PSYPOST - Jan 1 - Tinder has been described as a "hook-up app" - but new research published in Evolutionary Psychological Science suggests that it is not particularly effective at facilitating one-night stands. Researchers from the Norwegian University of Science and Technology were interested in how differences in motivations for using Tinder were related to sexual encounters. In the study, the researchers surveyed 269 Norwegian university students who were former or current Tinder users. Only 54 participants reported engaging in one-night stands following Tinder use and the majority of them had only experienced this once. 80% did not achieve any sexual encounter thanks to Tinder and 13% achieved only one. Only 3% achieved two sexual encounters and 4% achieved more than two. Using data from their new study, the researchers calculated that it took 57 matches on average for a user to have one meeting with a potential partner.
