Suppose I have a blind man and a sighted man. The blind man has a cataract that could be repaired with surgery. I tell them that a jar contains a very large number of pebbles, all of them are either green or blue, and there are twice as many of one color than the other. I pull out a random pebble, which turns out to be green, and show it to both the men. I ask them to write down what they think the probability is that the next pebble I pull out will be green. The sighted man writes 51%; the blind man writes 50%. Who is more rational?
Does it count if I want to call the blind man irrational for not having repaired his eyesight? Or are we pretending he has a good reason? Or would the intended example be the same if he had irreparable blindness?
