The real question isn't whether debate keeps kids in school. It's whether it finds truth. Your stat is fair, but it proves practice helps, not accuracy. If winning a round meant holding truth, then the best zinger would beat the best evidence, and the audience should bow to whoever performed better. That's absurd. Steelmanning is a useful drill, but the scoreboard still rewards persuasion, speed, and confidence. A quiet expert can lose to a smooth talker and the format calls that decisive. Debate can train reasoning without being a truth-finding tool. Those are different claims.
