What can you learn from that appealing look of testosterone?

The men featured are young. Most are white. Many have tousled hair, a couple sport grizzly beards, and a few are tattooed. As a rule, the men are good-looking. Their cheekbones would make Derek Zoolander proud, but the models are not sitting for their "Blue Steel" close-ups. They are all posing for their mug shots. They are all under arrest.
Some scientists believe that, like a peacock's tail, more masculine faces signal underlying genetic strength. Presumably, these strong men are better able to get what they want—food, women, status—through aggression. Direct confrontation was historically a winning strategy, triggering coevolution of a psychological makeup that encouraged confrontation. Today we rely on social institutions to resolve conflict, but aggression continues to accompany masculinity.
Genes are famously selfish; evolution acts at the level of the gene, not the group. All things equal, anti-social traits will persist so long as they provide their owners a reproductive advantage. Consider not just the bedroom but also the boardroom [ http://pss.sagepub.com/content/22/12/1478 ], where dominant, masculine physical characteristics are still privileged over merit.
Should voting guides include facial breakdowns so that citizens can recognize their own biases? Perhaps, but the affinity for manly faces is built-in for both sexes, so the theoretical voter’s guide would also have to mention that hostile world leaders might be more likely to capitulate to dominant-faced presidents. A threat delivered by Sly Stallone seems—and probably is—more credible than one from Steve Carrell.
Returning to our rowdy heartthrobs—will the NYPD start profiling based on face-width instead of race? Perhaps the police could station female officers at street corners to frisk approaching hot dudes? Luckily, we will probably avoid this porny dystopia. No scientist would testify on behalf of such a program because biology does not equal destiny. Inclination is not action. Genes are neither a promise of reproductive success nor a guarantor of bad behavior. Masculinity may be carried into the present by genetic inertia, but its merit—like any evolved trait—is mediated by our choices, and by the world around us.
