A recent study, published in the journal Frontiers in Psychology, has found that children's perception of a person's trustworthiness is linked to how attractive they think they are.
The study, carried out by Dr Fengling Ma and Dr Fe Xu of Zhejiang Sci-Tech University, and Dr Xiaming Lu of Wenzhou Medical University, China, used two groups of participants - children and adults.
The groups were presented with 200 neutral male faces, and were asked to rate them on attractiveness and trustworthiness.
The researchers found that attractiveness and trustworthiness ratings correlated, and this relationship grew closer the older the people surveyed were.
This adds to a body of research that finds conventionally attractive people are perceived as smarter, more successful and more outgoing than others.
In addition, a study earlier this year by Florida State University found that the attractiveness of your partner can impact your dietary choices and fitness.
Doctoral student Tania Reynolds said:
The results reveal that having a physically attractive husband may have negative consequences for wives, especially if those wives are not particularly attractive.
