This is the book "Survival of the Prettiest: The Science of Beauty" by Nancy Etcoff, a cognitive psychologist at Harvard University. This non-fiction book sharply analyzes what we perceive as "beautiful" and why we are attracted to it, drawing on the latest findings from cognitive science and evolutionary psychology. Author: Nancy Etcoff Translator: Hiroe Kimura Publisher: Soushisha Main Theme: Argues that "beauty" is not a culturally constructed myth, but an instinctive response rooted in the survival and reproduction of living beings. Main Content/Topics Based on abundant experimental data, the book covers interesting topics such as: Beauty as Instinct: The standards of beauty are innate, as even infants a few months old gaze longer at faces that adults find beautiful. Signs of Health: Features we find beautiful (skin texture, hair shine, body symmetry, etc.) are indicators of biological health and reproductive capacity. Social Advantages: Cruel yet realistic data is presented showing that beautiful people are favored from childhood and have advantages in job seeking and choosing a spouse. Fashion and Beauty: Explains how cosmetics, trends, and cosmetic surgery are means to emphasize biological signals. This book attempts to unravel the social issue of "beauty privilege" from a scientific perspective, rather than dismissing it as a matter of personal preference.
