How Do Psychologists Define Personality?

Psychologists debate whether traits and characteristics are inherited or are the result of the environment. They believe that certain traits are related to human behavior. Moreover, the way a person views the world affects their choices. For example, people who believe in opportunities will take risks more often than others. This is one of the most common theories for personality assessment. But the exact nature of personality traits is still unclear. Read on to learn more.

Psychologists define personality in several ways. The most commonly accepted model of personality traits, the Five-Factor Model, highlights the influence of the unconscious mind on a person’s behavior. This theory is based on several psychological theories, such as the stages of psychosocial development. This theory emphasizes the importance of identifying one’s unique traits and fostering a culture in which these values are valued. In addition to the five main personality traits, the Five-Factor Model has several sub-types that can be considered.

Non-genetic factors

Two factors affect your personality: genetics and environment. While genetics account for most of your personality, you are not entirely dependent on them. In fact, according to one study, heritability of different personality traits varied between 18 and 39%. Your environment plays a much larger role in your personality, with approximately 61% to 82% of its influence. Despite these differences, genetics still account for most of your personality, and you should still consider other factors when making your lifestyle and personal decisions.

Myers-Brigg theory

The Myers-Brigg theory of personality was developed by Isabel Briggs Meyers, a mother-daughter team, in the early 1940s. Their approach is based on Carl Jung’s typology, which states that psychology’s final function is to create a complete person. The Myers-Brigg questionnaire contains four sets of two traits or qualities. The resulting report identifies traits and personality types.

Big 5 theory

The Big Five personality theory has been around for more than a century. Based on research conducted since the mid-19th century, the theory describes the main characteristics of human personality. This structure is derived from a method known as factor analysis. This method uses a questionnaire that assesses people’s responses to questions. The five-factor structure is often not universally accepted and may be based on a much larger number of factors. Proponents of the Big Five personality theory say that there is no other model that consistently replicates its five-factor structure across studies.
