  • Especially in the US, where both parties are globally “right” in both political and financial aspects, a lot of time claiming to be a centrist means that you like capitalism and bombing other countries but you support LGBT causes and are pro-choice. I think, online and especially on lemmy, that the vocal left-wing voices (correctly) see this still as aiding the right but being too cowardly to admit it.

    This also ties back to the MLK quote about the ‘white centrist’ being the biggest obstacle to his movement, because they may say the right things and appear to be helpful but take no action for the movement. By staying centrist and trying to meet in the middle, would lend credibility to the voices on the other side.





  • Do you know the third door is never correct? Because then the probability doesn’t change.

    Scenario 1: You chose 1/2 at first with a 50% chance of being correct, I introduce a 3rd door (but it isn’t a legit possibility), so the actual choice for you is still 50/50 (between doors 1 and 2)

    Scenario 2: If you think it’s possible that 3 could be correct (but it actually never is) then, no, you wouldn’t want to switch. By staying with your first choice has a 50% chance of winning, by switching it only has a 33% chance. But there’s no way to know this ahead of time (because as soon as you know you shouldn’t switch bc 3 is the wrong door, then you’re back in scenario 1)

    Scenario 3: For completeness, let’s say the 3rd door can be correct sometimes. Then it doesn’t matter if you switch or not. It’s a 33% chance of winning either way. If there is a chance it can be correct, then your first choice doesn’t matter at all and the second choice is the ‘real’ choice bc that’s the only time you’re able to choose from all real possibilities.

    The only reason that the Monty Hall problem changes probability in the second choice is because you are provided more information before the switch (that the opened door is absolutely not the one with the prize)





  • Because when you first picked 27, it was 1 out of 100 choices. Then I tell you that you either got it right, or it’s this other number. None of the others are correct, only 27 or 44.

    So you think your 1/100 choice was better than the one I’m giving you now? On average, you’ll be right 1% of the time if you don’t switch. If you do switch, you’ll be correct 99% of the time.

    Another way to think of it is: you choose 27 or you choose ALL of the other 99 numbers knowing that I’ll tell you that 98 of them are wrong and you’ll be left with the correct one out of that batch. One of those clearly has better odds, no?
