Now, the Sock Puppet, on the other hand, is a totally different animal. The sock puppet isn't about ambiguity, per se. It's about identity. Let me give you a very recent example, as in, like, last week. Here's R.J. Ellory, best-seller author in Britain. Here's one of his bestselling books. Here's a reviewer online, on Amazon. My favorite, by Nicodemus Jones, is, "Whatever else it might do, it will touch your soul." And of course, you might suspect that Nicodemus Jones is R.J. Ellory. He wrote very, very positive reviews about himself. Surprise, surprise.

Now this Sock Puppet stuff isn't actually that new. Walt Whitman also did this back in the day, before there was Internet technology. Sock Puppet becomes interesting when we get to scale, which is the domain of the Chinese Water Army. Chinese Water Army refers to thousands of people in China that are paid small amounts of money to produce content. It could be reviews. It could be propaganda. The government hires these people, companies hire them, all over the place. In North America, we call this Astroturfing, and Astroturfing is very common now. There's a lot of concerns about it. We see this especially with product reviews, book reviews, everything from hotels to whether that toaster is a good toaster or not.

Now, looking at these three reviews, or these three types of deception, you might think, wow, the Internet is really making us a deceptive species, especially when you think about the Astroturfing, where we can see deception brought up to scale. But actually, what I've been finding is very different from that. Now, let's put aside the online anonymous sex chatrooms, which I'm sure none of you have been in. I can assure you there's deception there. And let's put aside the Nigerian prince who's emailed you about getting the 43 million out of the country. (Laughter) Let's forget about that guy, too. Let's focus on the conversations between our friends and our family and our coworkers and our loved ones. Those are the conversations that really matter. What does technology do to deception with those folks? All right, well, what about online dating? I mean, that's a pretty deceptive space. I'm sure you all have "friends" that have used online dating. (Laughter) And they would tell you about that guy that had no hair when he came, or the woman that didn't look at all like her photo. Well, we were really interested in it, and so what we did is we brought people, online daters, into the lab, and then we measured them. We got their height up against the wall, we put them on a scale, got their weight -- ladies loved that -- and then we actually got their driver's license to get their age. And what we found was very, very interesting. Here's an example of the men and the height. Along the bottom is how tall they said they were in their profile. Along the y-axis, the vertical axis, is how tall they actually were. That diagonal line is the truth line. If their dot's on it, they were telling exactly the truth. Now, as you see, most of the little dots are below the line. What it means is all the guys were lying about their height. In fact, they lied about their height about nine tenths of an inch, what we say in the lab as "strong rounding up." (Laughter) You get to 5'8" and one tenth, and boom! 5'9". But what's really important here is, look at all those dots. They are clustering pretty close to the truth. What we found was 80 percent of our participants did indeed lie on one of those dimensions, but they always lied by a little bit. One of the reasons is pretty simple. If you go to a date, a coffee date, and you're completely different than what you said, game over. Right? So people lied frequently, but they lied subtly, not too much. They were constrained
