| > That was a very sophisticated formulation of "I don't listen to people whose politics I disagree with." It wasn't. It was an argument for believing that "in many cases it matters where the arguments that I hear come from." Let me be clear: I don't like the fact that I think this policy is right. I just think it's right. And let me also be clear that in many or most cases it makes sense to disregard the source of an argument. In most exchanges on HN, the people involved all implicitly agree on the data that's being argued from, and in those cases I tend to think that we don't ever need to think about people's biases. But the fundamental belief underlying the "we can always disregard an argument's source" movement is that sufficiently logical and dispassionate people can validate or invalidate an argument very easily (compared to the work it took to formulate the argument in the first place). I really really would like this to be true. I just don't think it is, IN GENERAL. To reiterate why: I think it's perfectly possible to follow a logical train of thought without actually re-deriving that train of thought -- and so I think that we can untangle argument and arguer when arguments are purely logical -- but if an argument is based on data from a complex system I don't think it's possible to determine if that data was chosen in an unbiased manner without actually looking at all the available data and essentially re-deriving the arguer's conclusion. Combine that with two hopefully-obvious (and hopefully-true) premises: first, that a large data set on any sufficiently complex system contains individual data points that support any given belief about that system, and second, that most really complex systems can't be considered completely logically, because there's so much going on, and must instead be approached by looking at data, and I think it follows that you need to think about the source of any argument about a complex system when you're deciding whether you (provisionally) believe it. Incidentally, I find it genuinely ironic that your post is actually a not-particularly-sophisticated example of "I don't listen to people whose politics I disagree with," since you ignored my argument based on my dissenting conclusion. |
But this is exactly what I come to Hacker News for. In this case, there are definitely HN readers who can understand the code ESR is talking about, and pretty quickly figure out if there are flaws in ESR's reasoning regarding the code in question.
Once we have the actual flaws in his reasoning, his tea-baggery or whatever become completely irrelevant, because we have much more solid reasons for rejecting his conclusions. If this were a different forum, with no participants well versed in technology, mathematics, and the scientific method, maybe you need to consider the motivation of the arguer when considering the validity of the argument. HN is not that forum.
