The personality test

In psychology, the term "Big Five" refers to a model of personality that groups together five fundamental traits. Introduced by the American psychologist Lewis Goldberg in 1981, then perfected by Costa and McCrae between 1987 and 1992, this model is today an essential reference in personality research. It has contributed to the psychological profiles of millions of people worldwide.

Extensive research has revealed significant links between the dimensions of the Big Five test and various human behaviors, reinforcing its relevance and usefulness in many fields.

Professional performance

Conscientiousness-related performance is positively correlated, regardless of the business sector or evaluation criteria used.

Personality disorders

Each category of the *Diagnostic and Statistical Manual of Mental Disorders* (DSM) is associated with a distinct Big Five profile, generally marked by high levels of neuroticism and low levels of agreeableness.

The Big Five traits are not totally independent of each other, which can lead to partial redundancy when evaluating each category.

In the 2010s, the test associated with the Big Five model was used for military, political and partisan purposes by companies such as SCL Group, via its subsidiaries Cambridge Analytica and Aggregate IQ.

Today, this test is widely adopted and recognized by many companies and industries around the world.
