WORLD ECONOMIC FORUM - Sep 30 - Machine learning analyzed 3.5 million books to find that adjectives ascribed to women tend to describe physical appearance, whereas words that refer to behavior go to men. "Beautiful" and "sexy" are two of the adjectives most frequently used to describe women. Commonly used descriptors for men include "righteous" and "rational" and "courageous." The words used for women refer much more to their appearances than the words used to describe men. Positive and neutral adjectives relating to the body and appearance occur approximately twice as often in descriptions of female figures, while male ones are most frequently described using adjectives that refer to their behavior and personal qualities.
