Both sides are wrong. Resusitation is more likely for a donar (if there is any bias).
OK, maybe a panel of neurologists looking at an ECG are going to be biased if you are stable but not reviving. But it's a panel of neurologists looking at an ECG. Mistakes are rare.
Before getting to the ICU, you've got the paramedics, triage nurse, and ED team, all of whom are also hypothetically going to be biased just as much to get you stabilised if you're a potential donar. Is the paramedic going to run a red light? Will the ED doctor work an hour past their shift when they can just read out the time and go home?
The info isn't on your license to tell the panel of neurologists. It's there so that the paramedics know to switch on the lights even if they think it might be a hopeless case.
