Prescriptive decision scientists are concerned with prescribing methods for making optimal decisions. Descriptive decision researchers are concerned with the bounded way in which the decisions are actually made. The statistics courses treat risk from a prescriptive, by suggesting rational methods.

Normative decision theory models the most ideal decision for a given situation. ... Descriptive decision theory takes into consideration outside factors that influence an actor's decisions toward less optimal, less rational ends. Pascal's Wager, for example, addresses descriptive theory.

A theory is aimed at a generalized statement aimed at explaining a phenomenon. A model, on the other hand, is a purposeful representation of reality. ... Another way to link the two and point out differences is, a model is often used to describe an application of a theory for a particular case.

Perception is the process of gathering, organizing, and interpreting of sensory information in order to represent and understand the presented information or the environment. Decision making is the process of identifying and choosing alternatives based on the values, performance, and beliefs of the decision maker.

Descriptive versus Normative Claims. A “claim” is statement that asserts something that could be either true or false. A DESCRIPTIVE claim is a claim that asserts that such-and-such IS the case. A NORMATIVE claim, on the other hand, is a claim that asserts that such-and-such OUGHT to be the case.

The rational decision-making model has important lessons for decision makers. First, when making a decision you may want to make sure that you establish your decision criteria before you search for all alternatives. This would prevent you from liking one option too much and setting your criteria accordingly.

Models are closely related to theory and the difference between a theory and a model is not always clear. Models can be described as theories with a more narrowly defined scope of explanation; a model is descriptive, whereas a theory is explanatory as well as descriptive [29].
