I think this is equally true of writing. Once you see something written one way, it's very hard to imagine other ways of writing the same thing. The influence of anchoring bias is quite strong.

A strong editor is able to overcome this anchoring bias, imagine alternative approaches to the same problem, and evaluate them against each other. This is not easy and requires experience and practice. I am starting to think that a lot of people who "co-write" with ChatGPT are seriously overestimating their own editing skills.
