Quote (Tracy P. Hamilton @ May 31 2012,11:47) | Daniel Kahneman, Thinking, Fast and Slow.
A cut and paste from an Amazon review: "Here is one final example from Kahneman's work of some of the concepts the reader will encounter in this book. Suppose that Linda is 31 years old, single, outspoken, and very bright. In college, she majored in philosophy. As a student, she was deeply concerned with the issues of discrimination and social justice, and she also participated in anti-nuclear demonstrations. Which is more probable?
1. Linda is a bank teller. 2. Linda is a bank teller and is active in the feminist movement.
According to Kahneman, about 85% - 90% of undergraduates at several major universities chose the second option, that Linda was a bank teller and active in the feminist movement. However, this is an example of the "conjunction fallacy," since the probability of two events occurring together (in conjunction) must necessarily be less than the probability of either event occurring alone. Put simpler, the probability that Linda is a bank teller must be greater than the probability that she is a bank teller and active in feminist causes. (To be complete, Kahneman points out that there are critics of the Linda experiment who, for example, question whether it is reasonable for test subjects to understand the word "probability" as if it meant "plausibility.")"
The book subtitle: Why people are IDiots. :) |
Finally I get one right!
