if you use the Internet, you're the subject of hundreds of experiments at any given time, on every site.
That's how websites work." In May 2016, a team of Danish researchers have made publicly available the "Ok Cupid dataset" project, containing (as of May 2016) 2,620 variables describing 68,371 users on Ok Cupid for research purposes (e.g., for psychologists investigating the social psychology of dating).
When answering a question, a user indicates his or her own answer, the answers he or she would accept from partners, and the level of importance he or she places on the question. Ok Cupid describes in detail the algorithm used to calculate match percentages.
Assuming a user is a paid user ("A-List"), the site notifies a user if someone likes that user.
Ok Cupid was initially owned by Humor Rainbow, Inc.
Ok Cupid's founders (Chris Coyne, Christian Rudder, Sam Yagan, and Max Krohn) were students at Harvard University when they gained recognition for their creation of The Spark and, later, Spark Notes.
