Ogi Ogas visits Google to discuss his book "A Billion Wicked Thoughts." What really turns us on? Throughout human history, people haven't been honest—with themselves or with each other. What they say they like is often quite different from what they look for when nobody is watching. But how can we learn the truth? Ogas and co-author Sai Gaddam have studied the secret sexual behavior of more than a hundred million people around the world. Their method? They observed what people do within the anonymity of the Internet. Ogas and Gaddam analyzed a billion web searches, a million websites, millions of personal ads, and tens of thousands of digitized romance novels. Their groundbreaking findings will profoundly alter the way you think about human sexual relationships. Originally published in July of 2011. Visit YouTube.com/TalksAtGoogle to watch the video.
