Base-Rate heuristic. The process that involves using common mental shortcuts that help a decision to be made based on known probabilities. For example, if an animal is heard howling in a large city, it is usually assumed to be a dog because the probability that a wolf is in a large city is very low. [25] Peak-and-end heuristic. When past ...
Behavioral confirmation is a type of self-fulfilling prophecy whereby people's social expectations lead them to behave in ways that cause others to confirm their expectations. [1] The phenomenon of belief creating reality is known by several names in literature: self-fulfilling prophecy, expectancy confirmation, and behavioral confirmation ...
Confirmation bias is the tendency to search for, interpret, focus on and remember information in a way that confirms one's preconceptions. [32] There are multiple other cognitive biases which involve or are types of confirmation bias: Backfire effect, a tendency to react to disconfirming evidence by strengthening one's previous beliefs. [33]
Confirmation bias can play a key role in the propagation of mass delusions. Witch trials are frequently cited as an example. [129] [130] For another example, in the Seattle windshield pitting epidemic, there seemed to be a "pitting epidemic" in which windshields were damaged due to an unknown cause. As news of the apparent wave of damage spread ...
The representativeness heuristic is seen when people use categories, for example when deciding whether or not a person is a criminal. An individual thing has a high representativeness for a category if it is very similar to a prototype of that category.
Confirmation bias is the tendency to search for, interpret, favor, and recall information in a way that confirms one's beliefs or hypotheses while giving disproportionately less attention to information that contradicts it. [34] The effect is stronger for emotionally charged issues and for deeply entrenched beliefs. People also tend to ...
Wason attributed this failure of subjects to an inability to consider alternative hypotheses, which is the root of the congruence bias. Jonathan Baron explains that subjects could be said to be using a "congruence heuristic", wherein a hypothesis is tested only by thinking of results that would be found if that hypothesis is true.
The representativeness heuristic is simply described as assessing similarity of objects and organizing them based around the category prototype (e.g., like goes with like, and causes and effects should resemble each other). [2] This heuristic is used because it is an easy computation. [4]
