> Why is a debate worse than a discussion?Debate works really well in two situations:
1. All parties are experienced with debates and enjoy debates. In particular, they can partake in a debate and then, afterward, dispassionately evaluate the arc of the debate; OR
2. The setting is inherently adversarial and there is a third party who will ultimately decide the outcome.
Almost all workplace conversations -- and indeed almost all life conversations -- do not fall into one of these two buckets. In particular:
1. Making use of debate in a search for truth is a difficult and non-universal skill.
For individual debaters to get something out of a debate, they need to know how to disengage from their advocacy and evaluate the arc of the debate from an objective vantage point. This is a skill that requires training. Discussions, on the other hand, allow people to perform this switching between viewpoints as the discussion unfolds. This is much more natural.
2. Adversarial settings create emotional attachment. In debates, people very often become emotionally attached to their arguments and advocacy, causing ego to get in the way of a search for truth. In contrast, discussions do not require a stable advocacy, they are non-adversarial, and no one "wins". These characteristics de-emphasize ego and place the emphasis on whatever actually important issue is at hand.
3. Debates often end up confusing quality of argument with ground truth.
It's always important to remember that constructing arguments is a skill and is time-consuming. It's certainly possible to "win" a debate and still be dead wrong about ground truths -- either by refining debating skill or by throwing more resources into argument construction.
4. Most people don't enjoy debates. I don't have any evidence here, but I think it's probably true. And in a work place, keeping your co-workers happy is probably a lot more important to achieving the company's goals than whatever epsilon benefit debate has over discussion.
Maybe if universities looked more like The Academy everyone would be competent and comfortable in debates, and also understand their inherent limitations as a mechanism in the search for truth. But that's not the world we live in.
So, although I enjoy a good debate as much as the next person, I've found that debates are a truly terrible method for making decisions in most professional settings.
