The rationalist community has many advantages here - it’s a well-bounded, closely connected group of people who are all interested in experimenting with weird social technology. Our version of the matching checkbox site, https://www.reciprocity.io/, has solved the onboarding problem; most rationalists have accounts, though you’ll need to be Facebook friends to see some of them.

That brings us to the second problem: complicated preferences. There are plenty of stories of someone checking someone on Reciprocity, not getting a mutual match, then asking them in person and they say yes. I’ve written more about this here, but I think the basic problem is that people can either be excited, lukewarm, or hostile towards each other. And a lot of people would be interested in trying a date with someone they’re lukewarm towards as long as that person is excited about them, but they don’t want a date where both of them are lukewarm. And there’s no consistent checkbox behavior that will create all excited-lukewarm relationships but no lukewarm-lukewarm relationships.

Unfortunately, it’s now common knowledge that people will sometimes say yes in person when they haven’t checked you on Reciprocity, which means you’re back to having to decide whether or not to ask your crush on a date. Tragic!
A checkbox/swipe feature like on Reciprocity or Tinder, where if you were too chicken to ask someone out directly, you could click a box saying you liked them, and if they clicked the same box on you, you would match. I’m a little skeptical of these for reasons described here, but maybe you could fix it by having separate “excited to date this person” and “willing to try dating this person if they were excited about dating me” levels of box-tick.

Chris is looking dejected. “Man, I haven’t even made it to engaged-stage-zero yet. I’ve tried everything - Keeper, Reciprocity, Manifold.Love, curtfishing. Do you think I should edit my dating doc?”
