Decision Making I
Rationality in Decision Making
Question | Answer |
---|---|
What are some of the ideas regarding decision making that stem from economics? | Edwards (1954) says that people are intuitive statisticians. We are rational decision makers that make optimal choices to maximize value. |
What is the difference between expected value theory and expected utility theory? | Value theory has to do with monetary value while utility theory has to do with psychological value. |
How do we test whether we're rational? | Decisions correspond to statistical equations, consistency, and transitivity. |
Describe the certainty effect | Bets and probabilities. Expected value calculations show that first choice in all situations is always higher. When people have two options and one guarantees a gain, that option will almost always be chosen. |
Lichtenstein and Slovic (1973) study on differing bets demonstrated preference reversal among participants. What does this mean? | A tendency to prefer one alternative when a set of alternatives is presented simultaneously and evaluated jointly but to prefer a different one when the same alternatives are presented in isolation and evaluated separately. |
Tversky and Kahneman's (1981) study about the unusual Asian virus successfully demonstrated the framing effect. What is the framing effect? | The phenomenon in which people react differently to a particular choice depending on whether it is presented as a loss or as a gain. |
Another example of the framing effect can be seen in the custody battle example. Why does the situation end the way it does? | Parent B gets sole custody based on the wording of the problem. |
What is the attractiveness effect in terms of decision making? | We will choose the most appealing between multiple options. Can be heavily influenced by the choices available. |
What are sunk costs? | Retrospective cost that has already been incurred and cannot be recovered (boring movie example). |
