Mating game: Too much choice will leave you lonely

From PhysOrg:

British investigators, in a new study released on Wednesday, looked at the strange dynamics of choice in speed-dating, a fashionable way for singles to meet. Speed-daters race through a rota of one-on-one meetings, judging each person for suitability after a conversation of a few minutes that ends when a bell sounds. Assessing large numbers of candidates was not a problem in itself, the researchers found. In fact, many speed-daters found more potential partners when they were able to cast their net into a larger pool. But this advantage only worked when the available candidates were all broadly similar. When candidates were too dissimilar, speed-daters became confused by many conflicting factors — and often failed to choose anyone. “There are models of human 'rationality' which posit that variety is a good thing,” said researcher Alison Lenton at the University of Edinburgh in Scotland. “What will be surprising to some people is that our results suggest that increasing option variety leads to chooser confusion. People are more likely to choose no-one at all when faced with greater variety.”

The study, published in the British journal Biology Letters, tracked 1,868 female and 1,870 male participants at 84 commercial speed-dating events. Hopeful singles gave details of their occupation, education level, age, height, weight and religious affiliation, allowing researchers to gauge differences. The women's mean age was 34.3 years and men were aged 35.6. Twenty percent of women and 27 percent of men were in professional or managerial positions, and the remainder classified themselves as “skilled non-manual” or other occupations. Speed-daters met in groups and engaged in three-minute encounters with between 15 and 31 singles of the opposite sex. After the event, the organiser matched up individuals who indicated a mutual interest in each other, thus opening the way to a possible date. Big speed-dating events typically generated 123 such “proposals,” or shows of interest, when candidates were similar, the researchers found. But the number dropped by more than a quarter, to 88, when candidates were varied. Small speed-dating events would lead to 85 proposals when candidates were similar. But this fell by nearly a third, to 57 proposals, when candidates were varied. Men were generally keener than women in formulating a proposal — but were also likelier to be stumped by choice.

In short, variety is fine… but in manageable doses.
