Data (and book) nerds, this one’s for you. Over at r/dataisbeautiful, one young New York City resident has shared his data after seven months of using online dating apps, and the results may surprise you: He’s had the most luck within the New York Public Library system.

In the chart, we can see that he sent 772 likes across Hinge and Bumble, matching with 26 people on Hinge and 31 on Bumble. These matches led to eight first dates and three sexual encounters, resulting in one ongoing relationship and one situationship, which he’s currently in.

What stands out is the branch at the bottom that just says “NYPL: 3” and “Hooked up: 2,” meaning that of the three people he met at the New York Public Library, he hooked up with two of them, giving him a 66.67 percent success rate at the library.

In response to one inquisitive commenter, OP described the New York Public Library as “the most underrated dating spot in town,” adding that people should “forget Trader Joe’s.”

Further elaborating on his library encounters, he shared, “One of them was a staff member at the reference desk who asked me out after I genuinely sought help to reserve a room.”

Elaborating on his methods, he continued, “The other ones were all about patience, it’s very old-school tbh. If you visit the library regularly, you’ll notice that some people have a consistent schedule. These are the ones. Try to see what they’re reading and do some general research about those topics.

“Because you’re aware of their schedules, you should come across them when you’re both either arriving or leaving, here’s when you briefly comment on the specific book they were reading, like small talk-ish. Then you just leave and don’t carry on the convo. The thing is, now that you’ve talked, you friendly salute them everyday. After a couple more brief comments on the readings, you should feel comfortable enough to introduce yourself. That’s all.”

Basically, play the long game and stalk them a little bit. Commenters were torn after seeing this comment, with a couple asking if OP was Joe Goldberg from the hit Netflix show You, while others compared his advice to that of Dennis Reynolds from It’s Always Sunny in Philadelphia and his D.E.N.N.I.S. system. Others said strategies like this were the norm before the internet and the rise of dating apps.

One particularly wise commenter wrote, “If you’re legitimately interested in just learning more about the topic to talk to them in good faith, then that seems fine. But if you’re doing it to try to convey a shared, mutual understanding/passion for a topic for the sole purpose of getting in their pants and bailing, then it’s definitely creep status IMO.”

In other words, do it by the book.
