this topic inspired me to make a tinder account just to see how "easy" it really was to get laid using online dating. I haven't had sex in 10+ years, and I haven't been on a date in around 5 years.
in the course of about 2 days I have swiped right as much as possible before needing to refresh (takes 12 hours before they give you back more swipes)... basically with any person that I could conceivably see myself having physical contact with under any circumstances. I gave every single person the benefit of the doubt and assumed the best possible things about them based on their profile.
here are my findings:
I got 6 mutual matches in this time period, out of probably 200-300 right swipes. that means I'm getting 2-3% of people who actually match me back. for reference, my reply rate on OK Cupid was around 10%, but I also sent far fewer messages so that was a small sample size and probably contained selection bias.
Just out of curiousity, how old are you and what sort of area do you live in (rural, urban, suburbs, etc)?
