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.
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.
On the other hand, a couple that decides they are incompatible early on will have to sit together for the duration of the round.
Most speed dating events match people at random, and participants will meet different "types" that they might not normally talk to in a club.
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.
