My Valentine’s Day themed posts have been both popular and fun to write. In last year’s Getting a Date for Valentine’s Day series, you learned that you should wear something red, gaze without being creepy, tell a good joke before walking up to your potential date who is preferably standing next to some flowers, and then open with a unique request to segue into asking them out. But that isn't the end of the story. Oh no, there are many more things that you can do to attract that special someone, all scientifically examined of course. Today we’ll take a look at two more of them.
It’s serendipity that our V-day themed discussion about sexual selection starts on Darwin’s birthday (Happy Birthday Chuck!). Did you know that Charles Darwin was actually the first to suggest that dance plays a role in evolution? It is a sexually selected courtship signal that reveals the genetic or phenotypic quality of the dancer, usually the male. Basically, the quality of the movement signals things like physical strength and fluctuating asymmetry (FA). The latter is a term you see a lot in these types of studies and it describes how much an organism deviates from bilateral symmetry. Essentially, if you develop all lopsided then it will show in your movement. Take what you know of testosterone, or other steroids. Increase that and you see improved physical strength and athletic ability. Now translate that, and its developmental implications, to dance.
The rise of motion-capture technology has added a very useful tool to this type of study. Rather than going through all of those post-conversion video steps, complex movements like dance can be captured by the computer sensors to be applied to homogeneous human figures. A 2005 study by Brown et al. in Nature did just this to look at the variation in dance quality with genetic and/or phenotypic quality. They motion-captured 183 dancers and selected 40 dance animations based on the composite measures/level of fluctuating asymmetry of the dancer (hmm…I wonder if they could get Andy Serkis to help out). Then they showed these dance animations of symmetrical and asymmetrical individuals to 155 people (themselves characterized for FA) to rate. In both males and females, the results showed that symmetrical individuals were better dancers, with males better than females, but sex didn’t matter within the asymmetrical group. For the raters, generally males liked to watch female dancers rather than male (you’re shocked, I can tell), and females liked symmetrical males. Data also showed that female raters, more than male raters, preferred the dances of symmetrical men, and that symmetrical men prefer symmetrical female dancers more than do less-symmetrical men. If you have ever interacted in any social context ever then you know that beautiful, good dancers liking beautiful, good dancing partners isn’t exactly groundbreaking. But what does this study mean for the hopelessly asymmetrical? Shift your preferences downward to a less symmetrical potential date.
Now the question becomes about the dance itself. Which body movements are the attractive ones? A 2010 study by Neave et al. published in Biology Letters looked at specific movement components within dance to see which one(s) influenced perceived dance quality. Using motion-capture, the created digitally dancing avatars of 19 men for 37 women to rate for dance quality. To quantify specific movements, angles, amplitudes and durations of joint, angular and unidirectional movements were measured. Good dancers were those that had larger and more variable movements with faster bending and twisting movements in their right knee. Weirdly specific, right? Especially that right knee thing. But, considering that most people are right-handed, this might be expected.
So what have we learned? Well, we now know that how you move tells someone a lot about you, regardless of how attractive you are. Maybe a good dance class is in order?

Hey baby, you must be gibberelin, because I'm experiencing some stem elongation.
You've got your eye on someone fabulous. You walk over; lean against the bar and…
What you say next can make or break that first meeting. What do you say? There are several studies out there that look for practical answers to this question. Considering our current dating discussion, we’ll hone in on pickup lines (or chat-up lines), which run the gamut from cute to cringe-worthy. In general, these types of studies ask “What makes a pickup line good?”
To get at this, many categorize them according to a 1986 study by Kleinke et al.:
- Cute-flippant – convey interest with humor that is usually flirtatious or sexual
- “You must be tired, because you’ve been running through my mind all day,” (A line that has actually been used on me. Sigh.)
- “Do you have any raisins? No? Well then, how about a date?”
- “Have you seen any good movies lately?”
- “What do you think of the band?”
- “I saw you across the room and knew I had to meet you. What’s your name?”
- “Can I buy you lunch?”
Okay, so now we have zeroed in on the categories that work best: innocuous and direct. But is there something about the lines themselves that make them successful? A 2006 study by Bale et al. aimed to construct a pencil and paper instrument to index the effectiveness of pickup lines and identify cues as to their effectiveness. To do this, they created 40 vignettes in which a man attempted to start a conversation with a woman including 20 “one-liners” chosen as signals of particular male traits. Then participants were asked to rate the man’s pickup on whether or not a woman would continue the conversation. As with the previous studies, pickup lines involving jokes, empty compliments and sexual references rated poorly. Lines that indicated those evolutionary desirable traits did best: generosity, cultured, and physical fitness.
A 2007 study by Cooper et al. built on the Bale et al. work, looking at the effect of personality on the response to pickup lines. This study proposed that these openers can have two functions: attraction and selection. These functions may allow men to increase their effectiveness by skewing the distribution of women they attract towards a particular personality type. The researchers used the short scale version of the Eysenck Personality Questionnaire Revised (EPQ-r) to measure the personality traits of the participants. They also asked the participants to complete a Dating Partner Preference test which asks them to rate 33 adjectives to show how they felt about the trait in a prospective dating partner. Generally, they found four groups of adjectives that were preferred: good mate, compliment, sex (preferred by males), and humor (preferred by females). Are you sensing a theme yet? They also combined their dataset with Bale et al. to establish the relationships among vignettes to explore the effect of the sex of the participant. Women rated humorous items more favorably and sexually loaded lines less favorably than did men. (Again, you’re shocked, I know.) However, it turned out that men underestimated some things; like when he revealed wealth or proffered help in a way that showed off his character and when he handed over control of the interaction to the woman. On the flip-side, he also overestimated how she responded to showing off his accomplishments, especially if it was laden with innuendo.
Lessons learned from this? Construct your pickup lines carefully. Sure, humor is important but in pickup line form it just makes you look like an idiot. Instead, ask her what she thinks, listen and respond intelligently, and talk about yourself without being a show-off. In short, be a normal person, not a weirdo.
