Abstract *

<p style="text-align: justify;">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 propose 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 institutionalised multiculturalism such as Singapore. In this registered report, we intend to perform a correlational test between RWA and SDO, and an a priori Voxel-Based Morphometry (VBM) analysis to determine the neuroanatomical correlates of RWA and SDO. This study advances four central hypotheses: (a) RWA and SDO will be strongly correlated despite the low ideological contrast in Singapore’s sociopolitical system (b) volume of the amygdala will be positively associated with both RWA and SDO scores, (c) ventromedial prefrontal cortex (vmPFC) volume will be negatively associated with RWA and (d) insula volume will be negatively associated with SDO. The analysis plan and VBM preprocessing pipeline will be made available online on the OSF. Ultimately, we aim to corroborate the claim of RWA and SDO as stable individual differences by establishing their relation to specific structural areas of the brain.</p>

No need for them to be recommenders of PCI Registered Reports. Please do not suggest reviewers for whom there might be a conflict of interest. Reviewers are not allowed to review preprints written by close colleagues (with whom they have published in the last four years, with whom they have received joint funding in the last four years, or with whom they are currently writing a manuscript, or submitting a grant proposal), or by family members, friends, or anyone for whom bias might affect the nature of the review - see the code of conduct

Opposed reviewers - Suggest up to 5 people not to invite as reviewers. (Optional)
