Humans are terrible at monogamy. So why do we want it so badly?

There’s lots of evidence that monogamy is an unnatural system that humans invented. The experts explain in our new Netflix show.

From the time we’re kids, we’re bombarded with fairy tales about finding our one true love. Love songs, rom-coms, and stories across cultures and continents all preach a very similar message: Finding your match, your soul mate, is the key to a fulfilled and happy life.

But here’s the thing: Love and monogamy aren’t the same. And humans are terrible at the latter.

In 2016, more than 2.2 million couples got married in America, but more than 800,000 got divorced. Cheating and breakups cause grief and heartache every day. Yet some historians and evolutionary biologists say monogamy is a relatively new, self-imposed system. Their evidence suggests humans lived without it for more than 250,000 years. And we only started marrying for love in the 1700s.

So if monogamy is so hard, why do most of us, all around the world, make it a central goal of our lives?

Vox tackled this question in the first episode of our new show with Netflix, Explained. We’ll have new episodes every Wednesday, on topics ranging from monogamy to gene editing to the racial wealth gap and more. If you like our videos, then you’ll love this show; it’s our most ambitious video project to date.
