A new fMRI study shows that when people are exposed to the idea of unequal healthcare funding, a region of the brain associated with social and moral disgust is strongly activated. The study, which is the first to use fMRI scans to observe what happens in the brain when people are asked to make difficult choices on healthcare spending, found that the anterior insula was activated when people felt an unfair choice had been proposed. The anterior insula is involved in processing human disgust — such as the experience of foul smells or unpleasant images — but is also triggered when we feel a strong sense of moral outrage — for example, at the perceived breach of social or ethical norms.
