I have a large stash of nonsense I could write that might be on topic. But the topic coincides with an argument I had about 2 weeks ago. My opponent said something generalizing about the use of statistics and I made a comment (I thought was funny, but apparently not) that I don't really know what statistics _is_. I also made the mistake of claiming that I _do_ know what probability theory is. [sigh] Fast forward through lots of nonsense to the gist:
My opponent claims that time (the experience of, the passage of, etc.) is required by probability theory. He seemed to hinge his entire argument on the vernacular concept of an "event". My argument was that, akin to the idea that we discover (rather than invent) math theorems, probability theory was all about counting -- or measurement. So, it's all already there, including things like power sets. There's no need for time to pass in order to measure the size of any given subset of the possibility space. In any case, I'm a bit of a jerk, obviously. So, I just assumed I was right and didn't look anything up. But after this conversation here, I decided to spend lunch doing so. And ran across the idea that probability is the forward map (given the generator, what phenomena will emerge?) and statistics is the inverse map (given the phenomena you see, what's the generator?). And although neither of these really require time, per se, there is a definite role for [ir]reversibility or at least asymmetry. So, does anyone here have an opinion on the ontological status of one or both probability and/or statistics? Am I demonstrating my ignorance by suggesting the "events" we study in probability are not (identical to) the events we experience in space & time?
