By 1 January 2067, medical interventions for healthy adults will have been shown to extend average lifespan by at least 25 years

In 2017, Open Philanthropy conducted an investigation on the mechanisms of aging. A section of their writeup considers indefinite life extension, as distinct from modest extension of lifespan, and concludes, with 7% confidence, that by 2067 some collection of medical interventions for adults will have been shown to extend adult lifespan by at least 25 years.

This question will resolve according to Open Philanthropy's explicit criteria:*

By January 1, 2067, there will be [some] collection of medical interventions for adults that are healthy apart from normal aging, which, according to conventional wisdom in the medical community, have been shown to increase the average lifespan of such adults by at least 25 years (compared with not taking the interventions).

The prediction is called off if some other innovations cause a historically exceptional increase in the rate of scientific progress during this period (such as the development of transformative AI capabilities). The prediction excludes diet, exercise, and lifestyle, as well as existing medical interventions for healthy people (such as currently available vaccines).

Metaculus administrators will judge whether the criteria have been satisfied.


*The wording in the original Open Philanthropy report has been slightly altered so that a positive resolution corresponds to the occurrence of the relevant medical breakthrough (rather than to its failure to occur).


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.

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.

Community Stats

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.
