The Science of Soulmates

As Valentine’s Day approaches, couples are snuggling up and making plans for romantic gestures. That may leave those still seeking a partner wondering when they’ll meet that special someone. But how many someones are there for each of us? Do we each have just one true soulmate, that person who is the ideal fit for all of our interests, values, and personality quirks? And if you’re with someone whom you consider special, how do you know you’ve really found The One? 

The likelihood of finding your soulmate 

While it may be impossible to define a soulmate in testable, scientific terms, we can take a look at some cold, hard math to determine how likely we are to meet one particular destined-to-by-mine person on this planet full of people. In fact, Randall Munroe, former NASA engineer and author of the popular web comic xkcd, has done this for us.

First off, out of the hundred billion or so people that have walked this earth, less than 10 percent are still alive today. If we assume our soulmate could have lived during any time period, then for more than 90 percent of us, our soulmates are already dead. Bummer. And this gets worse, as you can imagine, if we have to factor in future, as-of-yet nonexistent people as potential soulmates.

If we assume our soulmate could have lived during any time period, then for more than 90 percent of us, our soulmates are already dead. Bummer.

So, Munroe instead assumes that your soulmate has to not only be alive but is likely in the same age range as you. (Big assumption; I know). This narrows the candidate list from the Earth’s population of 7.5 billion seekers-of-true-love to a mere 500 million people. 

How many strangers do you notice daily? Let’s generously suggest that this could be something like 15 people every single day. If 10 percent of those people are close enough to your age to be considered soulmate material, then in a lifetime of 80 years you might encounter and lock eyes with 50,000 soulmate candidates. That sounds like a lot! But recall that there are about 500 million people on this Earth that are in the right age range to be your soulmate. If you encounter just 50,000 of them, you've only caught the eye of 0.01 percent. As Munroe explains, that means if you lived 10,000 lifetimes, you would only find your one true soulmate once. 

So should we be looking for our soulmate?
