FORER EFFECT: Believing They’re Talking About You

Article written by María Mulattieri, Consultant at Headway Executive Search

Each person is unique, with individual differences shaped by social context, the nature of our psyche, and the interaction between both factors.

However, in everyday and informal situations—such as reading zodiac signs—we may accept personality descriptions that are often general, vague, and applicable to almost anyone. Are there really only 12 types of people in the world?

How is it possible that, despite being unique—with our own preferences, quirks, flaws, and strengths—we can be so predictable?

Psychologist Bertram R. Forer answered this question with what we now know as the Forer effect. This phenomenon, also known as the Barnum effect, refers to people’s tendency to accept vague, general, and ambiguous descriptions as highly accurate and personally tailored to them (American Psychological Association, n.d.).

In his experiment, Forer demonstrated how his students rated personality descriptions as very accurate even though they were identical for everyone and consisted of general statements taken from horoscopes and similar texts. In the mid-20th century, Forer asked a group of students to complete a personality test and then gave them a description supposedly based on their results. Afterward, the students rated the description with an average score of 4.26 out of 5, indicating that they found it highly accurate.

The revealing moment came when Forer disclosed that everyone had received exactly the same text. The description contained vague and general statements such as:

“You have a great need for other people to like and admire you, and yet you tend to be critical of yourself.”

The conclusion of this experiment showed how people often accept general descriptions as highly accurate, as long as they align with their self-perception.

In the professional world—especially in corporate communication and marketing—the Forer effect explains why ambiguous or general messages can emotionally resonate with a broad audience, even when they lack specific or in-depth content.

Although we all share certain characteristics, these develop or manifest differently in each individual. It is valuable to recognize what we have in common, without losing sight of the individual differences that make us unique.
