There are two primary philosophical approaches to examining the relationship between human bodies and political bodies. The first, reflected in traditional political theory on the body politic, is concerned with the question of how individuals aggregate into functioning or malfunctioning collectives—how singular citizen bodies come to constitute wider political entities. The second approach, maturing later in 20th century social and political philosophy, considers the opposite relation: instead of evaluating how the body politic emerges from the bottom-up, it focuses on how (...) bodies become politicized from the top-down. This, more sociological, perspective explores how human bodies are disciplined and learn to self-discipline into particular physical forms and functions. Dominant ideologies can infiltrate the bodies of adherents, and the task of the social critic or political philosopher is to delineate how, why, where, and when political structures shape the minds and bodies of citizens, as well as whether the effects are coercive, destructive, or liberatory. I will argue that a political philosophy of mind cannot flourish without attention to the cognitive science of ideologies. Until recently there has been little serious dialogue between biology and political philosophy, partly due to disciplinary balkanization and mostly because of the infancy of empirical biopolitics, the science of how cognitive and neurobiological processes are molded by political ideologies. I will suggest that attending to the emerging science of ideological cognition can allow us to build a stronger, more compelling, and provocative thesis on the mind-shaping consequences of immersion in ideologies than is possible with conceptual tools alone.

Research into the roots of ideological extremism has traditionally focused on the social, economic, and demographic factors that make people vulnerable to adopting hostile attitudes toward outgroups. However, there is insufficient empirical work on individual differences in implicit cognition and information processing styles that amplify an individual’s susceptibility to endorsing violence to protect an ideological cause or group. Here we present original evidence that objectively assessed cognitive inflexibility predicts extremist attitudes, including a willingness to harm others, and sacrifice one’s life (...) for the group. Across two samples (N = 1,047) from the United Kingdom and United States, structural equation models demonstrated that cognitive inflexibility predicted endorsement of violence to protect the national ingroup, which in turn predicted a willingness to die for the group. These statistical models accounted for an average of 31.4% of the variance in willingness to die for the group, after accounting for demographic variables. Furthermore, cognitive inflexibility was related to greater confidence in the decision to sacrifice one’s life in an ingroup trolley problem scenario. Analysis of participants’ performance on the cognitive tasks revealed that cognitive rigidity – distinctly from other aspects of cognition – was specifically implicated as a cognitive antecedent of extremist attitudes.
