Good points. I didn't see it as tu quoque, though; I saw it as an opportunity for Eliezer to qualify his heuristic and bring it more in line with reality.

It seems to me that "logical etiquette" requires us to respond to the very strongest arguments made by our opponents as well as to read arguments reasonably. Without going back to this discussion, it's hard to tell who is being rude.

For example, suppose I make the following argument:

"American law schools always charge ridiculously high tuition because they can get away with it. The availability of generous student loans creates artificial demand and gives law schools the ability to charge exorbitant tuition. We need to reform the student loan program to fix this problem."

If somebody responds by simply saying "well, I know a law school in Nebraska which charges $500 per year so your premise is wrong," they are being rude. Because obviously when I said "always," I really meant "generally speaking." Further, the person is not really responding to the substance of my argument.

I have no idea if this is what happened with Eliezer and Thomas. I'm just saying.

I went and looked at the original post - it's very long, but does actually address Thomas' question:

Or imagine that the combination [to the lock that we're trying to pick] changes every second. In this case, 0-0-0-0, 0-0-0-0 is just as good as the randomized algorithm - no better and no worse. What this shows you is that the supposedly "random" algorithm is "better" [than trying 0-0-0-0 repeatedly] relative to a known regularity of the lock - that the combination is constant on each try. Or to be precise, the reason the random algorithm does predictably better than the stupid one is that the stupid algorithm is "stupid" relative to a known regularity of the lock.

Given the length of the post, I think the most reasonable assumption is that Thomas had forgotten that that particular point had been covered by the time he reached the end of it. I know I had by the time I saw his original question.

That's really pretty ridiculous. You can try to speak precisely. Why should we all concede that hyperbole is acceptable in an argument?

If you want to argue about student loans you could: approach it from another side or focus on elite/private law schools. Overstating your case only works when preaching to the choir. Then, it misinforms and makes you less credible to others.

This seems like the perfect place for the person making the claim about student loans to make a concession (demoting their "always" to "almost always") thus making their debating partner more comfortable to listen to the meat of their argument; but it is also necessary not to take that demotion from "always" to "almost always" as defeat of the entire argument.

I basically agree, and in this situation my response would be something like "I concede that not all law schools charge ridiculously high tuition but I think my basic point stands.

Sometimes that sort of precision adds too much length. If you see an easily-fixed problem with an argument, it behooves you to point out the fix in the same comment as the problem.

I think that is fair. That would be the reasonable thing to do in a debate.

Precision in this case is not any longer (i.e. always vs typically). It can at times, but for people down with logic, you'd think always versus there exists, etc. would be a big deal.

Comment author: ciphergoth 29 January 2010 07:15:34PM 0 points [-]

Actually in this instance it's made more precise just by leaving out the word "always".

Hmm, you don't think omitting it also implies all schools do it?

Comment author: ciphergoth 30 January 2010 12:21:50AM 2 points [-]

No, compare "cats have fur" vs "cats always have fur".

Why should we all concede that hyperbole is acceptable in an argument?

I'm not saying that hyperbole is acceptable. But if I engage in hyperbole, it's still rude to nitpick the hyperbole while ignoring the strongest part of the argument. In this case, the argument still stands if one substitutes "generally speaking" for "always."

You can try to speak precisely

Sure, but it's difficult to be sufficiently precise at all times. It's rude to seize upon an inprecision to dismiss an argument while ignoring the main thrust of the argument.

I'm trying to make the point that its easy to jump on (especially glaring) imprecision. Your general thrust is weakened, often unfairly, by its presence. It can be a bummer for an argument if people jump on imprecise things, but hopefully you can stop that before it happens by omitting them in the first place.

I agree. But at a certain point, you have to rely on the other fellow to be reasonable in interpreting what you say.

To illustrate, it takes a lot of time and effort to formulate something like this:

The sky of the planet Earth is usually blue when viewed during the daytime from the surface of the planet.

It's a lot easier to simply say "the sky is blue." Any reasonable person understands what you mean.
