Meanwhile, psychologists have proven that these practical reasons have nothing to do with "evolutionary survival".
Experts at the University of California found that people recognize "beauty" based on the ease of processing visual information. The easier it is for the eye to absorb the person’s facial features, the more "beautiful" the face is thought to be. The ultimate in "perfect" looks is simply our brain's ability to process visual data with as little effort as possible.
Even more subjective is the popular appeal of facial features, which is connected to the absolute commonality of a stereotype. In plain language, beautiful people are those who most closely resemble what the majority of us imagine to be "us". At least that's the finding of American psychologists.
