Today, many of us are willing to pay an algorithm to find us our perfect mate. Pheramor is a new, Houston-based startup that claims to use DNA to match people. The company looks at "attraction genes" to connect people using a phone app. I don’t think there is any evidence that shows that this kind of DNA matching can lead better relationships. Indeed, this is a great example of a very complex—and culturally mediated—human behavior that can’t be reduced to genetics.
