The social aspects of illness: Children's and parents' explanations of the relation between social categories and illness in a predominantly white U.S. sample.

The COVID-19 pandemic in the United States has had a disproportionate impact on Black, low-income, and elderly individuals. We recruited 175 predominantly white children ages 5-12 and their parents (N = 112) and asked which of two individuals (differing in age, gender, race, social class, or personality) was more likely to get sick with either COVID-19 or the common cold and why. Children and parents reported that older adults were more likely to get sick than younger adults, but reported few differences based on gender, race, social class, or personality. Children predominantly used behavioral explanations, but older children used more biological and structural explanations. Thus, children have some understanding of health disparities, and their understanding increases with age.

What makes Voldemort tick? Children's and adults' reasoning about the nature of villains.

How do children make sense of antisocial acts committed by evil-doers? We addressed this question in three studies with 434 children (4-12 years) and 277 adults, focused on participants' judgments of both familiar and novel fictional villains and heroes. Study 1 established that children viewed villains' actions and emotions as overwhelmingly negative, suggesting that children's well-documented positivity bias does not prevent their appreciation of extreme forms of villainy. Studies 2 and 3 assessed children's and adults' beliefs regarding heroes' and villains' moral character and true selves, using an array of converging evidence, including: how a character felt inside, whether a character's actions reflected their true self, whether a character's true self could change over time, and how an omniscient machine would judge a character's true self. Across these measures, both children and adults consistently evaluated villains' true selves to be more negative than heroes'. Importantly, at the same time, we also detected an asymmetry in the judgments, wherein villains were more likely than heroes to have a true self that differed from their outward behavior. More specifically, across the ages studied participants more often reported that villains were inwardly good, than that heroes were inwardly bad. Implications, limitations, and directions for future research are discussed in light of our expanding understanding of the development of true self beliefs.
