[21] Another example is that decision-makers may be biased towards preferring moderate alternatives to extreme ones; the Compromise Effect operates under a mindset that the most moderate option carries the most benefit. But critics argue that this is the extreme manifestation of rationality and it is too difficult to apply in reality. In other words, conflict arises between rationality and reality or the general welfare of the bodypolitic. Modern approach such as behaviouralism of Easton or structural-functionalism of Almond heavily relied upon empirical analysis and the decision-making theory could not keep itself away from this type of approach. 8. Most decision-making theory has been developed in the twentieth century. [15] It is also described as cost-benefit decision making since it involves the choices between rewards that vary according to magnitude and time of arrival. Margaret Thatcher was the P.M. of Britain during the period 1979-1990. The decision-making is a process and passes through a number of stages. Serious and considerable thought is invested for a proper decision. The revival of subjective probability theory, from the work of Frank Ramsey, Bruno de Finetti, Leonard Savage and others, extended the scope of expected utility theory to situations where subjective probabilities can be used. (2) If the decision is partly successful, the decision-makers start to investigate the causes of such results and if they feel that there are reasonable grounds of partial success and partial failure, then in that situation they seriously think about revising the decision keeping the causes of failure in mind. On what basis the authority starts to evaluate the decision which has been implemented? Number of factors play important role in the initiation of decisions. About the stages in decision making, Simon identifies three criteria: (a) Intelligence: Searching for problems, and identifying and defining problems that demand action. Laibson's quasi-hyperbolic discounting). Implementation of decision is the third stage of policy. So Snyder’s theory does not offer us a complete picture about decision-making process. Herbert Simon once said: a theory of administration should be concerned with the processes of decision as well as the processes of action. In conclusion few more words may be stated. Some decisions are difficult because of the need to take into account how other people in the situation will respond to the decision that is taken. The basic idea of the rational actor model is derived from economic theory and utilitarianism. William Glasser founded this term from a book with the same title. The head of the state, Prime Minister, Foreign Minister etc. If it is abandoned a new policy is being imitated to replace the old one. During the heyday of Cold War period Washington was at loggerhead with Moscow without any valid reason. A decision is initiated, formulated, implemented and finally evaluated. create pressure on the authority to take a decision in order to give relief to the people or to meet their demands. Rational actor model, Incremental model, Bureau­cratic organisation model and Belief system model. • Akerlof, George A.; Yellen, Janet L. (May 1987). The bureaucrats and other policy makers formulate policies for agencies and various governmental departments. Now we shall focus our attention on Snyder’s approach to the study of political science which is commonly known as decision-making theory or approach to the study of politics. As far as decision making in nursing is concerned, all decision making theories are quite relevant and effective for different given circumstances. In this way there is a clear dichotomy between formulation and implementation. The decision-making approach is not without any limitations. Conclusion: Decision-making theory is one of the contemporary theories that have been built during the mid-20 th century. Some of the concepts of decision making meant for the public administration have also their strong bearing in political science. It is generally observed that in the present day world system domestic policy cannot be separated from world politics and a policy maker must keep this in mind. Since these constituted the bases of decision-making process the decision itself failed to be imperfect and defective. are actively or inactively involved in the social activities. The decisions are made to serve definite purposes/purpose.

What is Decision Theory Approach? This literature review of decision making (how people make choices among desirable alternatives), culled from the disciplines of psychology, economics, and mathematics, covers the theory of riskless choices, the application of the theory of riskless choices to welfare economics, the theory of risky choices, transitivity of choices, and the theory of games and statistical decision functions. Richard Snyder has maintained that in every society there is political action and behind every action there is the role of human activity. However, this sort of occurrence is unavoidable. 2.
