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.
Men and women are rotated to meet each other over a series of short "dates" usually lasting from three to eight minutes depending on the organization running the event.
At the end of the event participants submit to the organizers a list of who they would like to provide their contact information to.
If there is a match, contact information is forwarded to both parties.
Requirement for each event vary with the organizer.
Specific age range based on gender is a common restriction for events.
Speed Dating, as a single word, is a registered trademark of Aish Ha Torah.
Speed dating, as two separate words, is often used as a generic term for similar events.
On the other hand, feedback and gratification are delayed as participants must wait a day or two for their results to come in.
The time limit ensures that a participant will not be stuck with a boorish match for very long, and prevents participants from monopolizing one another's time.
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.
