“…This subcortical region has been demonstrated to be involved in a wide range of psychological processes, such as outgroup discrimination [ 55 ], political inclinations [ 56 , 57 ] and even social network size [ 58 ]. Though seemingly disparate constructs, these processes interact as socially relevant facets of any large society [ 59 ], and the evidence surmounting the recurring relevance of the amygdala suggests an overarching social process governed by this region. In fact, research in how amygdala volume correlates with scores in the system justification scale points to its important role in the maintenance of hierarchical social systems [ 60 ].…”

Neuroanatomical correlates of system-justifying ideologies: a pre-registered voxel-based morphometry study on right-wing authoritarianism and social dominance orientation

System-justifying ideologies are a cluster of ideals that perpetuate a hierarchical social system despite being fraught with inequalities. Right-wing authoritarianism (RWA) and social dominance orientation (SDO) are two ideologies that have received much attention in the literature separately and together. Given that these ideologies are considered to be stable individual differences that are likely to have an evolutionary basis, there has yet to be any examination for volumetric brain structures associated with these variables. Here, we proposed an investigation of overlapping and non-overlapping brain regions associated with RWA and SDO in a sample recruited in Singapore. Indeed, it will be interesting to determine how RWA and SDO correlate in a country that proactively promotes institutionalized multi-culturalism such as Singapore. RWA and SDO scores were collected via self-report measures from healthy individuals (39 males and 43 females; age 25.89 ± 5.68 years). Consequently, voxel-based morphometry (VBM) whole brain and region of interest (ROI) analyses were employed to identify neuroanatomical correlates of these system-justifying ideologies. RWA and SDO scores were strongly correlated despite the low ideological contrast in Singapore's sociopolitical context. The whole brain analysis did not reveal any significant clusters associated with either RWA or SDO. The ROI analyses revealed clusters in the bilateral amygdala and ventromedial prefrontal cortex (vmPFC) that were associated with both RWA and SDO scores, whereas two clusters in the left anterior insula were negatively associated with only SDO scores. The study corroborates the claim of RWA and SDO as stable individual differences with identifiable neuroanatomical correlates, but our exploratory analysis suggests evidence that precludes any definitive conclusion based on the present evidence.

Political Choice in a Polarized America

What motivates citizens to support one party over the other? Do they carefully weigh all the relevant issues and assess which party or candidate best matches their own positions? Or do people look at politics as something more akin to a team sport—the specifics do not matter as long as you know what side your team is on? Understanding how and why Americans vote the way they do is central to understanding the political process. Political Choice in a Polarized America claims that individuals have core beliefs about what the government should or should not do, and these attitudes explain a great deal about what party a person identifies with and votes for. Moreover, the book demonstrates these attitudes’ explanatory power has increased in recent decades. Its thesis rests on the idea that voters generally try to support the party or candidate that best matches their orientations. However, voters’ ability to successfully do so varies as a function of the signals sent by elites. Voters have an easier time connecting their own orientations with the party offerings when the parties are polarized. As a result, voters’ policy attitudes explain a lot more about their partisan preferences than they did in previous eras. When the parties are polarized, people notice, even if they do not place close attention to politics. The result is an electorate divided by partisanship, policy, and ideology.
