Base-rate training without case cues reduces base-rate neglect.
Base-rate neglect is a persistent phenomenon in which subjects do not place sufficient weight on the probabilities of occurrence of relevant events. Two experiments with college students support the hypothesis that base-rate neglect may be minimized by providing base-rate training in the absence of case, or witness, cues, prior to introducing (or reintroducing) these cues. In Experiment 1, the ...
متن کاملBase-Rate Neglect and Imperfect Information Acquisition
Base-rate neglect is a robust experimental finding that individuals do not update their prior beliefs according to the Bayes’ rule and, typically, underestimate their posterior probabilities. Another empirical finding is that individuals often do not acquire information even when there are no strategic considerations and the cost of new information is justifiable economically. This paper combin...
متن کاملTesting the Ecological Rationality of Base Rate Neglect
What simple learning rules can allow agents to cope with changing environments? We tested whether a rule that neglects base rates of events in the world — something that is usually considered irrational — could be as successful as Bayesian inference — the usual standard of rationality — in making cuebased predictions about events in time-varying environments. We focused on environments in which...
متن کاملSupport for a Deliberative Failure Account of Base-Rate Neglect: Prompting Deliberation Increases Base-Rate Use
People often base judgments on stereotypes, even when contradictory base-rate information is provided. It has been suggested this occurs because people fail to engage or complete deliberative reasoning needed to process numerical base-rate information, and instead rely on intuitive reasoning. However, recent research indicates people have some access to this base-rate information even when they...

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
