Base rate information social psychology

In probability and statistics, base rate generally refers to the (base) class probabilities unconditioned on featural evidence, frequently also known as prior probabilities. The base rate fallacy, also called base rate neglect or base rate bias, is a fallacy. If presented with related base rate information and specific information, the mind tends to ignore the former and focus on the latter. Base rate neglect is a specific form of the more general extension neglect. Psychology Definition of BASE RATE: in statistics, the probability by which change influences a phenomenon to a certain degree. The changed condition (or variable) determines the degree to wh Sign in

Psychology Definition of BASE RATE: the naturally occuring rate of a phenomenon in a population. This is typically compared with the rate of a phenomenon when influenced by a variable to dete Sign in In general, a base rate is the probability of some event happening. For example, your odds of being struck by lightning in your lifetime is currently about 1 in 12,000 and your odds of developing a brain aneurysm — 1 in 50. A more narrow definition of base rate: the probability of an event happening without intervention. A base rate fallacy is committed when a person judges that an outcome will occur without considering prior knowledge of the probability that it will occur. They focus on other information that isn't relevant instead. Imagine that I show you a bag of 250 M&Ms with equal numbers of 5 different colors. Base rate information Constructing hypothetical scenarios as an estimate of how something will turn out. The easier a particular scenario comes to mind is used to judge the likelihood of it occurring and affects our behavior. base rate heuristic. A mental shortcut which helps us make a decision based on probability. Example: Imagine that I live in a big city and hear an animal at night. I'd assume it's a dog, not a wolf, bc statistically a wolf is very unlikely. Finally, the base-rate heuristic is a mental shortcut that helps us make a decision based on probability. This is when we make a snap judgment based on our knowledge of how likely something is to

The final type of heuristic we'll discuss in this lesson is the base-rate heuristic, a mental shortcut that helps us make a decision based on probability.For an example It is suggested that base rate information lacks impact because of its abstract, pallid nature. In a demonstration of the inefficacy of abstract information, undergraduates were given mean course evaluations based on ratings of students who previously took the courses. This information had little impact on course choices. The standard Engineer-Lawyer problem (Kahneman & Tversky, 1973) points to the failure of reasoners to integrate mentioned base-rate information in arriving at likelihood estimates. Research in this area nevertheless has presupposed that participants respect complementarity (i.e., participants ensure that competing estimates add up to 100%). A survey of the literature leads us to doubt this

The key issue for social psychologists, then, is to understand when the base rate fallacy is likely to emerge and when it is not. At least four major factors are known to moderate people’s use of base rates in judgments and decisions.
