Which dimension is NOT part of the Big Five personality traits?

The Big Five personality traits, also known as the Five Factor Model, include Openness to Experience, Extraversion, Neuroticism, Agreeableness, and Conscientiousness. Each of these traits encapsulates a range of human behaviors and characteristics.

Openness to Experience describes the extent to which a person is open-minded, imaginative, and willing to consider new experiences and ideas. Extraversion reflects a person's sociability, energy, and tendency towards being outgoing and engaging with others. Neuroticism indicates emotional stability, where low neuroticism suggests calmness and stability, while high neuroticism can imply emotional instability and anxiety.

Impulsiveness, while it can be related to certain traits within the Big Five, is not one of the five core dimensions themselves. Instead, it is more closely associated with aspects of traits like Conscientiousness, particularly regarding self-control and discipline, rather than being recognized as a standalone personality dimension in the Big Five framework. Recognizing that impulsiveness does not categorize as a primary trait helps to clarify that it does not form part of the foundational model of personality assessment.
