for intellectual and academic freedom — and one of the world’s most prominent and provocative thinkers about human language, the mind, and how societies work. He joins Big Ideas host Natasha Mitchell with an 800-strong Melbourne audience to discuss his latest book When Everyone Knows That Everyone Knows: Common Knowledge and the Science of Harmony, Hypocrisy and Outrage. Steven Pinker doesn’t shy away from controversy — amidst the Trump administration's attacks on his own university he recently penned a NYT piece titled Harvard Derangement Syndrome — challenging the cancellation, character assassination and censorship of scholars who investigate controversial ideas.
