There are many speed dating events now in the United Kingdom, Canada, and the United States.
Many speed dating events are targeted at particular communities: for example, LGBT people, polyamorists, Some feel that speed dating has some obvious advantages over most other venues for meeting people, such as bars, discotheques, etc.
in that everybody is purportedly there to meet someone, they are grouped into compatible age ranges, it is time-efficient, and the structured interaction eliminates the need to introduce oneself.
A 2005 study at the University of Pennsylvania of multiple Hurry Date 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.
According to the New York Times, participants in speed dating experience an average of 2 in 10 or 3 in 10 matches.
Unlike many bars, a speed dating event will, by necessity, be quiet enough for people to talk comfortably. Participants can come alone without feeling out of place; alternatively it is something that women who like to go out in groups can do together.
Because the matching itself happens after the event, people do not feel pressured to select or reject each other in person.
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.
