The neurobiology of political ideology: Theories, findings, and future directions

AbstractSocial scientists are increasingly interested in studying the psychological bases of political preferences. Research at the interface of neuroscience and political psychology is uniquely positioned to test theories that link political attitudes to cognitive, affective, perceptual, and motivational processes in the brain. In this article, we review existing theories and evaluate findings from the growing field of political neuroscience with an emphasis on four brain regions that have emerged as important neural substrates of political ideology: the amygdala, the insular cortex, the anterior cingulate cortex, and the prefrontal cortex. We conclude by discussing current methodological and theoretical limitations before setting out an agenda for future research.

Linking primary emotional traits to ideological attitudes and personal value types.

The present study aimed at investigating associations of both ideological attitudes and personal value types with the personality traits derived from the Affective Neuroscience Theory (ANT). For that, data of N = 626 (n = 403 men, n = 220 women, n = 3 identifying as neither a man nor a woman) participants of an online survey in the German language were analyzed. Relations of primary emotional traits derived from the ANT with Right-Wing Authoritarianism (RWA), Social Dominance Orientation (SDO), and personal value types, such as the higher-order value type dimensions "Conservation-Openness to Change" and "Self-Enhancement-Self-Transcendence", were examined by means of correlational analyses and structural equation modeling. Results revealed among others relations between low SEEKING, high ANGER and high RWA. Low CARE and high ANGER were associated with high SDO. Moreover, FEAR was related to the higher-order value type dimension ranging from Conservation to Openness to Change. ANGER was associated with the higher-order value type dimension ranging from Self-Enhancement to Self-Transcendence. The present results do not only expand knowledge on the personality traits associated with ideological attitudes and personal value types. Beyond this, considering the neuroanatomical, functional, and neurochemical correlates of the primary emotional traits SEEKING, ANGER, CARE, and FEAR, the present results may provide a roadmap for forthcoming studies aiming at examining biological correlates of ideological attitudes and personal value types, such as those works in the field of political neuroscience.

Political Ideologies through the Lens of Modern Neuroscience

The article presents the standpoint that naturalistic tendencies in modern science, which are especially expressed in neuroscience, push up social knowledge toward the need to revise its attitudes and norms, which consist in consistent sociocentrism and biophobia, and, hence, a simplified understanding of the phenomenon of “genetic reductionism”. We show that the application of the methods of natural science to social disciplines often marked visible progress and even conceptual breakthroughs in their development. Achievements of modern neuroscience affect a traditional area of social and humanitarian knowledge as political science, which leads to the formation of an independent area of research – political neuroscience. Through the optics of this research, cognitive styles characteristic of individuals and social groups with different value orientations imply the dominance of certain ideological sympathies and antipathies, which attributed to the opposite poles of the ideological scale – liberalism and conservatism. Considerable empirical material allows us to conclude that these ideological positions are exist due to differences in their ontogenetic “foundations”, which allows us to develop I. Kant's ideas about a priorism and transcendentalism in the context of the Kantian research program in contemporary neuroscience. The result of the implementation of this program to the political sphere was the discovery of the genesis of political views, and the demonstration of the peculiarities of their dynamics. They are based on the difference in the activity of certain neural sets, which in their turn are influenced by culture and society, forming an integral system “brain – culture – society”, where each component of which affects other components. Features and changes in the socio-cultural context of the development of an individual or a group of people may have an effect upon the architectonics of the brain and shift, due to its plasticity, of the political views along the scale of ideologies “liberalism – conservatism”. At the same time, carriers of different cognitive styles and, therefore, with a sufficient degree of probability of ideological views, percept the world in which they live in differently, and evaluate its past and possible future in diverse ways.

Computational and neurocognitive approaches to the political brain: key insights and future avenues for political neuroscience

Although the study of political behaviour has been traditionally restricted to the social sciences, new advances in political neuroscience and computational cognitive science highlight that the biological sciences can offer crucial insights into the roots of ideological thought and action. Echoing the dazzling diversity of human ideologies, this theme issue seeks to reflect the multiplicity of theoretical and methodological approaches to understanding the nature of the political brain. Cutting-edge research along three thematic strands is presented, including (i) computational approaches that zoom in on fine-grained mechanisms underlying political behaviour, (ii) neurocognitive perspectives that harness neuroimaging and psychophysiological techniques to study ideological processes, and (iii) behavioural studies and policy-minded analyses of such understandings across cultures and across ideological domains. Synthesizing these findings together, the issue elucidates core questions regarding the nature of uncertainty in political cognition, the mechanisms of social influence and the cognitive structure of ideological beliefs. This offers key directions for future biologically grounded research as well as a guiding map for citizens, psychologists and policymakers traversing the uneven landscape of modern polarization, misinformation, intolerance and dogmatism.This article is part of the theme issue ‘The political brain: neurocognitive and computational mechanisms'.

Is there a T.R.U.M.P. brain? Implications for mental health and world peace

Neuroscientists have begun to investigate whether different political attitudes are associated with specific mind-brain markers. In this article, we build on political neuroscience research to briefly illustrate the structure and function of a Threatening, Reactionary, Unforgiving, Machiavellian, and Partisan (T.R.U.M.P.) mindset. Additionally, we discussed, building on neuroscience and clinical evidence, how to counteract the T.R.U.M.P. mindset.

The "chicken-and-egg" problem in political neuroscience.

A comprehensive review by Hibbing et al. establishes close links between physiological and psychological responses and ideological preferences. However, existing research cannot resolve the "chicken-and-egg problem" in political neuroscience: Which is cause and which is effect? We consider the possibility, which they reject, that general ideological postures, if consistently adopted, could shape psychological and physiological functioning.

Political Neuroscience: The Beginning of a Beautiful Friendship

The emergence of political neuroscience—an interdisciplinary venture involving political science, psychology, and cognitive neuroscience—has piqued the interests of scholars as well as the mass public. In this chapter, we review evidence pertaining to four areas of inquiry that have generated most of the research in political neuroscience to date: (1) racial prejudice and intergroup relations; (2) the existence of partisan bias and motivated political cognition; (3) the nature of left‐right differences in political orientation; and (4) the dimensional structure of political attitudes. Although these topics are well‐known to political psychologists, the application of models and methods from neuroscience has renewed interest in each of them and yielded novel insights. There is reason to believe that many other areas of political psychology await similarly promising renewals and that innovative methods will continue to advance our understanding of the physiological processes involved in political cognition, evaluation, judgment, and behavior. We address limitations, criticisms, and potential pitfalls of existing work—including the “chicken‐and‐egg problem”—and propose an ambitious agenda for the next generation of research in political neuroscience.

Of BOLD Claims and Excessive Fears: A Call for Caution and Patience Regarding Political Neuroscience

Published and informal assessments of the prospects for neuroimaging in political science have tended to range from overexuberant to reflexively dismissive. We seek to present a cautious but fair middle ground in considering this new methodology, primarily from an epistemological perspective. Our examination centers on the relationship between two levels of analysis, focusing on the potential for connection between behavior‐based theories of political psychology and cognition and the neural processes and systems involved in generating behaviors and states of mind. We explore the place of each level of analysis on its own, as well as the potential for the fruitful interaction of the two. This analysis brings together opinions and ideas presented by others in various forums and across multiple disciplines, offers a discussion of the the promises and perils of neuroimaging in its application to social science, as well as some practical thoughts regarding its early‐stage incorporation into political psychology. We argue in favor of proceeding with more substantial incorporation of neuroimaging into political psychology's methodological arsenal, but note that this will initially require both (1) greater acceptance of work more focused on presenting empirical results than on providing dispositive evidence in broader theoretical debates and (2) a commitment on the part of those conducting this research to refrain from overstating the definitiveness of its theoretical implications.

Political ideology as motivated social cognition: Behavioral and neuroscientific evidence

Ideology is a potent motivational force; human beings are capable of committing atrocities (as well as acts of generosity and courage) and sacrificing even their own lives for the sake of abstract belief systems. In this article, we summarize the major tenets of a model of political ideology as motivated social cognition (Jost et al. in Psychol Bull 129:339–375, 2003a, Psychol Bull 129:389–393, 2003b, Person Soc Psychol Bull 33:989–1007, 2007), focusing on epistemic, existential, and relational motives and their implications for left-right (or liberal-conservative) political orientation. We review behavioral evidence indicating that chronically and temporarily activated needs to reduce uncertainty, ambiguity, threat, and disgust are positively associated with conservatism (or negatively associated with liberalism). Studies from neuroscience and genetics suggest that right- (vs. left-) wing orientation is associated with greater neural sensitivity to threat and larger amygdala volume, as well as less sensitivity to response conflict and smaller anterior cingulate volume. These findings and others provide converging evidence for Jost and colleagues’ model of ideology as motivated social cognition and, more broadly, reflect the utility of an integrative political neuroscience approach to understanding the basic cognitive, neural, and motivational processes that give rise to ideological activity.
