So you tried loving yourself on the inside but that didn’t work. Now to distract from the inner turmoil, you seek external validation by trying to appear as sexually attractive as possible. Well, you've come to the right place.

Aesthetics 101 reveals what men and women find most sexually attractive in the opposite —based NOT on opinion, but on published empirical data. (Think of it as Cosmo meets Cosmos... or Perez Hilton meets PNAS.)

For my first post, I thought I'd kick it off by answering a question I've tackled in some of my own scientific research: What is the sexiest emotion for men to display?

In two studies using various methods and photographs, my colleague Jessica Tracy and I asked women to rate the sexual of men displaying either pride, , , or neutrality. (Full article can be found here: Tracy & Beall, 2011.) Here’s what we found:

Male Happiness Is Not Very Attractive

Somewhat surprisingly, we found that happiness was consistently rated as the least sexually attractive male emotion expression.

You might think that happiness would be attractive to women because it communicates a man’s friendliness and approachability; smiling tends to elicit trust and approach-oriented behaviors (Becker, Kenrick, Neuberg, Blackwell, & Smith, 2007; Brown, Palameta, & Moore, 2003).

However, when it comes to judging carnal sexual attractiveness, the social communicative messages sent by male happiness could be construed by women as neediness or desperation. Indeed, showing happiness and appearing friendly can be great… If you’re looking for a platonic female friend.

Male Shame Is Pretty Attractive

In our studies, male shame displays were judged as relatively sexually attractive (especially among younger women); male shame was more attractive than male happiness, and not substantially less than male pride.

The shame expression is an appeasement display; it signals that the expresser has violated a social norm—BUT the expresser is also aware of their transgression and feels regret (Gilbert, 2007; Keltner, 1995). Put differently, expressing shame serves as a sincere communication of past mistakes while simultaneously inspiring hope that the expresser is capable of one day changing his ways. Any woman who has ever tried to save a “bad boy” can attest to the romantic appeal of this often misguided plight.

Male Pride Is Very Attractive

In our investigation, we found that pride was consistently rated as the most attractive male emotion expression.

Previous studies have shown that men displaying pride are perceived as higher status than men showing a range of other emotions (e. ., Shariff & Tracy, 2009). So, we essentially confirmed what every 65-year-old male CEO with a Ferrari has known for ages: Women are attracted to high-status men (see Buss, 2008).

In addition to the high-status social communicative message sent by pride, the expanded nature of the pride expression’s physical components may also accentuate men’s musculature and upper-body size—both of which can increase men’s attractiveness to women (Li & Kenrick, 2006).
