The dark triad is a psychological theory of personality, first published by Delroy L. Paulhus and Kevin M. Williams in 2002, that describes three notably offensive, but non-pathological personality types: Machiavellianism , sub-clinical narcissism , and sub-clinical psychopathy . Each of these personality types is called dark because each is considered to contain malevolent qualities.
111-567: All three dark triad traits are conceptually distinct although empirical evidence shows them to be overlapping. They are associated with a callous–manipulative interpersonal style. High scores in these traits have been found to statistically increase a person's likelihood to commit crimes, cause social distress, and create severe problems for organizations, especially if they are in leadership positions. They also tend to be less compassionate, agreeable, empathetic, and satisfied with their lives, and less likely to believe they and others are good. However,

The factor vectors define an k {\displaystyle k} -dimensional linear subspace (i.e.
333-445: A "best fit" to the data. In factor analysis, the best fit is defined as the minimum of the mean square error in the off-diagonal residuals of the correlation matrix: This is equivalent to minimizing the off-diagonal components of the error covariance which, in the model equations have expected values of zero. This is to be contrasted with principal component analysis which seeks to minimize the mean square error of all residuals. Before

Similarly, another 2008 study using undergraduate participants found that Caucasians tended to score slightly higher than non-Caucasians on Machiavellianism. When attempting to discern whether there are ethnic differences in psychopathy, researchers have addressed the issue using different measurement instruments (e.g.,
555-531: A body of research that continues to grow in the published literature. Paulhus and Kevin Williams found enough behavioral, personality, and cognitive differences between the traits to suggest that they were distinct constructs; however, they concluded that further research was needed to elucidate how and why they overlap. While some psychologists argue that Machiavellianism seems to be indistinguishable from psychopathy and that scales of Machiavellianism seem to measure
666-841: A cyber attack between each part of the dark triad. Psychopathy correlated with faster speeds of persistence and exploitation; narcissism correlated with faster privilege escalation, persistence, and extraction; and Machiavellianism correlated with stealth. Individuals with higher levels of psychopathy are more likely to engage in cyber bullying, with some correlation to both narcissism and Machiavellianism. Individuals with dark triad traits were also found to be more likely to commit acts of online fraud, with each trait having different impacts on factors. Machiavellianism has impacts on opportunity and motivation; psychopathy has impacts on rationalization; and narcissism has impacts on perceptions of motivation and capabilities. Dark triad characteristics correlate with support for various extremist ideologies. Support for

888-480: A heart attack. Studies in Machiavellianism is a book published in 1970 by Christie and his research partner Florence L. Geis. The book consists of a series of studies into a personality style which is characterized by manipulativeness and callousness. It is the first book on the psychology construct that would be named "Machiavellianism", and was the catalyst of creating an entire field of study around

This follows from the model equation and the independence of the factors and the errors: F p ⋅ ε a = 0 {\displaystyle \mathbf {F} _{p}\cdot {\boldsymbol {\varepsilon }}_{a}=0} . In the above example, the hyperplane is just a 2-dimensional plane defined by

When comparing individuals who take both dark triad and light triad tests, the average person was more likely to exhibit light triad traits. This test is not an inversion of dark triad tests, as Kaufman instead focused on developing characteristics that were conceptually opposite from the dark triad. A reliable measure of
1221-445: A meta-analysis of dark triad and workplace outcomes, Jonason and colleagues (2012) found that each of the dark triad traits were related to manipulation in the workplace, but each via unique mechanisms. Specifically, Machiavellianism was related with the use of excessive charm in manipulation, narcissism was related with the use of physical appearance, and psychopathy was related with physical threats. Jonason and colleagues also found that

Both studies suggest that this trolling may be linked to bullying in both adolescents and adults. A 2021 study found that the dark triad's influence may be mediated by malicious motives, and that there is no strong connection between having these traits and engaging in trolling. Adolescents who score higher in dark triad traits show higher amounts of violent delinquency, specifically with interpersonal violence. Individuals with low self control and dark triad traits showed more overall delinquency, however higher self control lowered

The five factor model of personality has significant relationships with the dark triad combined and with each of the dark triad's traits. The dark triad overall is negatively related to both agreeableness and conscientiousness . More specifically, Machiavellianism captures a suspicious versus trusting view of human nature which

Psychologists have studied how dark triad traits affected individuals in their romantic relationships. In most cases these traits cause people to have shorter-term relationships. The people who tend to be higher in these traits will be in relationship types such as "one-night stand, which

Additionally, those who score higher on the light triad scale are intellectually curious, secure in their attachments to others, and more tolerant to other perspectives.

Christie and his colleagues would then develop a psychometric test consisting of colloquialized statements similar to the general writing style of Machiavelli, naming their personality construct "Machiavellianism". High Machiavellianism scores correlated with an cold, unprincipled nature and

A study found that these three constructs are significantly related to one another and manifest similar nomological networks. Although

Lynn proposes "that there are racial and ethnic differences in psychopathic personality conceptualised as a continuously distributed trait, such that high values of the trait are present in blacks and Native Americans, intermediate values in Hispanics, lower values in whites and the lowest values in East Asians." However this research has been heavily criticized for not distinguishing between psychopathy and other anti-social behaviors, confusing between personality and behavioral concepts of psychopathy and presuming rather than demonstrating genetic or evolutionary causes for supposed disparities.

In 1998, John McHoskey, William Worzel, and Christopher Szyarto provoked a controversy by claiming that narcissism, Machiavellianism, and psychopathy are more or less interchangeable in normal samples. Delroy L. Paulhus and McHoskey debated these perspectives at a subsequent American Psychological Association conference, inspiring

These diagonal elements of the reduced correlation matrix are known as "communalities": Large values of the communalities will indicate that the fitting hyperplane is rather accurately reproducing the correlation matrix. The mean values of the factors must also be constrained to be zero, from which it follows that the mean values of the errors will also be zero. Exploratory factor analysis (EFA)
8658-550: The dimensional realm using self-reported instruments, as with the Levenson Primary and Secondary Psychopathy Scales, The Psychopathic Personality Inventory, and the Self-Report Psychopathy Scale. Other groupings of dark personality traits have been proposed. Several researchers have suggested that sadism should be considered a fourth dark trait. While sadism is highly correlated with the dark triad, researchers have shown that sadism predicts anti-social behavior beyond
8769-435: The example above, if a sample of N = 1000 {\displaystyle N=1000} students participated in the p = 10 {\displaystyle p=10} exams, the i {\displaystyle i} th student's score for the a {\displaystyle a} th exam is given by x a i {\displaystyle x_{ai}} . The purpose of factor analysis
8880-486: The factor vectors will define the same hyperplane, and also be a solution. As a result, in the above example, in which the fitting hyperplane is two dimensional, if we do not know beforehand that the two types of intelligence are uncorrelated, then we cannot interpret the two factors as the two different types of intelligence. Even if they are uncorrelated, we cannot tell which factor corresponds to verbal intelligence and which corresponds to mathematical intelligence, or whether
8991-403: The factors allows for evaluation of relationships between observed variables and unobserved variables. Structural equation modeling approaches can accommodate measurement error and are less restrictive than least-squares estimation . Hypothesized models are tested against actual data, and the analysis would demonstrate loadings of observed variables on the latent variables (factors), as well as
9102-482: The factors are linear combinations of both, without an outside argument. The data vectors z a {\displaystyle \mathbf {z} _{a}} have unit length. The entries of the correlation matrix for the data are given by r a b = z a ⋅ z b {\displaystyle r_{ab}=\mathbf {z} _{a}\cdot \mathbf {z} _{b}} . The correlation matrix can be geometrically interpreted as
9213-454: The factors): The sample data z a i {\displaystyle z_{ai}} will not exactly obey the fundamental equation given above due to sampling errors, inadequacy of the model, etc. The goal of any analysis of the above model is to find the factors F p i {\displaystyle F_{pi}} and loadings ℓ a p {\displaystyle \ell _{ap}} which give
9324-414: The hyperplane. We are free to specify them as both orthogonal and normal ( F p ⋅ F q = δ p q {\displaystyle \mathbf {F} _{p}\cdot \mathbf {F} _{q}=\delta _{pq}} ) with no loss of generality. After a suitable set of factors are found, they may also be arbitrarily rotated within the hyperplane, so that any rotation of
9435-541: The key for life success, and behave accordingly. Individuals who are measured to have a high level of Machiavellianism tend to have low agreeableness and conscientiousness . The original published version of the MACH-IV is the most widely used measure in empirical research. Psychopathy is considered the most malevolent of the dark triad. Individuals who score high on psychopathy show low levels of empathy and high levels of impulsivity and thrill-seeking. With respect to
9546-525: The left is the ( a , b ) {\displaystyle (a,b)} -term of the correlation matrix (a p × p {\displaystyle p\times p} matrix derived as the product of the p × N {\displaystyle p\times N} matrix of standardized observations with its transpose) of the observed data, and its p {\displaystyle p} diagonal elements will be 1 {\displaystyle 1} s. The second term on
9657-631: The light triad traits was developed, and demonstrated that they are not simply the opposite of the dark triad's Big Five and HEXACO model traits. The light triad predicts positive and negative outcomes regarding Agreeableness and Honesty-Humility personality traits, and expands on understanding the dark triad as a useful contrasting analog. Individuals who score high on light triad traits also report higher levels of religiosity , spirituality , life satisfaction , acceptance of others, belief that they and others are good, compassion , empathy , self-esteem, authenticity, sense of self, positive enthusiasm, having
9768-420: The mean square error in the off-diagonal components is to be minimized, and this is accomplished by minimizing it with respect to a set of orthonormal factor vectors. It can be seen that The term on the right is just the covariance of the errors. In the model, the error covariance is stated to be a diagonal matrix and so the above minimization problem will in fact yield a "best fit" to the model: It will yield
9879-495: The measurement instruments, and the age of the participants. One interesting finding related to narcissism—albeit one based on non-representative samples—is that while men continue to score higher than women, it seems that the gender gap has shrunk considerably when comparing cohort data from 1992 and 2006. More specifically, the aforementioned findings indicate that there has been a general increase in levels of narcissism over time among college students of both sexes, but comparatively,
9990-423: The model. Thus, no generality is lost by assuming that the standard deviation of the factors for verbal intelligence is 1 {\displaystyle 1} . Likewise for mathematical intelligence. Moreover, for similar reasons, no generality is lost by assuming the two factors are uncorrelated with each other. In other words: where δ p q {\displaystyle \delta _{pq}}
10101-428: The nearly exact same correlations between the Big Five personality traits, which led one research team to conclude that the results of the study supported McHoskey's claim that Machiavellianism ‘‘is a global measure of Psychopathy in non-institutionalized populations.’’ Even a recent study from 2016 notes that Machiavellianism seems to be indistinguishable from psychopathy and that scales of Machiavellianism seem to measure
10212-633: The negative pole of the honesty–humility factor. Typically, any positive effects from the Dark Triad and low Honesty–Humility occur at the individual level, that is, any benefits are conferred onto the one with the traits (e.g., successful mating, obtainment of leadership positions) and not onto others or society at large. Influenced by the dark triad, Scott Barry Kaufman proposed a light triad of personality traits: humanism , Kantianism , and faith in humanity. High scorers on humanism are more likely to value others' dignity and self worth. High scorers on Kantianism are more likely to see others as people, not as
10323-464: The number of factors that ought to be retained. For instance, the parallel analysis may suggest 5 factors while Velicer's MAP suggests 6, so the researcher may request both 5 and 6-factor solutions and discuss each in terms of their relation to external data and theory. Horn's parallel analysis (PA): A Monte-Carlo based simulation method that compares the observed eigenvalues with those obtained from uncorrelated normal variables. A factor or component
10434-1016: The observations via the factor loading matrix ( L ∈ R p × k {\displaystyle L\in \mathbb {R} ^{p\times k}} ), for a single observation, according to where In matrix notation where observation matrix X ∈ R p × n {\displaystyle X\in \mathbb {R} ^{p\times n}} , loading matrix L ∈ R p × k {\displaystyle L\in \mathbb {R} ^{p\times k}} , factor matrix F ∈ R k × n {\displaystyle F\in \mathbb {R} ^{k\times n}} , error term matrix ε ∈ R p × n {\displaystyle \varepsilon \in \mathbb {R} ^{p\times n}} and mean matrix M ∈ R p × n {\displaystyle \mathrm {M} \in \mathbb {R} ^{p\times n}} whereby
10545-418: The other dark triad traits of Machiavellianism and psychopathy had no correlation with looks. Facial features associated with dark triad traits tend to be rated as less attractive. The most pronounced group difference is in gender: numerous studies have shown that men tend to score higher than women on narcissism, Machiavellianism, and psychopathy, although the magnitude of the difference varies across traits,
10656-426: The personality trait. In the 1960s, Christie and his colleagues were interested in studying those who were skilled in controlling and manipulating others. He theorized that a manipulator would have affective-interpersonal characteristics which would be beneficial to their goals, such as having a lack of empathy, disregard for morality, a lack of mental illness, and an indifference to ideology. While conceptualizing
10767-674: The popular Narcissistic Personality Inventory (NPI) was created by Raskin and Hall in 1979. Since the NPI, several other measures have emerged which attempt to provide self-report alternatives for personality disorder assessment. In addition, new instruments have been developed to study pathological narcissism as opposed to grandiose narcissism, which is what many argue the NPI measures. People who score high on this trait, conceptualized in 1970 by psychologists Richard Christie and Florence Geis, are callous, unprincipled, and are excessively motivated by self-interest. They view interpersonal manipulation as
10878-423: The potential factors plus " error " terms, hence factor analysis can be thought of as a special case of errors-in-variables models . Simply put, the factor loading of a variable quantifies the extent to which the variable is related to a given factor. A common rationale behind factor analytic methods is that the information gained about the interdependencies between observed variables can be used later to reduce
10989-560: The psychopathy construct, there is enough evidence to suggest that they are two separate traits, as Paulhus notes that psychopaths are impulsive and careless, which is opposed to the behavior of High Machs who are calculating and plan for the long term. The dark triad traits have significant theoretical and empirical overlap. All three traits share characteristics such as a lack of empathy, interpersonal hostility, and interpersonal offensiveness. A number of measures have been developed to measure all three dark triad traits simultaneously, such as
11100-422: The psychopathy construct. Because of these issues, researchers have proposed that the dark triad traits be merged into one singular construct. Narcissism has also been viewed as interchangeable with Machiavellianism. Psychopathy and narcissism both have their clinical counterparts recognized by psychiatrists, known as narcissistic personality disorder (or NPD) and antisocial personality disorder (or ASPD). Given
11211-414: The right will be a diagonal matrix with terms less than unity. The first term on the right is the "reduced correlation matrix" and will be equal to the correlation matrix except for its diagonal values which will be less than unity. These diagonal elements of the reduced correlation matrix are called "communalities" (which represent the fraction of the variance in the observed variable that is accounted for by
11322-411: The same traits are also associated with some positive outcomes, such as mental toughness and being more likely to embrace challenges. A factor analysis found that among the big five personality traits , low agreeableness is the strongest correlate of the dark triad, while neuroticism and a lack of conscientiousness were associated with some of the dark triad members. Research indicates that there
11433-444: The sample mean is: and the sample variance is given by: The factor analysis model for this particular sample is then: or, more succinctly: where In matrix notation, we have Observe that by doubling the scale on which "verbal intelligence"—the first component in each column of F {\displaystyle F} —is measured, and simultaneously halving the factor loadings for verbal intelligence makes no difference to
11544-447: The set of variables in a dataset. Factor analysis is commonly used in psychometrics , personality psychology, biology, marketing , product management , operations research , finance , and machine learning . It may help to deal with data sets where there are large numbers of observed variables that are thought to reflect a smaller number of underlying/latent variables. It is one of the most commonly used inter-dependency techniques and
11655-462: The traits at a finer level of detail. These researchers found that while some components of the dark triad are related to a fast life strategy, other components are related to slow reproductive strategies. Studies have suggested that, on average, those who exhibit the dark triad of personality traits have an accelerated mating strategy , reporting more sex partners, more favorable attitudes towards casual sex, lowered standards in their short-term mates,
11766-833: The traits within measures of psychopathy already include Machiavellianism and narcissism. For example, Machiavellianism is featured in most of the Factor 1 traits in the PCL-R, in the "Interpersonal Manipulation" factor within the Hare’s Self-Report Psychopathy Scale-III, and in the "Manipulation" scale in the Elemental Psychopathy Assessment. Narcissism is featured within the Psychopathy Checklist as "Grandiose sense of self worth". Machiavellianism and psychopathy also share
11877-434: The two factor vectors. The projection of the data vectors onto the hyperplane is given by and the errors are vectors from that projected point to the data point and are perpendicular to the hyperplane. The goal of factor analysis is to find a hyperplane which is a "best fit" to the data in some sense, so it doesn't matter how the factor vectors which define this hyperplane are chosen, as long as they are independent and lie in
11988-465: The two kinds of intelligence of each student must be inferred from the data. In the following, matrices will be indicated by indexed variables. "Subject" indices will be indicated using letters a {\displaystyle a} , b {\displaystyle b} and c {\displaystyle c} , with values running from 1 {\displaystyle 1} to p {\displaystyle p} which
12099-457: The two types of intelligence are uncorrelated, then we cannot interpret the two factors as the two different types of intelligence. Even if they are uncorrelated, we cannot tell which factor corresponds to verbal intelligence and which corresponds to mathematical intelligence without an outside argument. The values of the loadings L {\displaystyle L} , the averages μ {\displaystyle \mu } , and
12210-525: The vulnerable dark triad members are related to negative emotionality and antagonistic interpersonal styles, they are also related to introversion and disinhibition . According to both research and theory, persons who are highly affected by the Dark Triad are influenced by external, controllable factors. On the contrary, those who are high in the Vulnerable Dark Triad (VDT) are driven by internal, embedded desires. Researchers who criticize
12321-420: Was influential in studies of the authoritarian personality , and in creating the machiavellianism scale in his career. Christie was married to Delores Kreisman, an associate clinical professor of psychiatry, and had five children: a son named Lance, and three daughters, Rebecca, Gail, and Margaret Kellogg. He also had five grandchildren, and three great-grandchildren. Christie died in his apartment in 1992 of
