Scene: a coffee shop where two people are in a heated discussion over a complex topic.
Galina: “So you can see that, generally speaking, this is predominantly the case!”
Bob: “No! What about this one time, that thing happened! That shows that you’re completely wrong!”
Galina, confused: “I don’t understand what that has to do with this?”
Bob: “Hey, this isn’t my area of expertise. I’m just being a Devil’s Advocate….”
This scene is all too common, and it’s immensely frustrating for people who have spent time and energy learning about a topic to be “refuted” by someone who knows very little. “Refuted”, though, is not the same as refuted, because Bob hasn’t actually offered a useful counterargument. No, Bob is just being a contrarian jerk. And contrarian jerks love to claim that they’re “just being a Devil’s Advocate”.
