First human head transplant by end of 2020?
Transplantation of tissue — including organs — from one human (or nonhuman) to another is an amazing advance in medicine that has now saved many lives. Complex organs including the heart and liver are now routinely transplanted, and in many cases even quite complex severed nerves can be reattached.
Much more audacious is the possibility of transplanting a human head. (Or should it be considered a full-body transplant?) The difficulties are obviously daunting: not just the spine, but major arteries, throat, etc., must all be reattached while keeping the brain alive.
Recently, the media has been abuzz with news that Sergio Canavero and his colleague Xiaoping Ren of China plan to transplant a human head from a living person onto a donor cadaver. The two surgeons — who portray themselves as pioneers defying a stodgy medical establishment but are considered reckless renegades by many peers — say the head donor will be someone with a degenerative disease, whose body is wasting away while his or her mind remains active.
The body donor, meanwhile, will likely be a someone who died of severe head trauma but whose body was left unscathed. The researchers claim to have been perfecting the technique on mice, a dog, a monkey, and, recently, a human cadaver. Originally, they predicted a fall 2017 transplant but now just say it is “imminent.”.
This same question was asked for 2017, which most then correctly predicted to be unlikely.
By the end of 2020, will a human head transplant operation be performed?
Resolution is positive regardless of the survival of the patient after the operation. Positive resolution requires the patient who provides the donor head to be alive right before the procedure: the patient providing the donor head should not be declared legally dead 48 hours or more before the transplant occurs.
Metaculus help: Predicting
Predictions are the heart of Metaculus. Predicting is how you contribute to the wisdom of the crowd, and how you earn points and build up your personal Metaculus track record.
The basics of predicting are very simple: move the slider to best match the likelihood of the outcome, and click predict. You can predict as often as you want, and you're encouraged to change your mind when new information becomes available. With tachyons you'll even be able to go back in time and backdate your prediction to maximize your points.
The displayed score is split into current points and total points. Current points show how much your prediction is worth now, whereas total points show the combined worth of all of your predictions over the lifetime of the question. The scoring details are available on the FAQ.
Note: this question resolved before its original close time. All of your predictions came after the resolution, so you did not gain (or lose) any points for it.
Note: this question resolved before its original close time. You earned points up until the question resolution, but not afterwards.

Metaculus help: Community Stats
Use the community stats to get a better sense of the community consensus (or lack thereof) for this question. Sometimes people have wildly different ideas about the likely outcomes, and sometimes people are in close agreement. There are even times when the community seems very certain of uncertainty, like when everyone agrees that event is only 50% likely to happen.
When you make a prediction, check the community stats to see where you land. If your prediction is an outlier, might there be something you're overlooking that others have seen? Or do you have special insight that others are lacking? Either way, it might be a good idea to join the discussion in the comments.
