Beards, scars, red clothes, and other secrets of attraction
Hot or not? The question of whom we’re attracted to and why has long confounded humankind’s greatest philosophers, scientists, and reality-show contestants.
Scads of studies suggest that those of us looking for Mr. or Ms. Right may actually be looking for Mr. Facial Symmetry or Ms. Ideal Waist-to-Hip Ratio (about 0.7 for women). [1, 2] But other research suggests that whether a trait is attractive depends on the type of connection you’re looking for. For example, women in one study found men with facial scars more appealing than other men for short-term relationships, but not for long-term ones.  In another study, men with beards had an edge among women seeking long-term relationships—a finding that might give clean-shaven guys with scars an idea about how to turn a one-night stand into something lasting.  (If all of this sounds heteronormative, it is: Almost all research on attraction involves straight people.)
