Coming from another field, 23 years as a post-doc seems insane to me. Is this common in some fields? I never thought of post-docs as (semi-) permanent positions or something one would spend a major chunk of a career doing. I always thought of it as a transitional position, something people did while they worked on getting their own funding or transition to industry. Am I wrong or are there different standards in diff…
Obviously not everyone can promote all the way up, and not everyone wants to. There’s nothing wrong with someone doing good competent work at the level of a postdoc for as long as they want. We have a postdoc in his 40s in the lab I used to be in and he does excellent work as part of a group. I don’t think he wants to run his own lab and why must he?
1) As postdocs get more experienced, their pay usually goes up.
2) As mentioned in the article, it's possible to "age out" of a lot of fellowships, which have limits like "5 years since your last degree" requirements.
Which means the burden then falls on the PI of the lab to support them as essentially a staff scientist.
If I pay a postdoc $60,000 a year, at 10% pay lines (which is not unreasonable for the NIH), I have to write about $600,000 in grants in expectation to be able to afford them. That's a lot of work, and unless they are significantly better than a new postdoc, potentially not worth it. They're also not a good speculative investment - they're not going to go on to be a PI of their own lab, which has benefits for their PI down the line.
