To figure out which seemingly innocuous questions correlate with the most revealing ones, OkCupid looked at its database of millions of answers to the more than 275,000 match questions it asks users answer when they first join the service.

The site flagged the questions that users ranked as the least significant (figuring those would be the least intrusive ones to ask on a first date) and then determined how they correlate with the more soul-searching, personal questions.

The site found that whether someone likes the taste of beer is the best predictor of if he or she will have sex on the first date.

"No matter their gender or orientation, beer-lovers are 60 percent more likely to be OK with sleeping with someone they've just met," OkCupid said in its blog post on the topic.
