    Wouldn’t it be unlikely an opponent would continue to use the conventional strategy if you played a series of games? After potentially one or two games of losing, they would recognize your pattern of questions and adopt it and then you would not maintain the advantage for the remaining set of games

      Yeah the video title is misleading, because it assumes your opponent is a kid lol. A rational opponent would adopt an optimal strategy to confront you, in which case the first player will win approximately 2/3 of the time (if you do the math out)

    I like the alternate way to play guesswho where you have to ask abstract questions like "does your person look like they would enjoy tapas as a first date" - it's a genuinely funny way to play with friends.

      @TulpechaidoplaysMC It depends on how you interpret the question. Either you are expecting an answer that is one of the attributes, i.e. "red hair", "glasses", or "hat", or you expect an answer that is yes or no. For the latter it is one question since, when answered, you just know the character has atleast on of the attributes, but not which or if they have multiple.

    When my son was 4 I think he came up with the best strategy. He memorized the boards, and I even had both set up different. Then he noticed usually the person he was playing would put their person down on their board right away, or with the first group they put down. He would figure it out almost every time after one question.

      @mkaali there's some memory involved and some luck. For example: "Do either of your people have white hair?" If the answer is "no" you can knock down all the people with white hair. If the answer is "yes" then you have to remember that AT LEAST one of their people has white hair until you have more information..."Do both of your people have white hair?" If yes, now you can knock down everyone that doesn't have white hair. If no, then you know that one person has white hair and the other does not.

    I can confirm that good teachers really shape the way you see their subject. Last year I had this awesome physics/chemistry teacher that was very bubbly, fun, and charismatic. She always taught with passion, and it was very fun. Even for those that weren't doing well! She was very patient and was willing to help everyone understand the concepts. Now I have the complete opposite of a teacher in physics/chemistry, I never hated chemistry until she came around.

    "It's a random process but you do know the group will always look like that" - the teacher says this with such fresh and genuine fascination even though he's taught that perhaps tens of thousands of times. His unwaning passion for the subject he teaches is indeed super contagious, just like the one who made this video.

    The strategy could even be improved one step further if i’m not mistaken.
    Consider u have already reduced the number of people to six (2 turns have passed at a reduction rate of 50% per turn). At this point, there would be still 3 turns left to find the person in a dystopic scenario (reduction to 3, reduction to 2 and finally reduction to 1).
    But there is a problem when u get to three bc it takes the same number of turns to get to 1 (worst case scenario of course) than if u had 4 (u would reduce the sample firstly to 2 and then to 1) so it’s not really “efficient”. Instead, I found that if when u have 6 remaining people u ask about only 2 of them, there’s a possibility of saving one turn.
    -Scenario 1: The right person was within the group of two people u picked and therefore save a turn bc u need only one more turn to determine the solution.
    -Scenario 2: The right person was NOT within the group of two people u picked (hence there are still 4 remaining possible candidates), but since it takes the same number of turns to reduce to 1 from 4 than from 3, no turns were saved, but no turns were misused either.
    Nonetheless, it is also true that when u only have 3 remaining people u have a 33% chance of picking the right one since u are reducing the number of possibilities at a rate of 1 person each turn.
    I haven’t given this that much thought but since it occurred to me while watching the vid i decided to comment this anyways.
    Edit: Nevermind, i was wrong. There is a necessary reduction of 33/66% of the sample in both strategies and it is the same whether to do it when there are 6 or 3 people left. The turn saved that i referred in the original comment could also happen if the player guesses which of the three is the right one when there are 3 candidates left.
    I also tend to talk weirdly so i’m sorry if my reasoning was not understood completely.

    Wouldn’t it be inaccurate to use a bell curve to represent your strategy since it always guarantees a win within five or six guesses exclusively when done properly? In that case, the distribution between number of guesses to win wouldn’t resemble a normal curve, but instead be a single split probability between two outcomes.

    • David Cox
      David Cox 9 сағат бұрын

    You wanna make guesses that cut the available choices in half--or the closest to 50/50. That way you get the same benefit yes or no. If you cut the 24 heads in half each guess you win in 5-6 guesses EVERY TIME!
    2 years later update: I feel like asking “Does your person have white hair or glasses?” isn’t fair. But “Does your person have facial hair?” is totally fair. Beards AND mustaches would count and it’s at least related.

    In blind games I play with the no repeat question rule I just ask questions that apply to my pick, therefore if they dont pick up on that they wont be able to properly narrow down any real answers. It definitely has a positive win rate, but I would guess in the 65-75% range.

      Except it's not accurate. He demonstrates a way to win that he describes as being 80% accurate (though by my math, it's actually about 74%, and only if you go first). It also bugs me that he doesn't talk at all about the statistical advantage in going first.

    this is basically a very similar concept to database indexing. when you are searching a database for something, its much faster to find it if you can order all potential answers, and then the computer tries to figure out if its above or below a random guess. It requires less amount of checks to do it this way than to sequentially check each individual row if its accurate or not.

      I know this is an old comment thread but a lot of you are misunderstanding the type of "or" question he was referring to. Its not an "either/or" question with an answer like "is it 1 or 2?" in which you would answer 1 or 2, its more of "is it one of 1 or 2? (out of 10)" if it is 1 or 2 you say yes, if its 3-10 you say no. So for best results you would ask "is it 1, 2, 3, 4, or 5?" then you could eliminate 50% of the possible choices. Basically your just using the word "or" to phrase the question in a way that you can ask multiple traits in one question.

    Had a teacher in 5th grade that was really new how to make math entertaining. Literally that year the only thing anyone cared about is getting to math. By far the most I learned from a teacher. I don't know how he did it. He was just very upbeat and energetic. I don't think there was any day of that class where I didn't laugh. I practically had an okay teacher in algebra which was better than most. Literally the only 2 times I learned a lot in math class. The rest was learning from online videos and stuff.

    This is all well and good, but you don't take into account that your opponent may change their strategy after a few games once they realize that your strategy is winning. If they model their strategy after yours, the percentage to win becomes much less. Keeping the games to a minimum per person will probably prevent this, but if you play the same person over and over again (e.g. a sibling) they are bound to pick up the strategy and use it against you.
