BUSINESS INSIDER - June 3 - Seth Stephens-Davidowitz, New York Times writer, former Google data scientist, and author of "Everybody Lies" reveals the common language used on successful first dates. A man can increase his odds of getting a second date if he shows support. If he says things like, "that must be tough," or, "that sounds hard." He can also increase the odds of a second date if he laughs at a woman's jokes and doesn't interrupt her constantly. For men, the most beautiful word is "I." When a woman talks about herself more, it's actually a sign that she likes him, she feels comfortable opening up.
