Rational Choice Theory

‘Rational choice is the sociological theory with the greatest explanatory power.’ Discuss.

“Rational-choice theorists want to explain behavior on the bare assumption that agents are rational. This assumption includes the hypothesis that agents form rational beliefs, including beliefs about the options available to them. There is no need, therefore, to classify the determinants of behavior as either subjective (desires) or objective (opportunities). Rational-choice theory is subjective through and through.” (Elster, 2015)

"An action is rational, in this scheme, if it meets three optimality requirements: the action must be

  1. optimal, given the beliefs;
  2. the beliefs must be as well supported as possible, given the evidence;
  3. and the evidence must result from an optimal investment in information gathering." (Elster, 2015)

Limits of Rational Choice Theory

Prof Herbert Simon, Nobel Prize winner, argues that decisions are hard because of factors such as imperfect information, uncertainty, and time constraints, which all affect and limit our rationality, and therefore our decision-making. Led to the concept of Bounded Rationality, Simon (1957)[^2] coined the term to explain that rationality has its limits and is limited by factors e.g.  1) difficulty of the problem, 2) cognitive capability, and 3) time available, among others.

Political polarization

Political polarisation is the process by which the political opinions of a population become more and more divided along two opposing sides. This can happen on a variety of issues, but it is most commonly seen in two-party systems.

There are many different theories about what causes political polarization. Some of the most common explanations include:

Baldassari & Bearman (2007) developed a model of political polarization that suggests that it is driven by two factors:
