DISC assessment

A DISC assessment is a pseudoscientific personality testing tool based on psychologist William Moulton Marston's DISC emotional and behavioural theory, first published in 1928. These assessments claim to improve job performance by categorizing individuals into four personality traits: dominance, inducement, submission, and compliance.

The scientific validity of the DISC assessment has not been demonstrated, and psychologists question its predictive validity. Despite this, the DISC assessment remains widely used in business, coaching and organizational development.
