It’s a favourite behavioural science story. Countries that have opt-in organ donation have lower rates of organ donation than countries where you have to opt out of being an organ donor. If we change the way the choice is framed from opt in to opt out, we can dramatically increase the rate of organ donation.
Except, it’s not that simple. For countries where there is an opt-out system, there is no simple point where the choice is presented to them as the default and they can easily tick the box to be removed from the organ donation register. Instead, they need to find and fill out forms or call various government agencies to overcome a presumed consent.
Further, although opt-out countries tend to have higher donation rates, some countries with opt-in systems have higher donation rates than those with opt-out. The high numbers that get reported – 99.98% of Austrians are organ donors – are the numbers who haven’t opted out, not the number who donate. When it comes to the point of donation, other issues become more relevant, including the wishes of the family. It’s no surprise that the family might wish to intervene, particularly given that in an opt-out system there is no moment where the donor is required to express their wish.
It seems to have been on the cards for a while now, but I’ve just realised Wales is shifting to being an opt-out country. The rolling out of this nudge is lazy.
Instead of trying to design a system where they actually determine the wishes of the person and their family, they rely on the inconvenience of having to opt out to boost registered numbers. At the time of death, the family will have no sense of what the deceased wished for- after all, the number of people who choose to opt out is far less than the number who than indicate in surveys that they do not wish to donate.
There is no shortage of alternative approaches that don’t rely on granting (or attempting to grant) the right to organs through omission. Active choice is one option – when people get a driver’s licence or tax file number, ask them to choose whether they wish to be an organ donor or not. It will likely increase the number of registered organ donors over an opt-in system, while proving some indication of people’s wishes. An active choice also indicates these wishes to the family, with those wishes one of the major factors in families agreeing to donation.
Then there are the more interesting options that could be tested – markets for organs, preferential treatment for those on registers (as occurs in Israel), or systems to match donors. These options are often prohibited.
Instead of increasing the freedom to develop new solutions, we have a misunderstood story about a nudge gaining momentum, inadvertently placing the burden on family members at the time of death.
As an aside, I’m still hunting for examples of nudges introduced explicitly to increase freedom by allowing a hard requirement to be relaxed. Current count remains at zero.
