The development of heuristics in children: Base-rate neglect and representativeness Samantha Gualtieri (sgualtieri@uwaterloo.ca) & Stephanie Denison (stephanie.denison@uwaterloo.ca) University of Waterloo, Department of Psychology Abstract This paper examines the development of the representativeness heuristic in early childhood. It is used when we judge the probability that an object or event A belongs to class B by looking at the degree to which A resembles B. When we do this, we neglect information about the general probability of B occurring (its base rate) (Kahneman & Tversky, 1972). Consider the following problem: Thus, base-rate neglect arises due to the representativeness heuristic, in which people assume that each case is representative of its class. So, for instance, people watching a taped interview with a prison guard with extreme views will draw conclusions about the entire prison system based on this one interview -- even if they were told in This article illuminates the base rate fallacy, also known as Insensitivity To Base Rates and goes on to show how it affects our decisions and outcomes.
