No definitive evidence for neuroanatomical correlates of system-justifying ideologies

Recommended by Chris Chambers based on reviews by Bonni Crawford and 1 anonymous reviewer

According to the tenets of system justification theory, system-justifying ideologies are beliefs held by individuals to defend and justify the status quo, even when doing do perpetuates social inequalities (Jost and Hunyady, 2005). Two such well-studied ideologies to emerge from political science and social psychology are social dominance orientation (SDO) – the belief that some social groups are superior to others – and right wing authoritarianism (RWA) – the belief that people should follow conventional traditions and authorities, avoiding rebellious ideas. Although considered to be stable traits that may have a heritable basis, there has been little investigation of the neural correlates of SDO and RWA, and it remains unknown whether they are associated with common or distinct brain systems.

In the current study, Balagtas et al. report a novel investigation of the neuroanatomical correlates of both SDO and RWA in a Chinese Singaporean sample using voxel-based morphometry. Based on previous research, the authors chose to focus especially on relationships between SDO, RWA and the volume of the amygdala, ventromedial prefrontal cortex, and anterior insula.

As predicted, the results showed a reliable positive correlation between measures of RWA and SDO; however, none of the neuroanatomical hypotheses were fully supported. Preregistered whole brain analyses revealed no significant regions associated with either RWA or SDO, while ROI analyses identified overlapping (including the amygdala and ventromedial prefrontal cortex) and non-overlapping regions (including left anterior insula) associated with RWA and SDO. Exploratory robustness checks suggested that the authors' spherical ROI localisation method may have identified clusters that were not within the amygdala or left anterior insula, prompting the need for future replication in a larger sample using more precise, atlas-based analyses.

The Stage 2 manuscript was evaluated over two rounds of in-depth review. Based on detailed responses to the reviewers' comments, the recommender judged that the manuscript met the Stage 2 criteria and awarded a positive recommendation.

Level of bias control achieved: Level 4. At least some of the data/evidence that was used to answer the research question already existed AND was accessible in principle to the authors (e.g. residing in a public database or with a colleague) BUT the authors certified that they had not yet accessed any part of that data/evidence prior to IPA.

What are the neuranatomical correlates of system-justifying ideologies?
