For computer scientist Chenhao Tan and his team, the internet community called Change My View offered something amazing, a ready-made natural experiment that had been running for years.

All they had to do was feed it into the programs they had designed to understand the back-and-forth between human beings and then analyze the patterns the emerged. When they did that, they discovered two things: what kind of arguments are most likely to change people’s minds, and what kinds of minds are most likely to be changed.

In this episode you’ll hear from the co-founder of Reddit, the moderators of Change My View, and the scientists studying how people argue on the internet as we explore what it takes to change people’s perspective and whether the future of our online lives is thicker filter bubbles or the whittling away of bad ideas.
