    I just saw this on Reddit a few minutes ago and this is brilliant! I'd love to see more. The content was legitimately interesting and quite unique and I think the thing was produced well... No problems with pacing, I never felt bored. Animations clean and helpful. Great audio quality. Overall standout job!

    Nice job! Since you asked for feedback, I have two minor criticisms: 1) I like your use of color, but would like arrowheads in addition, and 2) the pace was a bit fast for me.

      Thanks a lot for the feedback! I will certainly be using arrowheads for directed graphs in the future, no idea why I didn't use them in this video.
      Pacing is always tricky but In future videos I'm planning to run through the script at a few different paces to see which works best.
      Thanks again and I'm glad you enjoyed the video!

      Hey thanks a lot! Support like that is a massive encouragement. I've got a couple of videos in the pipeline at the moment (Should be out soon) which I think are going to particularly interesting! :D

    In what circumstance would we know how many people were telling the truth? How would we be able to solve this if we had no idea who was telling the truth?

  • @tvjjerome
    @tvjjerome 4 роки тому +2

    I’m a bit confused from the introduction where only one person is telling the truth. Is there a logical reason that only one person is telling the truth, or is it just some extra information given?

    • @isaacprosper6295
      @isaacprosper6295 4 роки тому

      Also why is it that one person accussss one and others accuse all ,what if you're in a case where all accuse each other equally or don't accuse any or 2 thieves are responsible🤔

  • @YoutubeChannel-gw4zr
    @YoutubeChannel-gw4zr 3 роки тому +1

    The people saying they’re not the thief could be talking outside the group of suspects, and anyways I don’t really get how it’s determined who’s the thief because everything can be a lie/with false dichotomies(not just true or false) with no indication of any direction at all. Either I just don’t get what you were explaining, or there are flaws with some of the reasoning. I’d say what gives away who the thief is from the person who blames someone else... either the person they are blaming is a thief or they are the thief themselves to misdirect who the attention is on. But also there might be a boss or friend that they can’t blame therefore a scape goat. I don’t think anyone can determine who is the real thief unless the math is done on the actual psychology of the person or something along those lines. People like to blame people if there is any sign to blame somebody or just stay quiet. Even people blaming themselves could just be doing something for the team. They let themselves get the blame even when they didn’t do it.

    Why did you remove the text in 0:24 to 0:49? Making it very difficult to follow the logic with some text missing

  • @kieranosullivan4966
    @kieranosullivan4966 3 роки тому

    I think this problem should be re-worded Saying "I am not the thief" is not thie same thing as "B or C is the thief thief" or "A or B is the thief thief". Each edge should be arrowed and labeled to make this clearer. Anyone disagree. This would make the problem easier to solve as it does not require the leap to assume that "I am not the thief" = "one of the other two is the thief".

    What if in a real scenario there is more than one thief,also you logic assumes that one person accuses one while many accuse two or more,what if all thieves just say I'm not the thief

  • @ioleki1571
    @ioleki1571 3 роки тому

    shouldn't the amount of people telling the truth be 2 instead of 1 for the first example. If there is only one thief there should be 2 telling the truth

    • @scienceplease3364

      This is an assumption . I may make a video in the future addressing what happens when you relax that assumption!

  • @vilecypher

    You could've made this into a 30 minute video and it would've been enjoyable. Science and math vdieos dont have to follow the mr beast rules for videos. Those rules are only for low attention audience. You would've had alot of views if you didnt rush to fill in your time limit
