Towards the late days of October, Huffpost's lead pollster started releasing polls claiming greater than 90% probability of a win, explicitly challenging Nate Silver of 538 and his "conservativism" or even manipulating the data. One commenter noted, "we'll know after Nov 8". It was all too funny and surreal, like a guy saying he knows all about carpentry and grasping the hammer head and nailing with the handle.
No, you can't "know" anything from a single outcome, unless you predicted 100% that it wouldn't happen - that your certain hypothesis was refuted. Otherwise, you're simply left with false confidence in 1 data point - unless you bothered to research your outcome.
As background, I'm pretty awful in probabilityand statistics - having the basics of dice permutations down, and getting the math of certain cross-correlations in dependent events, and doing enough damage in trying to model stochastic processes. But mostly I done forgot.
But even if I hadn't, it might not matter. Just as the field of linguistics is going through a phase of rough and tumble re-evaluation after 30-40 years of certainty centered around Chomsky, probability and data analysis is getting an upgrade - perhaps not changing the science, but more how people use it as an art.
In trying to make some sense from this awful year and a half, and draw some usable lessons from it (rather than another set of kneejerk platitudes and I-told-you-soes, I'm digging into both psychology and analytics in the new year to get some different insights - angles I wouldn't have thought of before.
