The existing “matching algorithms” miss key variables for long-term love. They necessarily make matches before the parties meet. But studies show that the strongest predictors of solid relationships are a couple’s live interaction style and ability to handle stress. Data about characteristics like personality and attitudes cannot accurately predict how that real life interaction will function.

The scientists also note that online profile photos are poor proxies for the chemistry sparked by meeting in the flesh. Which leads to a lot of disappointing coffee dates. And many potentially successful matches never happen.

Of course the researchers admit online dating helps singles meet more people more quickly. And so might still lead to that magic match. But that’s statistics, not psychology.
