Common wisdom is that even if you can’t convince your opponent, you are arguing for the benefit of the audience. I have come to believe this is much less favorable is usually imagined.
For a couple of months, I’ve been at debate.org. I’ve had 7 debates. The debates are judged by whoever. This is a good example of a time when you probably can’t convince your opponent, but your goal is to appeal to an audience. The end result is revealed when people in the audience vote, so it gives an insight into what goes on in people’s heads when they observe arguments.
So what are the results? Here is what happens. You can beat your opponent. I mean really clobber them to within an inch of life. You can hit back every one of their arguments with 3 strong counter arguments. They can fail to address 95% of your case and be completely off topic. Don’t think I’m exaggerating. It happens all the time.
And then, people don’t vote for you. They side with the other guy. Why? Because while listening, they thought up with an argument that you didn’t address. You can address all your opponent’s arguments, but you’re not psychic, so you can’t address the arguments the audience makes up. For example:
A: The war in iraq is stupid because it kills lots of people
B: But it stabilizes the middle east for democracy
A: No it doesn’t. There is political chaos now forever and ever. Also, it kills people.
Audience: “But Saddam was bad” “What about the oil?” “What about Israel?” “What about 9-11?” “What about my uncle who’s over there?”
Those are all dumb things for the audience to think. You could rebutt them in 10 seconds, but you can’t because you’re not arguing with them and you’re not psychic. The end result is that the audience thinks what it thought before.
I mean really - how many debates have you seen between free markets and socialism? Both sides have probably won flawless victories against each other. Does it convince anyone? No. Because the times when free marketers lose I’m thinking “damn the free market guy didn’t say X”. But maybe the socialist could have rebutted it!
So the audience can always run away from the truth. They can hide behind hypothetical arguments that never ocurred in the argument. You have to draw people out into a 1 on 1 debate so that THEY can see that THEIR arguments don’t work.
Sorry to be so pessimistic, but I have to be honest about the limits of discourse. People are outrageous and incorrigible. The human race has cognitive dissonance. It must be engaged directly.
