For me, doing a postdoc would mean relocating regularly, my wife having to find new jobs with me (a big stress point for her), a huge amount of job insecurity, etc.

By not doing a postdoc, I’ve been able to find a permanent job that pays significantly more, buy a house, and actually start to think about starting a family, which is more important to me.

I think if you’re single and male then it’s OK but it’s not surprising for e.g. that there are underrepresented groups in some fields of science at lectureship level when they basically have to sacrifice any stability in order to get to that position. I grew up quite poor and do not want to get into that position again - and I can’t afford to not have a job gap for 4 months which is the sort of length I’ve seen friends endure while one contract ends and another starts.
