The Big Five Personality Model: A personality assessment model that taps five basic dimensions.

The MBTI may lack strong supporting evidence, but an impressive body of research supports the Big Five Model —that five basic dimensions underlie all others and encompass most of the significant variation in human personality.12 Moreover, test scores of these traits do a very good job of predicting how people behave in a variety of real-life situations.13 These are the Big Five factors:

Extraversion. The extraversion dimension captures our comfort level with relationships. Extraverts tend to be gregarious, assertive, and sociable. Introverts tend to be reserved, timid, and quiet.

Agreeableness. The agreeableness dimension refers to an individual’s propensity to defer to others. Highly agreeable people are cooperative, warm, and trusting. People who score low on agreeableness are cold, disagreeable, and antagonistic.

Conscientiousness. The conscientiousness dimension is a measure of reliability. A highly conscientious person is responsible, organized, dependable, and persistent. Those who score low on this dimension are easily distracted, disorganized, and unreliable.

Emotional stability. The emotional stability dimension—often labeled by its converse, neuroticism—taps a person’s ability to withstand stress. People with positive emotional stability tend to be calm, self-confident, and secure. Those with high negative scores tend to be nervous, anxious, depressed, and insecure.

Openness to experience. The openness to experience dimension addresses range of interests and fascination with novelty. Extremely open people are creative, curious, and artistically sensitive. Those at the other end of the category are conventional and find comfort in the familiar.

The Dark Triad: A constellation of negative personality traits consisting of Machiavellianism, narcissism, and psychopathy.

With the exception of neuroticism, the Big Five traits are what we call socially desirable, meaning we would be glad to score high on them. Researchers have found that three other socially undesirable traits, which we all have in varying degrees, are relevant to organizational behavior: Machiavellianism, narcissism, and psychopathy. Owing to their negative nature, researchers have labeled these three traits the Dark Triad —though, of course, they do not always occur together.
