7 Core Personality Factors: Definitions and Examples

Personality has long captivated the field of psychology, serving as one of its most fascinating and widely applied areas. The roots of experimental psychology and the study of human personality trace back to the late 19th century, when German physiologist and philosopher Wilhelm Wundt laid the groundwork for this burgeoning field¹. The seven core personality factors; Agreeableness, Emotional Stability, Extraversion, Honesty/Humility, Industriousness, Methodicalness, and Openness to Experience; are measured by the Jackson Personality Inventory™-3 (JPI™-3). This model builds on the Five-Factor Model (FFM) that American psychologists Paul Costa and Robert McCrae developed to describe Openness to Experience, Conscientiousness, Extraversion, Agreeableness, and Neuroticism (low Emotional Stability), often summarized as “OCEAN.”²

It also builds on the HEXACO model, which Canadian psychologists Kibeom Lee and Michael C. Ashton introduced by adding Honesty/Humility as a sixth factor.³ The JPI-3 refines this further by dividing Conscientiousness into two distinct dimensions: Industriousness and Methodicalness, because conscientiousness has been described as “the most potent, non-cognitive predictor of workplace performance.”⁴ This is a general-personality, workplace-relevant model; it is a different framework from the seven pathological personality traits used in some clinical diagnostic models. In this blog, SIGMA’s experts delve into the definitions, benefits, and key considerations for each of these seven core personality factors.
