The academic pipeline was designed for a person who doesn't exist
I'm a postdoc in physics, and I've been thinking a lot about why the pipeline loses so many people who are good at research. Not because they weren't productive enough, but because the system assumes one kind of person at every stage: someone young, unattached, willing to move anywhere, subsidized by sources the system prefers not to name. Everything else is your problem.
There's a study from 1950 that captures this perfectly. The Air Force measured 4,063 pilots across 10 body dimensions to design the ideal cockpit. The number who were "average" on all ten was zero. The more dimensions you measure, the less likely anyone is to be average on all of them at once. The center is empty.
The academic pipeline works the same way. Publications, h-index, grants: those are the dimensions the cockpit was built for. Whether you have a partner whose career exists, a family, a need for stability? Outside the spec.
The Air Force fixed this in the 1950s by making the seats adjustable. Academia is still building fixed cockpits. I wrote a longer version of this connecting the cockpit study to the two-body problem, supervisor power dynamics, and the "leaky pipeline": https://ergosphere.blog/posts/the-loneliest-point/
Anyone else feel like they're sitting in someone else's cockpit?
