Like it or not, overwhelming evidence suggests that people judge others based on appearances. Although the maxims “Beauty is only skin deep” and “Beauty is in the eye of the beholder” often are used, beauty is an adaptive mechanism for the promotion and evolutionary advancement of the human species. This phenomenon is evident even among babies and young children—studies have shown that they invariably prefer attractive facial features.1
Beauty and the best
The first impression that is created by an individual is highly dependent on physical appearance, and it results in a response that affects how they are perceived and treated. Modern research suggests that people respond favorably to attractiveness and associate it with positive character traits.2 Good-looking people are considered more socially competent, potent and intellectually capable than those who are less attractive. In contrast, abnormal facial features and unattractiveness elicit negative responses and are associated with off-putting personality traits.
Certain physical features often are deemed desirable in all cultures. These include symmetry, youthfulness and averageness. Evolutionary biologists assert that certain facial features are physical indicators of health. These lead to a selective advantage for mating and the advancement of the species, and those who possess them are expected to be more evolutionarily fit and, therefore, more likely to manage the forces of natural selection—resulting in survival. This claim is supported by studies of animals whose symmetry and average features were commonly found in the fittest members of the species.3
