Why might our brains be keeping us in the dark about our own motives? What's the reason humans give to charity? How do cultural norms lead to continual efforts to signal to our potential allies?

Robin Hanson is a professor of economics at George Mason University . His latest two books are titled, The Elephant in the Brain: Hidden Motives in Everyday Life, and The Age of Em: Work, Love, and Life when Robots Rule the Earth.

Robin and Greg discuss the discrepancies between what we say and our true intentions.Robin shares how human interaction within our discussions is less about the content and more about social positioning and signaling. Robin talks about the intricate dance of conversations, where showing status, expressing care, and signaling allyship are at the forefront. They also wrestle with the concept of luxury goods and their role in consumer behavior, challenging the conventional wisdom about why we buy what we buy and the messages we're really sending with our choices.

Episode Quotes:

On conscious mind and social norm

23:39: Humans have rules about what you're supposed to do and not supposed to do, especially regarding each other. And we really care a lot about our associates not violating those norms, and we're very eager to find rivals violating them and call them out on that. And that's just a really big thing in our lives. And in fact, it's so big that plausibly your conscious mind, the part of your mind I'm talking to, isn't the entire mind, you have noticed. You've got lots of stuff going on in your head that you're not very conscious of, but your conscious mind is the part of you whose job it is mainly to watch what you're doing and at all moments have a story about why you're doing it and why this thing you're doing, for the reason you're doing it,isn't something violating norms. If you didn't have this conscious mind all the time putting together the story, you'd be much more vulnerable to other people claiming that you're violating norms and accusing you of being a bad person for doing bad things.

Our individual doesn’t care much about norms

20:25: Sometimes norms are functional and helpful, and sometimes they're not. Our individual incentive doesn't care much about that. Our incentive is to not violate the norms and not be caught violating the norms, regardless of whether they're good or bad norms, regardless of what function they serve.

Why do people not want to subsidize luxury items, but they do subsidize education?

46:34: So part of the problem is that we often idealize some things and even make them sacred. And then, in their role as something sacred, we are willing to subsidize them and sacrifice for them. And then it's less about maybe their consequences and more about showing our devotion to the sacred. In some sense, sacred things are the things we are most eager to show our devotion to. And that's why people who want to promote things want us to see them as sacred. So, schools have succeeded in getting many people to see schools as a sacred venture and therefore worthy of extra subsidy. And they're less interested in maybe the calculation of the job consequences of education because they just see education itself as sacred.

On notion of cultural drift

47:55: So human superpower is cultural evolution. This is why we can do things so much better than other animals. The key mechanism of culture is that we copy the behaviors of others. In order to make that work, we have to differentially copy the behavior that's better, not the behavior that's worse. And to do that, we need a way to judge who is more successful so that we will copy the successful. So our estimate of what counts as success—who are the people around us who we will count as successful and worthy of emulation—is a key element of culture. And that's going to drive a lot of our choices, including our values and norms. We're going to have compatible and matching with our concept of who around us is the most admirable, the most worthy of celebration and emulation.
