Conversations with Tyler: Jared Diamond on Why Leaders Matter Less Than You Think

**SPEAKER_1** (0:01)
Welcome back, everyone. Today we're diving into Tyler Cowen's fascinating conversation with Jared Diamond about his new book, Prophets, Coaches, and Kings. The big question Diamond tackles is: when do leaders actually matter, and when does history just roll on without them? And his answer is surprisingly unsentimental, right? He basically argues that no leader is truly irreplaceable because over a long enough timeline, events tend to wash out. That's a bold claim. It really is. He even applies this to figures like Jesus Christ and Muhammad. Instead of calling them uniquely transformative, he points to the wider forces and supporting figures around them. Then he contrasts that with Genghis Khan, whose rise was actually helped by unusually wet weather that made his massive armies possible.
So the point isn't that leaders are irrelevant, but that context determines how much room they have to make a difference.
That's interesting, because some people might think this contradicts his earlier work on geography and civilizations. Diamond addresses that directly. He says he's simply asking different questions on different time scales. His books like Guns, Germs, and Steel focus on why societies rose through plants, animals, and location over millennia.
This new book examines shorter-term outcomes, like the distinct effect Jeff Bezos had on Amazon.
And he does name specific leaders as significant. He calls Hitler the most destructive leader of the twentieth century, while praising Rachel Carson for jump-starting the environmental movement and John Wooden for his psychological and tactical brilliance at UCLA.
What really struck me was his discussion of communication skills. Diamond argues that ambitious young people today underestimate the importance of face-to-face communication. He mentions that in New Guinea, people become highly skilled at direct negotiation because they have no telephones. Meanwhile, Western societies have seen a decline in writing, speaking, and interpersonal ability as life moves online. He extends this to business leaders like Steve Jobs, Elon Musk, Bezos, and Zuckerberg, saying they mattered because they worked in areas where a decisive person could still make a tangible difference. Diamond also reflects on big historical patterns and praises economists like Daron Acemoglu and Jim Robinson for studying institutions through natural experiments. But what's his outlook on our future? He's cautiously hopeful, actually. He says there's a 51% chance of a good outcome on climate and nuclear risk if people keep communicating directly and seriously. And personally, he's working on synthesizing decades of research on New Guinea birds, getting through all 200 Bach cantatas, and most importantly, contributing to his family's happiness. A thoughtful combination of global concerns and personal priorities. That's Jared Diamond for you.
