New research by scientists from Harvard, published in the British Journal of Social Psychology, has revealed that children place more trust on adults who are attractive as opposed to unattractive ones.
Lead researcher, Igor Bascandziev, explained, "When learning about the world, children rely heavily on information provided to them by other people. Previous studies have shown children can be influenced by a range of factors such as whether the adult was correct in the past or if they are familiar to them."
During the study, scientists found that children especially girls, portrayed a preference for an attractive face as compared to an unattractive one.
It could just be that we feel more comfortable with people who look attractive. So, there appears to be a certain bias towards attractive individuals.
