<p class="MsoNormal">Similarly, a modern poker pro isn't trying to guess what the opponent has. The modern player is trying to put the opponent on a spread of possible hands under the circumstances. The outcome of any given hand doesn't matter, and there is
an expected amount of variance in performance even under a game-theoretic perfect strategy. The question is whether the strategy pays out in the long run, and whether the player has a deep enough bankroll (in comparison to the stakes they are playing at) to
ride out the variance. If you think the pro is doing something else, you probably are still a very long way from getting to that level. <o:p></o:p></p>

-------- Nick says --------- Nate constantly says that making such predictions is, strictly speaking, not his job. As long as what happens falls within the error of his prediction, he feels justified in having made it. He will say things like, "actually
we were right." I would prefer him to say, "Actually we were wrong, <i>but I would make the same prediction under the same circumstances the next time.\u201d </i>In other words, the right procedure produced, on this occasion, a wrong result. -----------------<o:p></o:p></p>

Well... so this connects a lot with poker, which I am in the process of teaching the 10 year old... If I recall, Nate was giving Trump a 1/3 chance of victory, which was much higher than most of the other models at the time. You can hardly fault someone because
something happened that they said would happen 2/3 of the time. <o:p></o:p></p>

If a poker player has a model that predicts a given play to be the best option, because it will work 2/3 of the time, and this one time it doesn't work, that isn't grounds to say the model failed. <o:p></o:p></p>

YOU want the modelers to have models that rarely give anything close to even odds. So do I, so I'm sympathetic. But the modeler might prefer a more honest model, that includes more uncertainty, for a wide variety of reasons. <o:p></o:p></p>

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">I think it's interesting that you seemed to have *flipped* your thinking within the same post. You restate my point about conceptual metaphors by saying models/computation merely
*justifies* decisions/rhetoric. Then a few paragraphs later, you suggest that's conflating language with thought.<br>
<br>
My diatribe to Nick was that he *uses* metaphors/models simply to impute his conceptual structure onto Nate. Nick's decision is already made and he wants Nate's work to justify it. And the way he *imputes* his conceptual structure into Nate's work is through
the sloppy use of metaphor. Then when Nate tells Nick (indirectly) that Nick's wrong about what Nate's done, Nick rejects Nate's objection.<br>
<br>
I'm picking on Nick, of course. We all do it. I wish we all did it much less.<br>
