I understand that Metaculites may experience some unease over this question, since it seems very unlikely to resolve positively, even given my generous resolution criterion. However, I think it's an important question in order to keep journalists and public health policy analysts in check. These types of questions demonstrate how informed communities of amateur predictors can often outperform the experts.

I formulated this question back when Elon Musk was in 25th place among billionaires. I'm glad that this question looks prescient now. :)

It's important to note that this question can resolve positive without any progress at all. All that would be required is for many 120+ longevity claims to be verified. It is conceivable that there is some population of humans whose genetics permit maximum lifespans slightly longer than Europeans (which currently make up the majority of verified longest lifespans). Given that by 2100, many more countries will have entered the era where birth certificates are a common thing for all citizens, I do not rule this possibility out.

@Jgalt After today, the Republican leadership views him with scorn. So just like late-2015.

There hasn't even been a Nobel Prize for string theory yet, and that theory is much more developed, and is taken far more seriously within the physics community (from what I can gather as a layman). Most Nobel prizes also seem to be awarded for experimental work, rather than theoretical work.

Part of what could make Metaculus great is if it were a place that consistently beat common wisdom due to having a few high-quality predictors that knew "better than the crowd" in their particular domain of study. Here's one way I think it could be done: For questions, or question categories (either could work, I'm still thinking about the details) we allow users to enter a confidence score indicating how confident they are about questions of that type, relative to other categories or questions. Everyone's confidence score would by default be equal for...

@HadiKhan I watched the video and I feel like I'm watching a different video than you. Floyd said very explicitly and frequently he was having trouble breathing (both before and after the knee was on his kneck), and he even cited the knee on his neck as a reason (once it was there). My guess is that he had some trouble breathing and the knee made it worse.

The fact he resisted arrest didn't seem to me to make the response justified, as his resistance seemed very passive rather than active.

@Tamay No, the body does say that the concession must not be rescinded.

This question resolves to the date at which the losing candidate concedes that they have lost the 2020 US Presidential Election, as long as they do not explicitly rescind said concession within 24 hours.

@SimonM I… just… imagine what you could do with $28 million, and now imagine instead being in space for 10 minutes. I often do not understand humans.

A [new announcement from the SENS Research Foundation](https://www.facebook.com/story.php?story_fbid=4275679612467740&id=138424229526653) states, > In June 2021, we began an investigation into the conduct of our Chief Science Officer, Dr. Aubrey de Grey, initially in response to allegations raised by two members of the scientific community. This investigation – conducted by an independent, third-party investigator – remains ongoing. > However, we recently were made aware of communications by Dr. de Grey indirectly attempting to apply pressure on one of...
@(Tamay) It's as good of time as any to link to [Economists Against the FDA](https://www.independent.org/publications/article.asp?id=279), > I have tried to survey all economists’ writings on the FDA and have not been able to find a single instance of an economist defending the contemporary FDA or advocating tighter restrictions.

@Roko You won't look that smart given your public comment. Also, what's worth more, looking slightly smart, or giving accurate information?

The prediction is called off if some other innovations cause a historically exceptional increase in the rate of scientific progress during this period

I feel like this part of the prediction makes it a pretty useless prediction. This is kind of like saying, "Nothing spectacular will happen within the next few decades, conditional on nothing spectacular happening."

@(PeterHurford) Let me put it another way: suppose a user were to ask whether a solar eclipse will happen on December 14th this year. Suppose further that the *intention* of this question was to test whether a New Age apocalypse theory would come true, which predicts that the moon will fall out of the sky on that date, rather than deliver an eclipse. Personally, I’d predict 99%, and I’d sleep just fine with that prediction. But until December 14th, the apocalypse adherents are going to insist they haven’t been proven wrong yet. And so it makes sense to w...
@(Cyrus) [This lifespan.io article](https://www.lifespan.io/news/evolution-wont-stop-aging-any-time-soon-but-medicine-might/) explains, > The study shows that “immortality and everlasting youth are the stuff of myths,” according to The Guardian. The article goes on to say that “an unprecedented study has now confirmed that we probably cannot slow the rate at which we get older because of biological constraints.” Other outlets published similar conclusions, with Futurism saying that the study shows “an ‘invariant rate of aging’ that won’t slow down”. > ...

@Uncle Jeff "The academia-loaded Metaculus community is severely biased toward Democrats"

This is a testable hypothesis. I look forward to testing whether this is actually true... eventually.

@Jgalt Can you explain how this is "virtually inevitable"? My understanding is that there has been essentially no progress in extending maximum human lifespan during the whole course of human history.

Here is a source that compiled a lot of statistics to compare James Holzhauer's performance with Ken Jennings.

@DavidWayne It resolves in 2010 USD, so it doesn’t matter how much the USD inflates or deflates.
