Can you fall in love after taking a quiz? This is Science Today. Psychologist Arthur Aron started studying the science of falling in love nearly 50 years ago as a graduate student at the University of California, Berkeley. Since then, he developed a set of 36 questions that he says can bring a close connection between two strangers.

"We’re confident that this procedure of answering 36 questions that gradually get more and more personal—that both people answer as well of a few other items in there like saying what you have in common, things you like about the other—that when you do these things you’re going to feel closer to the other person."

Aron tested the questions in his lab on two participants who ended up marrying each other six months later. But he says the questions were originally meant for accelerating intimacy rather than romance.

"We know these 36 questions get people closer. That can facilitate falling in love. Certainly if many other things are in place, and this happens, it could be the straw that breaks the camel’s back."
