Conjunction Error Fallacy

am particularly fond of this example [the Linda problem] because I know that the [conjoint] statement is least probable, yet a little homunculus in my conjunction fallacy example head continues to jump up and down, shouting at me—“but she can’t conjunction fallacy psychology just be a bank teller; read the description.” Stephen J. Gould[1] The most often-cited example of this fallacy originated

with Amos Tversky and Daniel Kahneman:[2][3] Linda is 31 years old, single, outspoken, and very bright. She majored in philosophy. As a student, she was deeply concerned with issues of

discrimination and social justice, and also participated in anti-nuclear demonstrations. Which is more probable? Linda is a bank teller. Linda is a bank teller and is active in the feminist movement. The majority of those asked chose option 2. However, the probability of two events occurring together (in "conjunction") is always less than or equal to the probability of either conjunction fallacy and representative heuristic one occurring alone—formally, for two events A and B this inequality could be written as Pr ( A ∧ B ) ≤ Pr ( A ) {\displaystyle \Pr(A\land B)\leq \Pr(A)} and Pr ( A ∧ B ) ≤ Pr ( B ) {\displaystyle \Pr(A\land B)\leq \Pr(B)} . For example, even choosing a very low probability of Linda being a bank teller, say Pr(Linda is a bank teller) = 0.05 and a high probability that she would be a feminist, say Pr(Linda is a feminist) = 0.95, then, assuming independence, Pr(Linda is a bank teller and Linda is a feminist)= 0.05×0.95 or0.0475, lower than Pr(Linda is a bank teller). Tversky and Kahneman argue that most people get this problem wrong because they use a heuristic (an easily calculated procedure) called representativeness to make this kind of judgment: Option 2 seems more "representative" of Linda based on the description of her, even though it is clearly mathematically less likely.[3] In other demonstrations, they argued that a specific scenario seemed more likely because of representativeness, but each added detail would actually make

This usually happens when it is easier to imagine two events occurring in a combination than occurring alone. Consider the following statements and decide which is more likely: 1) http://www.alleydog.com/glossary/definition.php?term=Conjunction%20Fallacy%20(Conjunction%20Error) Carol has several students that practice the piano everyday; or 2) Her students that practice the piano everyday are proficient.
