It's in the training/brain washing that all drs go through.

To be safe. Think of all the red flags (ie think of worst case scenarios and never forget what bad things could occur and watch out and be prepared for it)

So drs are essentially trained to be paranoid thinkers.

So staying in institution is safe. going out private where you set your own rules and standards to serve the business model plus have to satisfy the regulations and CPGs is daunting and unnatural to the training as a doctor.
