The Forer Effect, also known as the Barnum Effect, is a psychological phenomenon where individuals tend to accept vague and general personality descriptions as highly accurate and applicable to themselves. This effect occurs when people are presented with information that appears to be personalized, even though it is actually general and could apply to anyone. The Forer Effect is a form of subjective validation, where people seek out information that confirms their pre-existing beliefs and feelings. This cognitive bias is commonly seen in horoscopes, personality tests, and fortune-telling. The Forer Effect is named after psychologist Bertram Forer, who conducted a study in 1948 where he gave his students a personality test and then provided each student with a personalized analysis of their results. However, the analysis was actually a collection of vague and general statements that could apply to anyone. Despite this, the students rated the analysis as highly accurate and applicable to themselves. The Forer Effect is closely related to other cognitive biases, such as confirmation bias and the illusion of validity. Confirmation bias is the tendency to seek out information that confirms one's pre-existing beliefs, while the illusion of validity is the belief that subjective judgments are accurate and reliable. These biases can lead people to make decisions based on inaccurate or incomplete information, which can have negative consequences. In order to avoid falling prey to the Forer Effect, it is important to critically evaluate information and seek out objective evidence to support any claims. It is also important to be aware of one's own biases and to actively work to overcome them. By doing so, individuals can make more informed decisions and avoid being misled by vague and general statements.

The Forer effect is a cognitive bias that occurs when people believe something is true, even when it isn’t. It’s a type of logical fallacy that happens when people are presented with what looks like personalized information, even though it’s actually general information that could apply to anyone. For example, a child might be given a personality test and then the results could be interpreted and applied to them, even though it’s a general test that could be given to anyone.
Forer Effect, Cognitive Biases, Logical Fallacies, Personality Test
The Forer Effect is a cognitive bias in which an individual perceives a general statement as being highly accurate to their own personality, despite the statement being applicable to a large population. This phenomenon is commonly seen in the form of horoscopes, where people believe a generic message resonates with their own unique life. It is a form of subjective validation, where someone seeks out information which confirms their pre-existing beliefs and feelings. The Forer Effect is closely related to the Barnum effect which is the tendency for people to accept generalized statements as being accurate. Both of these effects can be seen as logical fallacies, as the individual overlooks the lack of specificity in the statement and ignores the possibility of chance.
