Wouldn't the subset {(a, b) | a,b > 20} be monochromatic? Ed: Perhaps I phrased it poorly, but I think the point was to show that you can always construct a predicate, P over a and b, such that P(a, b) is finitely defined (such as &

The hard part is to show that for any coloring, there's some infinite subset without relying on "well, we can just pick one for each of these infinitely many numbers". I'm pretty sure that the challenge is to prove tha

This might be an off topic question, but how do the results change (if at all) when accounting for the age of the people involved? That is, how do politicians do at predicting the opinions of people +/- 5 years of their own age (which
