The maths of modern dating πŸ’˜

It’s not for everyone, but we can’t deny that online dating has lead to the start of a significant number of relationships in the past couple of decades. Some of these likely ended after a few months, but for some, online dating allowed them to find the love of their life for which I’m sure they will be forever grateful πŸ‘©β€β€οΈβ€πŸ’‹β€πŸ‘¨…and you guessed it, it’s all down to mathsπŸ‘ŒπŸ»πŸŽ‰

Dating websites find your matches using a set of rules (an algorithm). For the site OK Cupid πŸ’˜, this algorithm is based on answers to multiple choice questions. As a user, you answer as many multiple choice questions as you like, as well as giving the answer you would like your potential date to choose and a measure of the importance of that question in your eyes πŸ‘€ (is it a deal breaker if they leave the toilet seat up? 🚽❌)

Your potential date is then given a score based on their answers to the same questions, weighted by the importance of those questions in your eyes (you also receive a score weighted by their views on each question importance).

Finally, a match score is decided by multiplying each of your scores together and then taking the nth root where n is the number of questions you answered in common. The higher this match percentage is with someone, the more likely you will show up in their top results πŸ‘‹πŸ» (and for them to be in yours).

Even tinder has a mathematical method to it’s madness in order to determine who you are more likely to see pop up. For this one, it seems that scores are given based on how many people swiped right to you and these are weighted by other factors such as the swipers likelihood to swipe right etc. You are then more likely to see the people that have a score similar to your own.

So could cracking the maths help you find your one true love? πŸ€·β€β™€οΈβ€οΈ
