testing Choice quantity and choice variety on dating behavior
—a total of 84 speed dating events
—Rounds of 3 min. dates
—1,868 female & 1,870 male daters
—48 hours to decide on next date (yes-no)
The experiment found and concluded that the ideal number of speed-dating rounds that each participant engaged in was, on average, 23 dates. This is the “sweet spot” because it resulted in more success (more participants wanted to continue dating after each round).
During the experiment, researches checked how variety (i.e. age, height, occupation, education, religion, and smoking habits) affected the participants' dating decisions. When increasing the diversity of daters within the group, the results showed that there were fewer matches between participants or sometimes none at all. There was greater confusion caused by choice overload, rather than by “pickiness” of the participants. This resulted in an overall negative impact on the success rate of the dates.
