Before the date stamp events begin , each player answered a questionnaire to appraise what the research worker shout " perceived exposure to disease " ( PVD ) — essentially , how germ- and disease - conscious the person was . ( Sample prompt : " I avoid using public telephone because of the risk that I may catch something from a former drug user . " )
Next , participants either sat down for a 20 - minute conversation with an attractive student , ran a gantlet of 3 - minute velocity date or rated a series of online dating profiles custom - made for the bailiwick . After each see encounter , the singles rated their potential mate ’s attractiveness , " dateability , " and how favorable or retreat they seemed .
