According to a group of Harvard mathematicians, these are the three questions to ask to see if you’re compatible with your partner. 

“Do you like horror movies?”

“Have you ever travelled around another country alone?”

“Wouldn’t it be fun to chuck it all and go live on a sailboat?”

According to the mathematicians — who also happened to create OK Cupid — if you both answer the three questions exactly the same, then you’re a perfect match. 

They came up with the three questions based off a “compatabilty algorithm” they created from the answers to survey questions.
