In psychology, trait theory is an approach to the study of human personality. Trait theorists are primarily interested in the measurement of traits, which can be defined as habitual patterns of behavior, thought, and emotion. According to this perspective, traits are aspects of personality that are relatively stable over time, differ across individuals, are relatively consistent over situations, and influence behaviour. Traits are in contrast to states, which are more transitory dispositions.
In psychology, schizotypy is a theoretical concept that posits a continuum of personality characteristics and experiences, ranging from normal dissociative, imaginative states to extreme states of mind related to psychosis, especially schizophrenia. The continuum of personality proposed in schizotypy is in contrast to a categorical view of psychosis, wherein psychosis is considered a particular state of mind, which the person either has or does not have.
In psychology, the Eysenck Personality Questionnaire (EPQ) is a questionnaire to assess the personality traits of a person. It was devised by psychologists Hans Jürgen Eysenck and Sybil B. G. Eysenck.

The IQ Controversy, the Media and Public Policy is a book published by Smith College professor emeritus Stanley Rothman and Harvard researcher Mark Snyderman in 1988. Claiming to document liberal bias in media coverage of scientific findings regarding intelligence quotient (IQ), the book builds on a survey of the opinions of hundreds of North American psychologists, sociologists and educationalists conducted by the authors in 1984. The book also includes an analysis of the reporting on intelligence testing by the press and television in the US for the period 1969–1983, as well as an opinion poll of 207 journalists and 86 science editors about IQ testing.
Schizothymia is a temperament related to schizophrenia in a way analogous to cyclothymia's relationship with bipolar disorder. Schizothymia was proposed by Ernst Kretschmer when examining body types of schizophrenic patients. Schizothymia is defined by reduced affect display, a high degree of introversion, limited social cognition, and withdrawing from social relations generally. Nevertheless, individuals with such personality traits may achieve relatively affable social relations and a measure of affectivity situationally. As a kind of temperament, schizothymic personality traits are thought to be innate rather than the result of socialization or a lack thereof.

The Temperament and Character Inventory (TCI) is an inventory for personality traits devised by Cloninger et al. It is closely related to and an outgrowth of the Tridimensional Personality Questionnaire (TPQ), and it has also been related to the dimensions of personality in Zuckerman's alternative five and Eysenck's models and those of the five factor model.
The trait of extraversion and introversion are a central dimension in some human personality theories. The terms introversion and extraversion were introduced into psychology by Carl Jung, though both the popular understanding and current psychological usage are not the same as Jung's original concept. Extraversion tends to be manifested in outgoing, talkative, energetic behavior, whereas introversion is manifested in more reflective and reserved behavior. Jung defined introversion as an "attitude-type characterised by orientation in life through subjective psychic contents", and extraversion as "an attitude-type characterised by concentration of interest on the external object".

In psychologist Hans Eysenck's P–E–N model of personality, psychoticism is a trait which is typified by aggressiveness and interpersonal hostility. In 2010, a paper titled "The nature of the relationship between personality traits and political attitudes" claimed to find a strong positive correlation between conservatism and psychoticism. This error was repeated in subsequent papers by the same authors; however, around 2015, the authors acknowledged the correlation is actually negative rather than positive, and began issuing corrections.
