Abstract: In a variety of choice environments, perception is both noisy and coarse. That is, the agent perceives the true ranking of the objects of choice with error; and, in addition, the perceived values can only be discriminated coarsely. Reasons for coarse perception include limitations in sensory perception, memory function, or the communication technology used by expert advisors.
