Summary

Political outcomes would be relatively simple to predict and understand if only people were well-informed, entirely rational, and perfectly self-interested. Alas, real human beings are messy, emotional, imperfect creatures, so a successful theory of politics has to account for these features. One phenomenon that has grown in recent years is an alignment of cultural differences with political ones, so that polarization becomes more entrenched and even violent. I talk with political scientist Lilliana Mason about how this has come to pass, and how democracy can deal with it.

Hello, everyone. Welcome to the Mindscape Podcast.

to politics and political opinions. I'm not specifically referring now to the actual government,

1:01.9

the new second administration of Donald Trump, and the actions that they and their allies are

taking. That's kind of not what we do here at Mscape, but we want to understand the phenomena.

1:11.5

We want to know what the explanation is for why things are the way they are.

1:16.7
