      So much relevant expertise in political science. This would be so much better as a team project that included them.https://twitter.com/GovernorTomWolf/status/962060492175900674 …

      I have enlisted an esteemed mathematician, who has done extensive work on determining fairness in mapmaking, to provide non-partisan analysis of maps to determine their fairness.

      Realize my point is not that a mathematician should not be involved. It is that such a politically complex problem requires far more diversity of expertise & polisci expertise is essential (see work of Scott Page on this pt: https://aeon.co/ideas/why-hiring-the-best-people-produces-the-least-creative-results …)

      This is a fun article, and there's interesting truth to it. But I wish it engaged seriously with the other viewpoint. Is there ever a good time to turn down a von Neumann for your math-focused venture? Einstein for a physics venture? Etc.

      If the answer is just "You get experts whose domain expertise is more appropriate [than Einstein etc] for the particular problem under consideration" then the article becomes true but obvious and uninteresting.

      The likelihood that you will get someone who understands the math _and_ the institutional politics _and_ the local specificities of Pennsylvania politics is obviously very low. Genius travels - but nearly always within a specific ambit and with a specific bag of tricks.

      So I think you need to integrate very different kinds of expertise if you want to answer these questions. Though I can’t remember how/if you talk about these specific kinds of cognitive crossover in Reinventing Science …

      I gave a few very examples - there are some particularly nice ones in Kasparov versus the World where amateurs contributed important ideas that the experts didn't think of.

      Yes, I like that example a lot. I do disagree with the sharp division you draw between science and politics in that book (science seems more political to me, and politics at least a little more concerned with search for knowledge than you say, as best as I recall it).

      I was trying to make a very specific point about the conditions under which knowledge can build. I'd be a bit more measured today, particularly understanding some of the problems around replication - many fields of science seem to barely deserve the term.

      By contrast, there are parts of mathematic & physics (& a few other fields, though spottier) where it's possible to make tight arguments thousands of pages long, integrating the results of tens of thousands of people. I know of nothing remotely like that in politics.

          The complexity of the argument behind something like the Poincare conjecture (which I do _not_ understand in detail, though I understand pieces of the background) is really astounding, and relies on very, very tight conditions for accepting results.

          Conversely (and this is a point that Sperber makes in his fantastic book Explaining Culture) to properly understand a mathematical proof is to _know_ that it is right, which is profoundly different from more social forms of knowledge. But I’ve hijacked Corrine’s feed for too long

          The Unfeasibly Large Proof or whatever it is (it always sounded to me like something out of one of the more delightfully improbable Douglas Adams novels).
