I think both you and Walter make good points, and both of your comments reflect ways that mine could have been better: notably by creating a false categorical arrow referencing a very I’ll-defined term (“very smart”) and a still imprecise but much better-defined term (“articulate”).
I seem to have recklessly kicked off a red/blue/left/right thing, which was stupid of me.
The much more interesting thing to me is the epistemological failure mode of conflating modern liberal-inflected, coastal-inflected literacy with any other capability, a conceptual error that is well on its way to becoming institutionalized and is perhaps one of a very small handful of fundamental, avoidable mistakes driving a relatively very high level of divisiveness in society.
It’s more than a little meta that the fundamental conceptual error that you’ve highlighted (the siren song of the Central Limit Theorem: everything’s Gaussian until proven guilty) has caused more nation-level financial catastrophes than any other fallacy.
I think there’s ultimately a very compelling case for optimism here that I myself couldn’t have articulated prior to reading your comment in the context of mine: there are known, demonstrable, identifiable, and changeable epistemological practices that are sending shit into a tailspin (and have before), and right in this comment thread there are two of the big ones plain as day: conflating high-status articulation with other forms of merit, and shoving phenomena into convenient but wrong probability distributions.
Those are going to be tough habits to kick, but I see no fundamental reason why they can’t be.
