Can’t read the study because paywall but is there anything about factors/questions beyond not knowing how to flirt and being choosy? I get that people who are single might feel like they can’t flirt but that doesn’t mean people in relationships are actually any better (or better enough for it to be the “main reason”). It could be people in relationships overestimate their skills in comparison to single people. I feel like this headline is bullshit. Main reason for single people is they can’t flirt - idk if I believe it. There are way too many factors with modern dating for me to really believe it. Instead, this reads like - “of the very limited set of questions we asked, flirting was the reason” but that’s not the headline.
