VBM findings for personal optimism bias and social optimism bias. Personal bias: A positive correlation between GMV and personal optimism bias arose in areas including the right frontal pole ((x = 20, sagittal) and (y = 57, coronal)), right temporal pole (x = 49, sagittal), left temporal pole (x = −53, sagittal), left hippocampus (x = −33, sagittal), and left putamen (y = −6, sagittal). Social bias: A positive correlation was observed between GMV and social bias in the right temporoparietal junction (x = 64, sagittal) and a negative correlation in right inferior temporal gyrus (x = 54, sagittal). All findings are overlaid on an average template created by normalized anatomical scans across participants. ‘+ve’ stands for positive correlations between GMV and optimism bias (personal/social), and ‘-ve’ stands for negative correlations between GMV and social optimism bias.
