According to the ModifyNOTA website, fewer than 1% of registered organ donors die in such a way that enables their kidneys to be harvested. Also, a living-donor kidney lasts twice as long on average as a deceased-donor kidney.
Yes it would definitely help to make organ donation opt-out, and we should totally do that, but they're saying this still wouldn't be enough.
your first sentence has nothing to do with what i said because those people already registered. the stat you want is people who are not donors dying in a way that we could've used their organs but didn't.
You think people who would opt-in register for organ donation would be less likely to die in a way compatible with kidney harvesting than others?
I think it's somewhat unlikely that whether or not someone registers to be an organ donor would affect how they are likely to die, but if it did, I would wager that registered organ donors are more likely to die in a way that enables their kidneys to be harvested than others. In any case, I doubt the difference is more than, say, a factor of 2.
