A very close relative of mine passed away 2 weeks ago. She had cancer for 2 years and when she was first diagnosed the doctors would give her 8-10 “good years”. Well... When she died, I was shocked to learn that very few data points of her sichkness and treatment history would be preserved for later analysis. Doctors work almost entirely on their gut feeling and probably some clinical studies with n being very small.…
I'm a GP, and I see dozens of patients every year with cases of Foozle disease. I was taught in medical school to give them orange pills, but I follow developments in general medicine and I know the new purple pill has seen good results for Foozle too. Nobody has published even a small study about which is better.
The law says since a responsible doctor wouldn't know one is better I can choose either. I could give all my female Foozle patients the orange pills and prescribe the purple for everybody else, or I could just pick whichever is cheapest, or I could even pick randomly for each patient. All legal.
But, if I pick randomly AND record the results, thus doing science to find out which was best, that's an unauthorised medical experiment and I could lose my job or even go to jail.
