Or aren't given a good reason to do it.
I don't really enjoy writing tests at the best of times, for example, because I've never had the enjoyment of inheriting a readable test suite. Most of the time you're looking at coverage hacks that test the runtime and, hopefully, cover some behaviour, and you're lucky if they can give you confidence through a refactoring. Mocks and stubs and spies are helpful tools but I've lost count of the amount of times that the actual purpose of the test is faked without anybody realising it.
But now, this time, there is a purpose and also organisational remit to change this situation and I'm going all in on rebuilding test architecture and writing examples of what we want to see. I'm actually enjoying something I never really enjoyed.
So it is with documentation, or dealing with bugs, or tech debt, or anything like that. It's not really about want or don't want, but why... and if you're on board with the why then it's gonna be better for you than if you're not.
That, of course, depends on solid leadership. So ultimately you're looking at how tight your org ship is.
