Freud vs. Eysenck: Comparing Personality Theories

Introduction to Personality and Its Theories

Psychologists have described personality as a specific way of feeling, thinking, and conducting oneself (McLeod, 2014). Personality is a constantly changing system within the minds of individuals, made up of specific psychological traits that influence their behavior and thinking. It is the combination of behaviors and characteristics that distinguishes one person from another. A person's personality is shaped by genetic and biological factors as well as environmental influences such as upbringing and culture.

Personality theories are broadly divided into two classes. Trait theories hold that personality depends primarily on biological factors, while state theories view upbringing and societal factors as the major determinants of personality. This paper explores two major personality theories: Hans Eysenck's Personality Theory and Sigmund Freud's Psychoanalytic Theory.

Sigmund Freud's Psychoanalytic Theory

Freud's theory of personality holds that our differing personalities arise from the interaction between what Sigmund Freud described as the three basic components of human thinking: the id, the ego, and the superego.

The first and earliest-developed of these components is the id, which is concerned with the immediate satisfaction of basic human urges and desires. It operates on its own, largely uncontrolled by conscious reasoning. The superego deals with moral and social conduct — what is commonly referred to as "conscience." A child's upbringing and learned understanding of right and wrong shapes this conscience. The ego, by contrast, is the most logical and practical part of personality. It is less primitive than the id and is partly controllable by human reasoning. Freud described the ego as the "self" and assigned it the function of balancing the competing demands of the id and the superego in a realistic manner.

Freud held that the id, ego, and superego are in a state of constant conflict, and that the behavior of mature persons is rooted in these childhood psychological battles. He argued that individuals with well-developed egos tend to possess healthy personalities, while those who fail to balance these internal demands may suffer from anxiety, persistent sadness, or harmful behaviors (Boundless, 2016).

Freud's Psychosexual Stages of Development

According to Freud, the nature of conflict among the id, ego, and superego changes over time in accordance with the developmental processes that occur during an individual's growth. He proposed that these internal conflicts unfold through five sequential stages, each focused on a different area of the body: oral, anal, phallic, latency, and genital. Freud called this the psychosexual theory of development, with each stage associated with a specific zone of bodily gratification — what he termed "erogenous zones."

During this process, the developing child faces ongoing conflict between biological urges (the id) and ethical conscience (the superego). A child's capacity to resolve these internal conflicts significantly shapes their future ability to function and behave as an adult. Failure to progress beyond a particular stage may cause the individual to become fixated at that stage, resulting in maladaptive personality traits. Successfully completing all stages, however, allows the child to develop into a psychologically healthy adult (Boundless, 2016).

Eysenck's Trait-Based Personality Theory

Hans Eysenck developed his personality theory on the basis of observable personality features. In publications spanning 1952, 1967, and 1982, he constructed an influential model of personality. By carefully analyzing data from personality questionnaires, he identified three distinct personality dimensions: extraversion, neuroticism, and psychoticism (McLeod, 2014).

In the 1940s, Eysenck worked at the psychiatric department of the Maudsley Hospital in London, where his role involved conducting pre-diagnostic assessments of patients' mental difficulties before they met with a psychiatrist. Drawing on this position, he gathered behavioral questions and administered them to approximately 700 soldiers receiving treatment for various mental ailments at the hospital. He found that the soldiers' responses clustered into patterns, suggesting the existence of identifiable personality features. He labeled these first-order personality features and applied a method called factor analysis — a statistical strategy that breaks down specific behaviors and conduct into distinct groupings called dimensions. From this analysis, Eysenck identified two second-order personality dimensions: Introversion/Extraversion (E) and Neuroticism/Stability (N) (McLeod, 2014).

Eysenck argued that these two dimensions combine to produce a wide range of personality features. Extraverts are typically sociable and seek excitement and novelty; they tend to become bored easily and are characterized as adventurous, optimistic, and sometimes impulsive. Introverts, by contrast, tend to be reserved, thoughtful, and highly self-controlled. They are generally serious, capable of forming close friendships, but less inclined toward positive thinking. Neurotics — those scoring high on emotional instability — are typically anxious and prone to moodiness, highly emotionally expressive, and difficult to console when distressed. Emotionally stable individuals, on the other hand, maintain control over their emotions and exhibit low levels of anxiety or sensitivity. Eysenck also added a third dimension — psychoticism — characterized by traits such as lack of empathy, aggression, social withdrawal, hostility, and impulsivity (McLeod, 2014).
