You have a pleasant garden and your house is not too large; so if the weather permits, you would like to set up the refreshments in the garden and have the party there. In academic settings, game theory focuses on logically deriving predictions of behavior that are rational for all players and seem likely to occur. Mathematical and statistical models can be employed in assessing what should be the optimal decision, psychology and philosophy on the other hand, suggest the likely outcome using human factors and behaviours. Normative decision theory: provides guidance for making decisions given a set of values. While mathematics and statistical models determine what the optimal decision should be, psychology and philosophy introduce factors of human behaviors to suggest the most likely outcome. Chapter 18 Decision Theory. If you still have questions or prefer to get help directly from an agent, please submit a request.
