      Nice summary. OTOH, underlying problem is that the shape of good scientific work (high risk, long-term orientation) doesn’t fit the shape of individual careers in any currently plausible institutional framework. No full near-term solution is possible. https://twitter.com/jayvanbavel/status/998307085791064064 …

      Sufficiently large institutions should have no problem with a portfolio of such "investments" as long as they can distinguish legitimate high risk / high reward work from work that is simply doomed to fail from the beginning.

      The latter is the problem. Accountable institutions have to evaluate people “objectively” instead of on the basis of “JSB thinks she’s a smart weirdo”. It’s the attempt at objective fairness that creates a Goodhart’s Law dynamic, which is why 95% of science is wasted effort.

          Yes. Very fine article, and the university system (including academic science) seems near the cusp of collapse on multiple fronts.

          "Brilliant scientist recognizes another brilliant scientist" probably has higher true positive performance than any other metric, but a) it doesn't scale at all b) it's incredibly punitive to people who are not in the 'right' social networks

          It can also go horribly wrong if the people that end up in the selection committees turn it into a system of patronage for their own protege (see a huge percentage of Italian academia, with the so called 'Baroni': https://www.ilfattoquotidiano.it/2017/09/25/universita-concorsi-truccati-se-fai-ricorso-ti-giochi-la-carriera-la-logica-di-scambio-dei-professori-indagati/3876949/ …).

          "Objectivity" only works if the model generating the metrics is *objectively* correct. In these domains, it rarely is. More specifically, I argued that ignoring trust and replacing intuition with metrics is a key failure point:https://www.ribbonfarm.com/2016/06/09/goodharts-law-and-why-measurement-is-hard/ …

          Interesting side effect of trying to be objectively fair. Goodhart’s law basically seems impossible to beat
