In my experience, a surprising number of people with a humanities education simply don't believe in "wrongness", but merely differences of opinion. They regard truth as peculiar abstraction used by mathematicians and hard scientists, not a phenomenon that actually exists. It's hard for someone to admit to being wrong if they don't even believe in the concept.
- astazangasta 10y agoYou obviously don't hang out with many statisticians, who also don't tend to believe in truth or being right or wrong; to them, they are just making models that can be tested to reliably approximate some observation. There is no pretense at truth, it's just a model.
- yummyfajitas 10y agoThis is a significant misunderstanding of statistics. Statisticians believe in truth, they just accept that it might not be possible to know it.
- astazangasta 10y agoI think we have a disagreement about epistemology. I say, you can't believe in truth if you don't believe it is knowable. In any case, statisticians are not interested in learning the truth, either, and the goal of their enterprise is not access to it.
- yummyfajitas 10y agoThe entire goal of statistics is to build approximations which converge to truth in some manner or another. E.g., a Bayesian posterior ideally converges to a delta measure on truth as N -> infty. A frequentist point estimate converges to truth (with P = 1) as N -> infty. The entire purpose of statistics is to quantify the difference between our beliefs and actual truth.
- astazangasta 10y ago>A frequentist point estimate converges to truth (with P = 1) as N -> infty. Since we are never at infinity, our observations are always finite, all this is saying is "we always deal with approximations of reality," i.e., statistics is never, in fact, about the "actual truth", it is about testing the set of our limited observations of reality against a model.
- yummyfajitas 10y agoThis is like saying real analysis is not concerned with irrational numbers since they can only be constructed as limits of sequences of rational ones.
- astazangasta 10y agoNo, it's not. The fact that observation is a limit on our apprehension of the real world means the "truth" is fundamentally inaccessible, and is a useless concept to the statistician. All you can hope to do is test your model against the observation, you'll never, ever get access to the truth. As a real-world example that I deal with every day, we frequently model the expected distribution of gene expression as a negative binomial. It doesn't matter how closely we observe the actual distribution of gene expression, it is never going to perfectly fit a negative binomial (it won't even get close), even though this is what we test our observation against, because the 'truth' is something different and far too complex for us to apprehend.
- yummyfajitas 10y agoIrrational numbers are also "fundamentally inaccessible" in the exact same (infinite limit) sense that statistical convergence is. It's not a useless concept at all, it's actually the fundamental concept. What your real world example describes is something different entirely. That's just pragmatically choosing the wrong model due to computational or human tractability. That's not fundamental to statistics, that's just a cheat you made because it's good enough. Statistics is about acknowledging that cheat and quantifying how much it hurts you; fundamentally such a thing is not possible if truth doesn't exist.
- mikebelanger 10y agoI had a philosophy professor who believed evolution was 'just a theory', and routinely dismissed it. I don't think she was religious either. Then again, I had another philosophy teacher who taught logic, which is the most pure use of right/wrong that I can think of.
- PunchTornado 10y agoevolution IS 'just a theory'. like relativity and other scientific theories. it is just a coherent framework to explain observations. today it is our best theory, tomorrow it may not be. you cannot say that evolution is Truth. Truth exists only in mathematics, logics etc.
