Genome-wide analyses for personality traits identify six genomic loci and show correlations with psychiatric disorders

Personality is influenced by genetic and environmental factors1 and associated with mental health. However, the underlying genetic determinants are largely unknown. We identified six genetic loci, including five novel loci2,3, significantly associated with personality traits in a meta-analysis of genome-wide association studies (N = 123,132–260,861). Of these genomewide significant loci, extraversion was associated with variants in WSCD2 and near PCDH15, and neuroticism with variants on chromosome 8p23.1 and in L3MBTL2. We performed a principal component analysis to extract major dimensions underlying genetic variations among five personality traits and six psychiatric disorders (N = 5,422–18,759). The first genetic dimension separated personality traits and psychiatric disorders, except that neuroticism and openness to experience were clustered with the disorders. High genetic correlations were found between extraversion and attention-deficit– hyperactivity disorder (ADHD) and between openness and schizophrenia and bipolar disorder. The second genetic dimension was closely aligned with extraversion–introversion and grouped neuroticism with internalizing psychopathology (e.g., depression or anxiety)

As cold as a fish? Relationships between the Dark Triad personality traits and affective experience during the day: A day reconstruction study

The Dark Triad of personality is a cluster of three socially aversive personality traits: Machiavellianism, narcissism and psychopathy. These traits are associated with a selfish, aggressive and exploitative interpersonal strategy. The objective of the current study was to establish relationships between the Dark Triad traits (and their dimensions) and momentary affect. Machiavellianism, grandiose narcissism, vulnerable narcissism and the dimensions of the Triarchic model of psychopathy (namely, boldness, meanness and disinhibition) were examined. We used the Day Reconstruction Method, which is based on reconstructing affective states experienced during the previous day. The final sample consisted of 270 university students providing affective ratings of 3047 diary episodes. Analyses using multilevel modelling showed that only boldness had a positive association with positive affective states and affect balance, and a negative association with negative affective states. Grandiose narcissism and its sub-dimensions had no relationship with momentary affect. The other dark traits were related to negative momentary affect and/or inversely related to positive momentary affect and affect balance. As a whole, our results empirically demonstrated distinctiveness of the Dark Triad traits in their relationship to everyday affective states. These findings are not congruent with the notion that people with the Dark Triad traits, who have a dispositional tendency to manipulate and exploit others, are generally cold and invulnerable to negative feelings. The associations between the Dark Triad and momentary affect were discussed in the contexts of evolutionary and positive psychology, in relation to the role and adaptive value of positive and negative emotions experienced by individuals higher in Machiavellianism, narcissism and psychopathy

Leadership Discourse, Culture, and Corporate Ethics: CEO-speak at News Corporation

We explore the language of leadership of global media mogul Rupert Murdoch in 2010, the year before the phone-hacking scandal in the UK came to public attention. Subsequent public enquiries in the UK exposed unethical conduct by staff of News Corporation, a global corporation whose Chairman and CEO was Rupert Murdoch. We focus on the ethical climate fashioned by ‘A Letter from Rupert Murdoch’ that appeared in the opening pages of the annual report of News Corporation for the year ended 30 June 2010. Plausibly, Murdoch’s discourse in that letter helped condition the inapt, unethical conduct of News Corporation staff. We highlight the cultural and ethical signs that were embedded in Murdoch’s letter and which reflected the company’s tone at the top and ethical values. We identify signs of a perverse leadership thinking that possibly help explain the inappropriate cultural values and ethical behaviours that were revealed subsequently in evidence presented to public inquiries

Basic Emotion Recognition According to Clinical Personality Traits

Disturbances in the ability to recognize emotional faces have been attributed to individuals with specific personality disorders. Considering the importance of the dimensional models of psychopathology, studies involving healthy participants are becoming increasingly relevant in the domain of personality disorders. In this context, our main goal was to assess how clinical personality traits affect the ability to recognize basic emotions in a sample of subclinical participants. Photographs of faces expressing six basic emotions (happiness, sadness, fear, anger, disgust and surprise) were presented to 72 undergraduate students (42 womenM age=23.3yr., SD=3.4), whose dominant personality traits (narcissistic, histrionic and compulsive) were assessed using the Millon Clinical Multiaxial Inventory-III. Data were analyzed using both a whole sample regression approach (relating personality traits with emotion recognition performance) and a group comparison approach (comparing groups of participants with dominant personality - narcissistic, histrionic and compulsive - as well as comparing groups with subclinical symptomatology for anxiety and hypomania). The main results suggested a poor recognition of sadness in narcissistic participants and a higher difficulty for anger recognition in participants with anxiety symptoms. These results are discussed within the theoretical framework suggesting that the difficulties in basic and social emotions recognition have implications in interpersonal interactions experienced in different social contexts.Fundacao para a Ciencia e para a Tecnologia (CBMR project) [UID/BIM/04773/2013]info:eu-repo/semantics/publishedVersio

The Dark Side of Personality: Anti-Sociality Increases Strategic Game Play

We assess the role of anti-social personality traits in explaining heterogeneity in commonly observed social preferences. We identified a personality profile that clearly reflects anti-social personality characteristics, with high positive loadings on Machiavellianism and high negative loadings on empathy, trustworthiness and agreeableness. Anti-sociality predicts decision strategies in a manner that is consistent with its name: significantly lower levels of trust and decreased trustworthiness. To identify the strategic nature of anti-social behavior in changing environments, we assessed the moderating role of personality on investor trust and trustee reciprocity in the presence relative to the absence of the investor’s option to punish. Our results show that only the anti-social personality profile is associated with specific payoff maximizing strategy shifts induced by these environmental changes: when punishment was not available to investors, we observe significantly lower levels of investor trust and trustee reciprocity, while there is a significant increase in both behaviors when punishment was available. These effects were specific for anti-sociality, as no other personality factor was associated with such a strong adjustment of decision strategies in the presence of punishment. These results demonstrate that anti-social personality characteristics are associated with strategic behavioral shifts aimed at maximizing the extraction of resources from their counterparts. The reliability of the strategic effects of anti-social personality during trust, reciprocity and punishment strongly supports the notion that self-projection underlies anti-social decision-making
