Pareidolia, that’s the reason we love Facebook (and we should not)

Similarly, when we interact with “friends” on social-networking sites or through texting, it can feel like we’re getting quality social contact, but we are not. It turns out that face-to-face interaction with other people—real people, right in front of us, not characters on TV or friends we communicate via text messages—is absolutely vital for longevity and happiness. In fact, it is a larger contributor than exercise or diet!

We need to remind ourselves of our evolutionary history, where we evolved without exposure to realistic representations of people. Back then, if you saw something that looked like a person, by golly it was a person. When you look at a video of a person, most of your brain thinks it’s real—the fusiform face area of your brain area reacts identically whether you’re looking at a real face or a picture of one.
