This week the two most popular words on the Internet are "Gangnam Style." It's fucking everywhere. I typed 'g' into YouTube and it suggested "Gangnam Style." That's how huge it is. I have been hearing about this for a while, but I had not actually seen the video or heard the song. Sometimes I see a meme or some other Internet phenomenon and I say "yeah, I get why that is popular." But then I see something like Gangnam Style, I'm lost. It's a K-pop song that's basically a Korean LFMAO song. And yet it's wildly popular in the United States and elsewhere, in places where the people watching cannot possibly speak a word of Korean. Lots of crappy J-pop and K-pop has been released over the last decade. Why is this super-popular? You can come up with all sorts of reasons why after the fact, but ultimately I'm going to chalk this up to a Taleb moment and just say: there is a reason (because I believe the universe is fundamentally deterministic), but there are too many random factors influencing it for there to be a GOOD reason. FOCUS: What have you encountered that is super-popular or super-influential for totally inexplicable reasons? Do you spend a lot of time trying to figure it out, trying to reassure yourself that the Just-World Hypothesis is really true, or do you just shake your head and move on?
