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.
"We see from the results that children and especially girls have more trust in attractive faces, even though there are no obvious reasons why people with more attractive faces would be more reliable or knowledgeable," Bascandziev says.
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.
