In a first experiment, the scientists looked at 144 speed dates which were recorded on video.
At the end of each four-minute date, each person decided if they wanted to see the other again.
You also provided ratings on six attributes about your dates: The participants filled out survey questions when they signed up, including what they were looking for in the opposite sex and what they thought others of their own gender looked for. Let's first find out how successful those speed dating events were.
If you take the mean ratings and then subtract the self-rating from the peer rating, you see that participants thought others were more into looks while they were also into sincerity and intelligence. If both you and your partner request another date after the first one, then you have a match.
According to Mc Dermott, earnings for the first quarter of that year amounted to .9 million; profits were .1 million in 2002 versus .7 million in 2001.
“This is a massive business,” said Roben Farzad, a writer for Smart Money magazine in September, 2005
What percentage of initial dates resulted in matches?
In order to make a match, you need to request another date and get that request accepted.
Since the start of the new millennium the online dating industy grew rapidly from year to year. In 2004, however, those high numbers began to drop. Vice President of romance for Match.com, Trish Mc Dermott, reported a 154% growth in revenue, from .3 million in 2001 to 5.2 million in 2002.A 2008 study in which participants rated actual online profiles confirmed this, but also explored the criteria that made certain photos attractive (Fiore et al., 2008).Men were considered more attractive when they looked genuine, extraverted, and feminine, but not overly warm or kind.Their study, published in PNAS, is based on two large field experiments, involving modern dating practices, such as speed dating or partner selection through a dating app.In both cases, the scientists note that the choice of the person, and the success of the encounter were often decided in a very short amount of time.While this has led to dates, relationships and marriages around the globe, it has also been a boon for enterprising researchers — providing huge datasets chronicling real world behavior.
