Why winning arguments backfires (with Tamsen Webster)

What if the very moment you decide to win an argument is the moment you guarantee you will lose it? Socrates understood this. His commitment to genuine dialogue, to speaking truth openly and inviting others to do the same, was a practice the ancient Greeks called parrhesia. It eventually cost him his life. It has quietly disappeared from the way most of us communicate today. What replaced it was debate. And debate, as persuasion researcher Tamsen Webster explains in this episode, is a form of discourse rooted in the idea of beating and defeating. It is a tool designed for winning. In this episode of Inner Propaganda, I sit down with Tamsen Webster, design expert, persuasion researcher, and doctoral candidate, for one of the deepest and most wide-ranging conversations I have had on this show. Tamsen has spent more than 25 years studying what it actually takes to change minds ethically and durably, and she is now channeling that work into a doctoral dissertation on the novel ideas required to make genuine aha moments possible.

Ask yourself: What are they saying as if it were fact? What must be true for that to make sense to them? What would I need to understand or have experienced to reach the same conclusion? Write it down. You are not trying to agree with them. Just trying to see clearly.
