Does anyone use the sites omegle and chatroulette or others that are similar?

We don't. These days, it's too risky. In fact, there are studies now that show that people who are really unlucky are using these sites to have sex with other people they meet on the web. So there's a real risk here. But what's really risky is the incredibly foolish person who uses these sites just to have sex with as many people as they can.

When did this behavior become OK? How do we know this is not just a case of humans having an in-of-sex behavior and then judging it as normal later? And how does this apply to all of sex? I don't know. But I do know that we need to make sure that we have conversations about OKCupid and other sites that allow us to have this in-of-sex behavior, and that we continue to have safe spaces and other mechanisms to help us reject this behavior.

These conversations are hard. And unfortunately, they're painful. But we can't afford to make these conversations any more painful. We can't afford to make these sites or technologies past which sites we don't think of with extreme suspicion, endangering our health, safety and well-being. So today, I'd like to talk a little about cyberbullying.

A few years ago, the number of kids -- actually, up to 15 percent of children -- that are targeted for bullying at school actually decreased, according to the National Center for Education Statistics. And so we did a study looking at whether peer pressure to be nice actually causes kids to be nicer to bullies. And we found a direct relationship between kids being bullied and being nicer to the bullies. So we said, This suggests that kids are just more likely to be nice if they're told that they're going to get bullied, right?

And so we asked researchers all around the world to come get us and analyze our data. And in particular, we wanted to study their brains. And so we wanted to study their frontal lobes, or the prefrontal cortex and striatum. The researchers did study after study after study after our research was published, analyzing brain waves, examining cortisol, all around the world, to see if these trends were changing. And they were. The kids that were being bullied actually showed a decrease in brain activity during the lunch hour, when they were being picked on. So this actually indicated that kids were thinking, This is not going to happen. These kids aren't going to do this.

So we started to understand that the kids were doing the thinking, but the kids in our data set weren't just thinking about it. They were actually activating their activated frontal lobes and their striatum. So we asked researchers around the world to take part in an experiment where they'd get to study these kids' brains and activate their brains while they watched them. And the experiments went really well. But a problem remained. The kids
