### Re: Blue Eyes with Superrationality

No that is just normal logic, reasoning about the thinking of other perfect logicians isn't outside of normal logic. Superrationality is taking getting the same answer into account like in things like symmetrical games. Like concluding in the prisoner dilemma that you should cooperate. It isn't log...

### Re: Blue Eyes with Superrationality

Going back I'm noẁ unsure where you think you are using superrationality. There is no superrationality necessary in any scenario with more than 2 blues to determine that nobody sees less than 1 blue, thinking about what others see or what conclusions they arrive at does not require superrationality...

### Re: Blue Eyes with Superrationality

So how is that not an needlessly convoluted way of saying that people know the blue people they see see one less blue than the brown people they see? It doesn't only apply to blue eyed people. The whole point of using arbitrary individuals with indeterminate personal colors in my original example i...

### Re: Blue Eyes with Superrationality

Two of them can indeed agree on a number, if you get three to agree to a number that would be impressive. Example case: A and B have brown eyes, C has blue eyes. A+B as pairing=1, A and C=B and C=0. Show how they can arrive at the same minimum. Otherwise the difference of one is what causes all pla...

### Re: Escape the bear in the circle?

This is because your strategy would push the person closer and closer to the boundary. Even while moving in a circle, the bear can position itself to force the tangential direction of the prey's circular path to move towards the boundary. The tangential direction of the person's path, by definition...

### Re: Blue Eyes with Superrationality

"This means that everyone I see can make the following assumption about people they see (denoting this group as we because it includes me).We will see a minimum of[/u] x-2 blues and y-2 browns based on my seeing x blues and y browns." is wrong. You can't combine the minimums because peopl...

### Re: Blue Eyes with Superrationality

Even though they all can agree that there is at least one blue-eyed person on the island, they don't mean the same thing when they say that. It really means, "amongst the N-1 people that are not me, there is at least one blue-eyed person". That statement is self-referential, and refers to...

### Re: Blue Eyes with Superrationality

General response to everyone: The important thing here is that between any two individuals, there is only two unknowns total. If we just ignore those unknowns, we can still deduce the other's conclusions about us, hence the -2. This logic applies to every individual that you see and you know they wi...

### Re: Escape the bear in the circle?

It seems like you are saying the bear is smarter than the protagonist? If so, then the bear should always win as long as it is a finite space. If the bear is forced to follow some specific algorithm, then a "smart" protagonist should be able to avoid it indefinitely. The strategy for the ...

### Re: Blue Eyes with Superrationality

Superrationality has already been tried on Rethinking Blue Eyes - A Logic Puzzle I actually read that first. It seems like he misunderstood the concept of superrationality. You do not need to plan ahead. Superrationality depends on like minds given the same information coming to the same conclusion...

### Blue Eyes with Superrationality

I believe the solution might be incorrect since it is based on rationality as opposed to superrationality, at least based on my understanding of superrationality. <EDIT 2> Refer to my second post for a clearer explanation. I will leave my original post as a spoiler here.</EDIT 2> <EDIT 3>For simplic...
