But there's not a lot we can do if someone decides to intentionally target the brain's weak spots.Download Risk Probability for Mac - Calculate probabilities for. If we really want people to understand a given probability, then we have to play to the human brain's strengths, and adjust how we present the information. In short, we've got a good idea of some of the things that the human brain does when when it comes to probabilities, and an even better idea of all the ways in which it goes wrong. The use of language makes all the difference. Put that way, it's easy to see that you can tell the person who got a positive result in the test that there's still only a ten percent chance that she has cancer. Gigerenzer then rephrased the statistics: if we ignore the negative tests, nine times out of ten, a positive test for cancer is a false positive. With all that information, what do you tell a woman who tests positive about the likelihood they have the disease? For a lot of people in medicine, the question leaves them stumped a typical survey of doctors (and the World Science Festival audience) reveals that there's no single consensus about the probability that the test indicates a real case of cancer.

He described the probabilities associated with a breast cancer test: one percent of women tested have the disease, and the test is 90 percent accurate, with a nine percent false positive rate. The most compelling example he gave was one he used when working in medical education.

Gigerenzer consistently noted that language was important when it comes to dealing with probabilities.

That was the message of Gerd Gigerenzer, who helps train decision makers in how to evaluate probabilities. Instead, the two groups had wildly divergent means, with one half of the audience answering well above the actual answer, the second significantly below.ĭoes all this mean that humans will perpetually remain stuck when it comes to risk and probability? Possibly not, but we have to be careful.

This is a standard "wisdom of the crowds" sort of question, where the mean should be somewhere close to the actual number. Mlodinow divided the audience in half, and asked both halves separately to estimate the number of countries in Africa. A crowd experiment run by physicist Leonard Mlodinow showed how easy it is to manipulate a people's answers to simple questions without doing anything overt. It's relatively easy to run through the probabilities that show which action you should take, but the answer remains counterintuitive-even for those with an exceptional grasp of math.Īnd that's assuming, as co-panelist Gerd Gigerenzer noted, that Monty isn't being malicious. Mathematician Amir Aczel mentioned that many trained mathematicians can't wrap their heads around the Monty Hall problem, in which changing probabilities dictate how you should act on a popular game show. Although Tennenbaum clearly felt that our intuitive feel for randomness was a positive feature, other speakers on the panel noted that human decision-making could obviously get stuck or be manipulated.
