We present a simple model of smart money and dumb money. Dumb money tries to learn from market prices whether or not it is dumb. Dumb money's ability to learn depends on its openness to the idea that it may be the dumb money and on its ability to assess the total amount of dumb money in the market. Neither requirement may be met easily in the real world.
