Good idea, but maybe think of making something harder?

Yeah, harder. I got 100% in around two minutes :) I guess people just click a random thing without looking on the description and questions. I'm an exception :)

Yeah, it seems that most people just click the first four in order without paying attention. 😂

But this actually gives me an idea for another quiz.

The answers for 5 and 6 don't really make a ton of sense because by the same logic, 6 could be true if 5 is false, and it doesn't really change the outcome of the rest of the quiz (I think it does create a paradox for #8 but not sure)

Good quiz tho - got 14/14 on the second try after choosing 6 instead of 5 on the first attempt

Yes, statement 8 determines which of 5 and 6 is true. It can only work one way. :)

So the logic is that, based on no. 8, two of 6, 7, and 8 are true. And because 5 and 6 directly contradict each other, they cannot both be false, which means no. 7 must be false. And no. 6 must be false because if it were true, then 8 would be false. But, under those conditions, 8 can't be false, because no. 6 being true makes 7 and 8 both false, but 8 says that at least two of 6 through 8 are false, so it would in that situation be simultaneously true and false, which is impossible. So 8 has to be true, which means 6 has to be false, and that's how you discern between 5 and 6.

Is that right? That's the only one that tripped me up. I got the first 13 correct and then just took a guess on the last one because I hadn't sussed out the second row. But I think I got it now.

This makes me want to read Godel Escher Bach again. Good stuff.

Imo, the solvability of statement 8 shouldn't affect the verity of statement 6, but: Maybe I'm being too nit-picky...

definitely confusing because by saying "this is the first false statement", we are told that it is false, but it is true that it is the first false statement, so I chose true.

But it’s not the first false statement. There is no scenario where it’s the first false statement. So it must be false, and a question before it must be false.

It says “The first 4 statements are true”, so you shouldn’t you click the 3rd and 4th buttons too?

The fourth statement claims to be the first false statement, so it can’t be true no matter what. That makes statement 3 automatically wrong.

But where does it say that no. 5 is true?
Dimby

For #5 and #6, one has to be true, and one has to be false. 7 says they're both false, so it's automatically false. #8 says that at least two of 6, 7, and 8 are false. This creates a scenario where #8 cannot possibly be false, since it becomes true because it looks at itself as one of the possible false options, and 7 is already obviously false. This means that 8 has to be true, and since two of 6, 7, and 8 must be false, 6 is false. Since 5 and 6 must be opposites, #5 must be true.
