reflecting on @KevinSimler’s interactive essay. It’s fun and easy—read it first!
His post has a sudden plot twist toward the end, and takes on a darker tone.

Kevin’s post interactively illustrates and applies percolation theory. I’m envious and admiring; I’ve been looking for an application of percolation theory for 30 years. He found one right where I’m working now, in understanding scientific progress! https://meaningness.com/metablog/how-to-think …pic.twitter.com/R9WH16yfcU

The last in Kevin’s series of interactive illustrations shows the effect adding a fraction of “careerists” to scientific knowledge networks. Once you get to a critical percent, they shut down progress. The model isn’t quantitative, but usefully conveys the intuition.pic.twitter.com/WWTtIcZCro

Careerism is a natural consequence of the incentives created by what Richard Feynman called “cargo cult science.” https://meaningness.com/metablog/upgrade-your-cargo-cult …pic.twitter.com/3KdDtC2pk7

“Careerism” has the implicit implication that science is a GOOD career, and people do it for that reason. Unfortunately, it’s a terrible career, and one reason we have so much bad science is that many of the people who could best do it choose not to, because they figure that out

Conversely, most people currently working in science shouldn’t be. They either can’t do it, or don’t really care to. (Maybe they could or would given better incentives.) As Kevin observes, going-through-the-motions science has crowded out the real thing. https://meaningness.com/metablog/upgrade-your-cargo-cult …pic.twitter.com/mQ5P1cSFQB

Making science a not-terrible career has to be part of fixing incentives. But then more people will be attracted who want good careers. So there has to be a filter. Which is what brought us to the current impasse:

Most of what scientists do is artificial activities required to get yourself through endless steps of career filtering, put in place with good intentions to ensure that only good science is funded, but which instead almost completely replaced actual science.

Replying to @Meaningness
Curious if you have a take on how this applies to academic pure math. My sense, from my stint in grad school, is not that nobody's doing "actual math" but that the entire apparatus has gotten totally disconnected from the rest of the world.

That sounds right to me; but I didn’t go far enough with math to have an informed opinion.
