Personality Traits and Political Attitude
The relationship between personality and political preferences is not the simple relation between conservatism and negative personality traits on the one hand and liberalism and positive personality traits on the other hand. Personality is understood as the combination of innate dispositions and personal experiences that guides behavior in a stable and predictive manner. Behavior is also determined by environmental circumstances. In this way it is plausible to presume that personality and politics seem related to each other.
More recent research shed some more light on this relationship. The relationship is not assumed to be strictly causal. It seems likely that the relationship between personality traits and political attitude is in part the expression of the same underlying genetic liability. In the end the relationship between personality and political attitudes seems to be influenced by genetics and environmental circumstances.
Individual differences in both personality traits and political attitudes could be decomposed into genetic and environmental variance components.
From a large Australian study data were obtained from 3254 twin pairs of the same sex and 363 unlikely sex pairs. Information was gathered through mailed survey about socio-political attitudes and personality traits and a wide variety of health-related and sociodemographic measures. Personality traits were measured by the short form of the Revised version of the Eysenck Personality Questionnaire with sub-scales for Extraversion, Psychoticism, Neuroticism and Social Desirability.
From this study several relationships between personality and politics stand out:
Psychoticism is strongly related to conservative positions on Punishment, Religious, and Sex attitudes, whereas Social Desirability is related to liberal positions on the same attitudes.
Psychoticism has to be explained. From Wikipedia: Psychoticism is one of the three traits used by the psychologist Hans Eysenck in his P-E-N model (psychoticism, extraversion and neuroticism) model of personality.
High levels of this trait were believed by Eysenck to be linked to increased vulnerability to psychoses such as schizophrenia. He also believed that blood relatives of psychotics would show high levels of this trait, suggesting a genetic basis to the trait.
Critics of the trait have suggested that the trait is too heterogeneous to be taken as a single trait. Others found psychoticism to be strongly correlated to Conscientiousness and Agreeableness. It is believed by others that agreeableness and conscientiousness (both which represent low levels of psychoticism) need to be distinguished in personality models.
Environmental influences are unique to the individual and shape their personality traits whereas the dimension Social Desirability is mostly influenced by the shared environment. Also genetics influences play an important part in personality dimensions but genes are multifaceted. There is no specific gene the be associated with a personality trait nor a political attitude. The relationship between personality and political attitudes is not simple or uniform. This research has shown that causality nor the single left-right ideology can be assumed to explain the relationship between personality and political attitudes.

Have there been any serious studies done on the ethics of using these papers in the public sphere?
Because I’ve been tempted to use them.

Nice blog Dr. Shock, interesting stuff on here. One of my students sent me here as I’m one of the authors on the paper above. I’ll try to respond to Katharine- do you mean the ethics of reporting the findings and their impact, or the ethics of conducting the studies? So, all studies with human subjects go through a rigorous review panel by persons not related to the study. Informed consent must be obtained from all people and they must understand what they consent to. Ethics in research is a very big deal, so you can rest assured the research is ethical by protection of human subjects guidelines. Now, if you mean has anyone done a study on the impact of studies? Certainly, check Google Scholar- basically all academic knowledge on the planet is there. Now, the last part, being tempted to use them, anything published is fair game for referencing, refutation, etc. Just be sure to quote any direct text, and cite the papers you want to use and get permission from the publisher (not the authors) to copy any figures or place any text in anything you plan to publish or put on line and you should be good to go.
