AMBIGUOUSLY

What fraction of active users will switch back to dark mode?

I've struggled to get my "prediction" in the right format, but I think this is about as close as I'm going to get. My prediction isn't as much "my" prediction as "what I think the market probabilities are" and my view is "the market is broadly sensible". I thought this question was going to be pretty sensitive to kurtosis, so rather than modelling it as a lognormal random walk, I fitted a [Heston model](https://en.wikipedia.org/wiki/Heston_model) to the Deribit option prices. Having spent a bunch of time collecting the prices and fitting the model. My...

Given Dobbs counts, worth noting FantasySCOTUS is currently forecasting a 6-3 reversal (ie this question resolving positive)

There's something fairly nasty about predicting maximums on Metaculus. The "correct" distribution is a mixture of discrete (probability we've already had the maximum) and continuous (probability the maximum is yet to come). (The distribution also tends to be very not-symmetric, which is always quite hard to predict using the Metaculus input).

@(alexlyzhov) If anyone is interested in calculating this for themselves, they can look at prices [from Deribit](https://www.deribit.com/main#/options?tab=BTC-31DEC21). The quick and dirty calculation would be to look at the 80k/120k call spread (divided by 40k). Currently this is: * (14,700 - 9,750)/(40,000) = 4,950/40,000 = 12.4% A barely more sophisticated way to do this would be to calculate a tight call spread using Black-Scholes around 100k. To avoid worrying about (fairly confusing) interest rates, we can use the forward from Deribit: 54,400 an...

> Assuming the default risk is really 4%, I find it interesting that the 10-year Treasury is only paying interest of 1.5%. https://www.cnbc.com/quotes/US10Y --> There are a lot of things I do not understand about investor behavior, and people buying up Treasury bonds at such a low yield is one of them. @johnnycaffeine @MaciekK @JosephLamps > This seems like the kind of thing that serious financial forecasters would be interested in - is there any way to infer this from eg the interest rates they’re paying on US government loans, for example? @holoman...

Including tests in this question seems like a bad thing for two reasons: 1. It doesn't get at the heart of the issue (will a nuke be detonated in a way which is bad news for humanity) 2. People looking at the forecast (which I assume will be much higher than the chances of an attacking nuke) are likely to be misled by a high forecast. Anyway, from scanning wikipedia post-2000 there were tests in: 2004(?), 2006, 2009, 2013, 2015, 2016, 2017, 2020(?) Counting questionable tests has half, the base rate for this could be 7/21 ~33%. Seems a good way to sc...

POSITIVELY

@(PeterHurford) Of course. The probability of a random walk starting at 0 reaching a point \(x\) after time \(t \) with volatility \( \sigma \) is [given by](https://quant.stackexchange.com/a/12797/12046): \[ \mathrm{erfc}\left( \frac{x}{\sqrt{2t \sigma^2}} \right) \] To calculate \(\sigma\), I downloaded data from [CoinDesk](https://www.coindesk.com/price/bitcoin) and looked at the daily closes. I then took the 0-mean standard deviation of the daily log returns: \[ \sigma^2 = \frac{1}{\text{num days}} \sum_{\text{all days}} \left ( \textrm{log} \le...

[This website](https://www.wismuth.com/elo/calculator.html#name1=Carlsen%2C+Magnus&name2=Nepomniachtchi%2C+Ian&first_move=player1&formula=logistic&best_of=14) gives a 77% chance to Carlsen for the first 14 games, 12% to Nepo and 10% chance of a tie (and hence tiebreakers). (Using current Elo ratings) Using the same odds (per game) for the tiebreaks, Carlsen has an ~75% chance of winning the tiebreak. So call this 85% chance of retaining the title. I think this method drastically underestimates the number of draws in World Championship matches. The last...

I'm sure I'm just embarrassing myself at this point, but despite all the evidence I think this is starting to look like a Metaculus special. 1. Cases in Scotland already peaked ~2.5 weeks ago. The latest wave started there around ~3 weeks earlier than in England. 2. Cases in the UK look like they are *starting* to peak. (Low confidence in this, but I can persuade myself they've already peaked) 3. Current case level is "just" sufficient to cause 100 deaths/day: Currently cases are converting to deaths at a rate somewhere between 0.15 and 0.2%. This wo...

"Did people simply fail to update their prediction?"

is usually the explanation

That's a pretty brutal base rate
