But that is a value judgement, and I believe it is one that comes at a great cost to society- I wouldn't be surprised if >50% of the cost of medical care is directly or indirectly due to this attitude, and that medical progress has been slowed immensely for the same reason.
If we could make medical data more open, it would greatly benefit the vast majority of people. OF COURSE it is true that some smaller number of other people/patients are helped by the existing medical secrecy system. I fully admit this is a trade-off, where we have to decide what values are more important.
