Natural frequencies facilitate diagnostic inferences of managers
In Bayesian inference tasks, information about base rates as well as hit rate and false-alarm rate needs to be integrated according to Bayes' rule after the result of a diagnostic test became known. Numerous studies have found that presenting information in a Bayesian inference task in terms of natural frequencies leads to better performance compared to variants with information presented in te...
متن کاملHow to Improve the Diagnostic Inferences of Medical Experts
Women are generally informed that mammography screening reduces the risk of dying from breast cancer by 25%. Does that mean that from 100 women who participate in screening, 25 lives will be saved? Although many people believe this to be the case, the conclusion is not justified. This figure means that from 1,000 women who participate in screening, 3 will die from breast cancer within 10 years,...
متن کاملVisual aids improve diagnostic inferences and metacognitive judgment calibration
Visual aids can improve comprehension of risks associated with medical treatments, screenings, and lifestyles. Do visual aids also help decision makers accurately assess their risk comprehension? That is, do visual aids help them become well calibrated? To address these questions, we investigated the benefits of visual aids displaying numerical information and measured accuracy of self-assessme...

This paper describes in brief Cornell’s interdisciplinary eRulemaking project that was recently funded (December, 2005) by the National Science Foundation.
متن کاملWhy frequencies are natural
Research in mathematical cognition has shown that rates, and other interpretations of x/y, are hard to learn and understand. On the other hand, there is extensive evidence that the brain is endowed with a specialized mechanism for representing and manipulating the numerosities of sets – that is, frequencies. Hence, base-rates are neglected precisely because they are rates, whereas frequencies a...
