Ep 2 - What makes a group intelligent or stupid?

In this episode, I explore the strange boundary between collective intelligence and collective stupidity: why groups can sometimes solve problems better than individuals, but also amplify errors, spread misinformation, or coordinate around terrible ideas.

We start from Francis Galton’s classic “Vox Populi” example, where a crowd came surprisingly close to guessing the weight of an ox, and move through Wikipedia, GitHub, fake news, Bellingcat, NASA citizen science, ants, death spirals, diversity, deliberation, remixing, and the possibility of designing better collective systems for democracy and problem-solving.

The main question is simple: what makes the difference between a group becoming smarter together and a group becoming dumber together?
