I am not saying it's completely wrong. But half-wrong. Think about it first. Then read the rest of my post.
Okay, here we go. I'll call the Lords L and the non-Lords C for Commoner.
>LLC would result in C immediately knowing he's C and go through the C portal. The other Ls would realize how he came to that conclusion and go through the L portal.
>LCC would result in all of them waiting for a bit. The Cs would then come to the conclusion that neither of them Lords, because then the LLC scenario would have happened and one of them would have gone through the C portal. In that scenario 2 (!) players go through the right portal first.
>CCC would result in all of them waiting for a long time and thinking each scenario through. They would then realize none of them is seeing the LCC scenario, which means all 3 (!) would go through the C portal.
The image would be improved if it said 2 or 3 players would know which portal is right. The only scenario where only 1 player goes through the portal, before the others, doesn't require him to think for long. Therefore that certainly can't be the right answer.
The CCC scenario relies on player 1 thinking his teammates are thinking logically. It also goes a level deeper. It relies on him thinking that his teammates think all of them, including him, are thinking logically. But why then wouldn't they come to the same conclusion as him and also go through the portal?
It's however reasonable to assume that based on human differences someone would be a bit braver or think quicker and would make the first move. But based on that LCC is also a plausible scenario. One C might be a bit quicker than the other C.
I hope I mindfucked you now and made you confused about what scenario is the right one. Just remember what I said in the beginning. Don't start overthinking it now.
