  • hahahh so much fun.

  • @WoWDart Saying 'nobody is a truth teller' would made sense in the context of the question and at the same time it would be a lie. Imagine you asked the truth teller something similar - "Who is over 3 meters tall?" He would truthfully say - "nobody".

  • @WoWDart I get it, but it does fit to Q#2!

  • @TheOpposedMan That doesn't work because those answers do not correspond to the question asked. The ‘who’ implies a single person. “Everyone is not the TT” would not be a lie. It is true that everyone is not the TT. “There is no truth teller here” would indeed be a lie, but it does not fit to Q#2, because you ask ‘Who.’ The Toggler must answer the question with a statement regarding a single person.

  • @khanacademy Please, correct if I'm wrong, but I think I found a mistake on this Brain Teaser. When you ask the truth toggler (the one who said no to the first question) who is NOT the truth teller, he is obligated to lie, right? So, he can simply say: everyone is not the truth teller, or there's no truth teller here. In this case, he would be lying and you could not be sure yet.

  • @Ultraman221 This is kind of a problem with all of his videos. I'm glad to see someone agree for once.

  • It took you 4 minutes to explain what a toggler is. Please hurry the fuck up.

  • @contourplot shut ..... should

    spelling mistakes... you can keep them

  • I´m not quite sure what kind of question are allowed and what answers the characters can give, but what if I asked one of them " who´s gonna respond to my question the same way as you do? ". A thruthteller would tell me the name/position/or piont at another thruthteller, while a liar shut name another liar, but (since he´s a liar) names a thruthteller.

    regardless to their state, even if thruthteller himself theire nomination is a currently thruthteller who I can simply ask. -someone sees a probl

  • @sheepwshotguns and how can you distinguish candidate 1 (nominated after q1) or candidate 2 as the truthteller
