A nomological network (or nomological net) is a representation of the concepts (constructs) of interest in a study, their observable manifestations, and the interrelationships between these. The term "nomological" derives from the Greek, meaning "lawful", or in philosophy of science terms, "law-like". It was Cronbach and Meehl's view of construct validity that in order to provide evidence that a measure has construct validity, a nomological network must be developed for its measure. The necessary elements of a nomological network are: * At least two constructs; * One or more theoretical propositions, specifying linkages between constructs, for example: "As age increases, memory loss increases". * Correspondence rules, allowing each construct to be measured empirically. Such a rule is said to "operationalize" the construct, as for example in the operationalization: "Age" is measured by asking "how old are you?" * Empirical linkages represent hypotheses before data collection, empirical generalizations after data collection. Validity evidence based on nomological validity is a general form of construct validity. It is the degree to which a construct behaves as it should within a system of related constructs (the nomological network). Nomological networks are used in theory development and use a modernist approach. (Wikipedia).

Problems with the Classical Conception of Rationality (John Searle)
John Searle discusses the standard conception of rationality and some of the problems and paradoxes that it gives rise to, including the impossibility of Akrasia (i.e. weakness of will), the impossibility of self-deception, the irrationality of voting, that there must be some odds at which
