I think the point is that "doctor bias" will not take a balanced approach to the other systemic factors. I'd argue it's the same with the pilots. If you asked pilots, they'd likely say the same thing: their priorities are going to align with the mission better than anyone else's.

Anecdotally, this has been true in my experience on complex engineering projects. When the project manager is a mechanical engineer, guess which systems get the most time, money, and priority? Mechanical. And when it's an electrical engineer, the electrical system gets the priority. When it's a software engineer, the software etc. They all recognize the other systems, but availability bias skews their worldview and priorities to the neglect of others.
