Netflix hired cultural anthropologist Grant McCracken to examine our national attitude towards spoilers, and found that more than 75 percent of us weren’t really bothered by finding out unwanted info about our favorite television shows. That’s probably because everyone is doing it — so much so that McCracken categorized five different types of TV spoilers. Most disconcerting is the Power Spoiler, who ruins television shows as a way of demonstrating his or her high social value. As McCracken put it, “To know about a show that you don’t know about is to have power. I live in the future that you are about to occupy.” To avoid this type of spoiler, never talk television with a guy who looks like this.
