What is the BarnumEffect?
Thanks forasking. Have you ever felt like your horoscope was written just foryou?
Or a fortune cookie's advice seemed incrediblyrelevant?
You may besurprised, but it's actually not such a coincidence afterall.
This psychological phenomenon is known as the BarnumEffect.
It's a cognitive bias that occurs when people believe that generic personality descriptions and statements apply specifically tothem.
It may explain how practices such asastrology, fortune telling and personality tests have become relatively accepted despite lacking any basis infact.
Ofcourse, people offering such services may not be aware of the Barnum Effectlabel, but many understand how it works and seek to exploit it for theirgain.
Where does the name comefrom?
PT Barnum was an American entertainer and entrepreneur who founded the Barnum Circus in1871.
According to ExplorePsychology.com, Barnum used the formula always have a little something for everybody to explain hissuccess.
But it was only in 1956 that the term Barnum Effect wascoined, with psychologist Paul Meal putting it forward in an essay to express his frustration at patients being told statements that could apply toanyone.
In academicfields, the Barnum Effect is more often referred to as the Forer Effect or subjectivevalidation.
In1948, Bertrand Forer asked his psychology students to complete a personalitytest.
A weeklater, he handed out their personalizedassessments.
In realitythough, there was nothing personalized aboutthem.
Regardless of what they hadanswered, or students received the exact same 13 statements on their personalityvignette.
Theseincluded, you have a great need for other people to like and admireyou.
And while you have some personalityweaknesses, you are generally able to compensate forthem.
So the professor was slacking rather than the students on that occasionthen.
Well,actually, four are proceeded to ask each student to rate how well their assessment could apply to theirpersonality.
On a scale from zero tofive, the result was an average of4.3, meaning for the most part the students saw their vague assessments asaccurate.
Really afterwards did he reveal the real reason behind thetest.
He would go on to publish his findings in the Journal of At Normal and SocialPsychology, under the title The Fallacy of PersonalValidation, a classroom demonstration ofgullibility.
Forer's test was in the interest ofacademia, but unfortunately some people do use the Barnum Effect to trickothers.
