I get half of my political news and analysis from a great podcast called Left Right & Center. (The other half is from Fareed Zakaria’s Global Public Square.) LR&C is an ongoing conversation between three guys from different political perspectives on what’s happened this week, and has been very valuable for the development of my own political thinking.

The other day, I was listening to another great podcast, This Week in Microbiology, and it hit me that these two shows have the exact same format. TWiM is also an ongoing conversation between three guys about the news of the week. The superficial difference is that TWiM is about bacteria and LR&C is about US politics.

The more abstract difference between these two podcasts, though, is that Left, Right & Center is an excercise in outcome-irrelevant learning, while This Week in Microbiology is an exercise in outcome-relevant learning. That is to say, the empirical events of the week change the opinions of the TWiM guys but almost never change the opinions of the LR&C guys. This is a huge difference. On TWiM, when there is a disagreement, they look up what is known about the issue and almost immediately come to an agreement based on facts: either one person is right and the other wrong, or else we really don’t yet know the answer to that question.

On LR&C, when there is disagreement (which there is on every topic), each fact that comes into the conversation is either disputed or used to proove each person’s own point. In politics, the facts are basically irrelevant. Makes me wonder why it remains so interesting.
