One is forced to assume that ordinary people have the computational capabilities and statistical software of econometricians.

If the system exhibits a structure which can be represented by a mathematical equivalent, called a mathematical model, and if the objective can be also so quantified, then some computational method may be evolved for choosing the best schedule of actions among alternatives. Such use of mathematical models is termed mathematical programming.
george dantzigSuppose that the organism is given the problem of determining the analysis of a stimulus at a certain level of representation e.g., the problem of determining which sequence of words a given utterance encodes. Since, in the general case, transducer outputs underdetermine perceptual analyses, we can think of the solution of such problems as involving processes of nondemonstrative inference. In particular, we can think of each input system as a computational mechanism which projects and confirms a certain class of hyputheses on the basis of a certain body of data.
jerry fodorAlgorithms are the computational content of proofs.
Broadly stated, the task is to replace the global rationality of economic man with a kind of rational behavior that is compatible with the access to information and the computational capacities that are actually possessed by organisms, including man, in the kinds of environments in which such organisms exist.
Herbert SimonIf (...) we accept the proposition that both the knowledge and the computational power of the decision maker are severely limited, then we must distinguish between the real world and the actor’s perception of it and reasoning about it.
[I]t is particularly encouraging to see the growing number of computational studies being conducted at the cellular and molecular levels. Perhaps no where else in neuroscience is the risk of getting lost in the trees and separated from overall brain function as great.
