We All Hallucinate Reality: Turi Munthe on Why We Think What We Think

0 Plays2 hours ago

“If you can only explain the arguments of the other side because they’re mad or dangerous or dumb, the problem is with you.” — Turi Munthe

On yesterday’s show, the psychiatrist Sally Satel described how Americans imagine their own mental condition differently, depending on their politics and age. Which is a nice segue for today’s conversation with the Anglo-French journalist turned media entrepreneur Turi Munthe. It’s not just in our mental health self-evaluation, Munthe argues, that we hallucinate reality. Indeed, the French born Munthe often sounds like one of his post-structuralist compatriots in his defiantly slippery notion of ontological reality.

In Why We Think What We Think: The Unexpected Origins of Our Deepest Beliefs, Munthe argues that our deepest convictions turn out to be shaped by genetics, brain shape and sometimes even by the agricultural legacy of our distant ancestors. Left and right thinkers, Munthe argues, are different political phenotypes — each hallucinating their own version of reality.

Total relativism, then — the full French post-structuralist monty? Not quite. Here’s where Munthe’s Englishness kicks in. Following the Anglo-Russian philosopher Isaiah Berlin, Munthe insists pluralism and relativism are different. So Turi Munthe doesn’t just think what he thinks because of his English or French origins. Borrowing from the cognitive scientists Dan Sperber and Hugo Mercier, Munthe defines thinking as a “contact sport”. So, for example, believing that the 2020 election was stolen is what Munthe calls a social commitment, because humans would rather be wrong together than right alone.

Speaking of convenient segues, Munthe’s thoughts on thinking set the scene for next Tuesday’s conversation with Emily Eakin, author of The Frenchmen. It’s her history of seductive post-structuralists like Foucault, Derrida and Lacan who corrupted a whole generation of literary American Ivy Leaguers (including Eakin) into hallucinating reality.

Five Takeaways

• Pluralism Is Not Relativism. Munthe opens with Isaiah Berlin’s distinction: registering the sincerity and value of opinions across the political, religious, and ethical spectrum does not relativize truth. That Charles Windsor is King of the United Kingdom is a statement of fact; whether you’re a monarchist or a republican is where opinion begins. The book confines itself to the second category — beliefs, values, and opinions that cannot be factually proven — and asks what the nonrational influences on them actually are. The answer is humbling: genetics account for perhaps half of political persuasion, and the rest is shaped by everything from brain anatomy to the agriculture of our ancestors.

• Different Political Phenotypes. At the margins, left and right differ neurologically: right-leaners are on average more readily startled by loud noises and more attentive to threat, while left-leaners carry a slightly larger anterior cingulate cortex — the brain region where we process ambiguity and split hairs. That anatomy, Munthe argues, explains the ideological capture of academia and media better than any conspiracy: hair-splitters go where the hair-splitting is, and a conservative 22-year-old doesn’t volunteer for a newsroom where 80% of colleagues think differently. We are, in his phrase, different political phenotypes, each hallucinating a different version of reality.
