A Model Decision

Posted on July 25, 2007. Filed under: Uncategorized |

Even if you are a procrastinating, messy, and unorganized person you still use models to take short cuts. Whether you are driving along and see a side road, or you are write down a list to make it through the grocery store faster; everyone makes use of heuristics. Decision making is not any different. An article by Sloman and Hagmayer titled: The causal psycho-logic of choice states that “good decision making generally depends on how actions are causally related to outcomes.” (p.407).

By employing a simple model to analyze how possible actions can affect outcomes, we are better able to sort out which choice to make. Sloman and Hagmayer call this “causal reasoning”, and then use the Bayes nets model to illustrate:
