Almost 100 million people around the world use dating websites and apps. With so many singles looking for love, how do you find “the one?” The task may seem daunting, but the BBC hopes to make it more manageable with tips based on scientific research.

A recent article[*1] written by Dr. Xand van Tulleken explores the world of online dating through the lens of a scientist. Professor Khalid Khan of Queen Mary University has reviewed dozens of scientific research papers on attraction and dating. His most interesting findings and top pieces of advice include:

  • Dedicate 70% of your profile to writing about yourself and 30% to writing about what you’re looking for in a partner. “Studies have shown that profiles with this balance receive the most replies because people have more confidence to drop you a line,” writes van Tulleken.
  • Women are more attracted to men who demonstrate bravery, courage, and the willingness to take risks than they are to men who show altruism and kindness.
  • Humor is highly attractive, but only if you go about it the right way. Although it’s easier said than done, the best way to make people think you’re funny is to show them, not tell them.
  • Choose a username that starts with a higher letter in the alphabet. “People seem to subconsciously match earlier initials with academic and professional success,” van Tulleken explains.

With your profile optimized, it’s time to decide who you’ll go on a date with. Mathematician Hannah Fry suggests employing the Optimal Stopping Theory[*2] , a method that helps you choose the best option when sifting through many possibilities one after another. According to an algorithm devised by mathematicians, your chances of selecting the best date are highest if you reject the first 37% of potential partners.

“The maths of this is spectacularly complicated, but we've probably evolved to apply a similar kind of principle ourselves,” writes van Tulleken. “Have fun and learn things with roughly the first third of the potential relationships you could ever embark on. Then, when you have a fairly good idea of what's out there and what you're after, settle down with the next best person to come along.”

After a few dates with someone special, science can determine whether it’s love or just like. During an MRI, the brain of a person who’s in love will be activated in a region called the ventral tegmental area - a key part of the brain’s pleasure and reward circuit. At the same time, the scan will reveal a deactivation of the dorsolateral prefrontal cortex, which controls logical reasoning. No wonder we call people “fools in love.”

Of course, feeling the emotion doesn’t guarantee a successful relationship, as Dr. Helen Fisher is quick to note. Science can give you a headstart in finding love but the rest is up to you.
