If the two alternatives are x and y, the following are the possible pairwise comparisons: The agent prefers x over y: "x > y" or "xPy" The agent prefers y over x: "y > x" or "yPx"

Therefore, revealed preference is a way to infer the preferences of individuals given the observed choices. It contrasts with attempts to directly measure preferences or utility, for example through stated preferences.
