Science of Speed Dating

Scientific Research – the science of speed dating

There have been several studies of the round-robin dating systems themselves, as well as studies of interpersonal attraction that are relevant to these events. Other studies found speed-dating data useful as a way to observe individual choices among random participants.

First impressions

A 2005 study at the University of Pennsylvania of multiple HurryDate speed dating events found that most people made their choices within the first three seconds of meeting. Furthermore, issues such as religion, previous marriages, and smoking habits were found to play much less of a role than expected.

A 2006 study in Edinburgh, Scotland showed that 45% of the women participants in a speed-dating event and 22% of the men had come to a decision within the first 30 seconds. It also found that dialogue concerning travel resulted in more matches than dialogue about films.

Subconscious preferences

Malcolm Gladwell’s book on split-second decision making, Blink, introduces two professors at Columbia University who run speed-dating events. Drs. Sheena Iyengar and Raymond Fisman found, from having the participants fill out questionnaires, that what people said they wanted in an ideal mate did not match their subconscious preferences. Leil Lowndes’s book on female – male courtship behavior, Undercover Sex Signals,introduces how a woman makes a split second decision by choosing potential mates, based on her first impression of them.

Olfaction and the MHC

A 1995 study at the University of Bern showed that women appear to be attracted to the smell of men who have different MHC profiles from their own, and that oral contraceptives reversed this effect.

The MHC is a region of the human genome involved with immune function. Because parents with more diverse MHC profiles would be expected to produce offspring with stronger immune systems, dissimilar MHC may play a role in sexual selection.

A speed “date” lasting several minutes should be long enough for the MHC hypothesis to come into play, provided the participants are seated close enough together.

Olfaction and pheromones

The TV newsmagazine 20/20 once sent both a male and a female set of twins to a speed dating event. One of each set was wearingpheromones, and the ones wearing pheromones received more matches.

Age and height preference

A 2006 study at the University of Essex and the IZA in Bonn  into the relative effects of preference versus opportunity in mate selection showed, while concluding that opportunity was more important than preference, that a woman’s age is the single most important factor determining demand by men. Although less important than it is to men, age is still a highly significant factor determining demand by women.

The same study found that a man’s height had a significant impact upon his desirability, with a reduction in height causing a decrease in desirability at the rate of 5% per inch.

Selectivity

Studies of speed dating events generally show more selectivity among women than among men. For instance, the Penn study reported that the average man was chosen by 34% of the women and the average woman was chosen by 49% of the men.. New studies suggest that the selectivity is based on which gender is seated and which is rotating. This new study showed that when men were seated and the women rotated, the men were more selective.
