The theory makes accurate predictions when the assumption is valid, and does not make accurate predictions when the assumption is not valid. Such assumptions are often the point with which older theories are succeeded by new ones (the general theory of relativity works in non-inertial reference frames as well).
A theory is a rational type of abstract thinking about a phenomenon, ... These assumptions are the elementary theorems of the particular theory, and can be thought of ...
The theory makes two technical assumptions about individuals' preferences over alternatives: Completeness – for any two alternatives a i and a j in the set, either a i is preferred to a j, or a j is preferred to a i, or the individual is indifferent between a i and a j. In other words, all pairs of alternatives can be compared with each other.
The expected utility hypothesis is a foundational assumption in mathematical economics concerning decision making under uncertainty. It postulates that rational agents maximize utility, meaning the subjective desirability of their actions. Rational choice theory, a cornerstone of microeconomics, builds this postulate to model aggregate social ...
Independence of irrelevant alternatives (IIA) is an axiom of decision theory which codifies the intuition that a choice between and should not depend on the quality of a third, unrelated outcome . There are several different variations of this axiom, which are generally equivalent under mild conditions.
Non-logical axioms may also be called "postulates", "assumptions" or "proper axioms". [5] In most cases, a non-logical axiom is simply a formal logical expression used in deduction to build a mathematical theory, and might or might not be self-evident in nature (e.g., the parallel postulate in Euclidean geometry). To axiomatize a system of ...
In practice the politics and theology of the day determined the result of the dispute, but the nature of the controversy was a clear example of how different bundles of (usually implicit) auxiliary assumptions could support mutually inconsistent hypotheses concerning a single theory. In terms of either version of the Duhem–Quine thesis it ...
In social psychology, shattered assumptions theory proposes that experiencing traumatic events can change how victims and survivors view themselves and the world. . Specifically, the theory – published by Ronnie Janoff-Bulman in 1992 – concerns the effect that negative events have on three inherent assumptions: overall benevolence of the world, meaningfulness of the world, and se
