If I had the option to get annual MRI scans, but I had to sign a waiver that prevents me from suing the doctor or the hospital, then I would gladly take that deal. I'd rather have the data and an expert opinion, instead of no data and no opinion. If they miss something and I die, then no problem (mainly because I'm dead, but also because I would have died anyway). If they do a biopsy and it turns out that it was nothing, then that's also no problem. It's what I signed up for, and I understand that false positives can happen. Hopefully I could find a level-headed doctor (or a black-box machine learning algorithm), and just trust them to make the right call.

The connection between information and stress, and the connection between stress and a wide range of physiological effects effectively proves that more data is NOT always better. It's clear that there are cases where being given more data will reduce the general well-being of the patient.
