ABSTRACT
Judgments of probability or frequency are not conjured from thin air. They are usually made after some exposure to the domain in question. In particular, we often make judgments after learning something about the structure of the environment. It is natural to expect that the nature of this prior learning shapes the judgments we make; not just in the trivial sense that prior exposure provides us with data on which to base our judgments, but also in the deeper sense that the mechanisms that operate during learning are active in the judgment process itself.
