This study investigates whether children's trust in information sources is influenced by the groomed or ungroomed appearance of an individual and whether age affects this decision-making process. A total of 662 children aged 4–10 from kindergarten, second grade and fourth grade participated. Children viewed photos of identical twins labelled as groomed or ungroomed, then watched videos where these individuals named unfamiliar shapes. Results showed that children across all age groups significantly preferred the groomed individual. Analysis of their explanations revealed that kindergarteners relied more on appearance-based justifications compared with older children. From second grade onward, children increasingly shifted towards accuracy- and skill-based explanations, even without direct evidence of competence. This developmental trend suggests that as children's language and reasoning abilities improve, they begin to provide more epistemic justifications rather than relying on superficial cues. Overall, the findings indicate that appearance strongly affects children's epistemic trust decisions throughout early and middle childhood. The study highlights the importance of educational practices that help children critically evaluate information sources based on reliability and competence rather than external appearance.
