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, 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.

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.
Extraversion and introversion are a central trait dimension in human personality theory. The terms 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".
The history of the race and intelligence controversy concerns the historical development of a debate about possible explanations of group differences encountered in the study of race and intelligence. Since the beginning of IQ testing around the time of World War I, there have been observed differences between the average scores of different population groups, and there have been debates over whether this is mainly due to environmental and cultural factors, or mainly due to some as yet undiscovered genetic factor, or whether such a dichotomy between environmental and genetic factors is the appropriate framing of the debate. Today, the scientific consensus is that genetics does not explain differences in IQ test performance between racial groups.

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.
