  • OK, let’s see the evidence for that assertion.

    Using prediction markets to estimate the reproducibility of scientific research - PMC

    There’s one.

    But obviously it’s not a guarantee if you don’t know what you’re doing. We also have documentation on where these methods fall short, such as when it’s based on exponential growth, rare events, or something else that humans are bad at understanding. Infectious Disease Forecasting.

    But again, good statisticians are prepared to address those things.

    And you have no idea of the mechanisms that shape that market.

    That’s even better. If I don’t understand the mechanisms shaping the market, I won’t be able to correctly identify predictive variables for my model. In that case, I would be better off trusting the prediction market.

    Obviously it would be better if the person building the model understood the mechanisms… but that takes time and money. If you’re managing 30 models, that might not be worth it.

    If the contract isn’t something that meets the criteria for an efficient market, then yeah, it’s not something that can be used to give reasonable probabilities.

    But for something like, winner of the democratic presidential primary, or the proce of gold in a month… the it’s genuinely a better predictive model than what a statistician would be able to come up with.

    It doesn’t provide anything beneficial to anyone but its owners.

    For statistics purposes, it gives me something incredibly beneficial. Simply by knowing the price of a contract, I can know with decent accuracy how likely something is to happen.

    If you’re not in the field, you wouldn’t necessarily appreciate how valuable that is.



  • Communism always ends with corrupt, power hungry dictators.

    What if head government positions in general are attractive to corrupt, power hungry dictators?

    The Weimar Republic wasn’t communist, and it got a corrupt, power hungry dictator.

    The United States isn’t communist, and it’s dealing with a corrupt, power hungry dictator.

    Israel isn’t communist, and it’s dealing with a corrupt, power hungry dictator.

    I wonder if maybe there are other factors in play that you aren’t considering.

    always

    Always? Are you sure? Let’s say there’s a corrupt, power hungry person looking for a government spot. How would communism make it easier for the person to get into power, than in a capitalist system?


  • Well, it’s the aggregated opinion of people who use the site. Kalshi doesn’t set the price; people making the bets set the price based on the odds others are willing to accept.

    There’s a sampling bias for sure, but since the odds given for this bet are based on how much people are willing to pay for that bet, this gives a very good approximation for how people actually feel about something.

    It actually ends up being more reliable than most opinion polls in that way.


  • For jalapeños and other peppers, the pithy center is where most of the pungency comes from. It’s also more bitter than the rear of the pepper. If you chop into quarters lengthwise, it’s easy to cut the seeds and pith away from the flesh. You’re the left with a milder, sweeter result.

    … in case you’re in an experimental mood.



  • I don’t want a one-time, 5% wealth tax. I want a recurring wealth tax. At 0.5%, such a tax outpaces the one time 5% in ten years.

    I would settle for one time 5%… but it’s just so short-sighted. 5% in one sudden movement is actually a big ask… and are we actually going to be able to pull that off more than once?

    A recurring wealth tax 1) is better in the long-term, 2) is less disruptive to the stock market (which we should care about, as long as this is the sustem we have) 3) makes for a more predictable economic environment, so people with money might actually still want to live in CA.
