Watts wanted to find out whether the success of a hot trend was reproducible. For example, we know that Madonna became a breakout star in 1983. But if you rewound the world back to 1982, would Madonna break out again? To find out, Watts built a world populated with real live music fans picking real music, then hit rewind, over and over again. Working with two colleagues, Watts designed an online music-downloading service. They filled it with 48 songs by new, unknown, and unsigned bands. Then they recruited roughly 14,000 people to log in. Some were asked to rank the songs based on their own personal preference, without regard to what other people thought. They were picking songs purely on each song's merit. But the other participants were put into eight groups that had "social influence": Each could see how other members of the group were ranking the songs.Reading through the piece, it seems to me that Watts is primarily concerned with those ideas that don't "break out" and swamp the mainstream -- if you're going to have a modestly successful idea, how can you increase that modest success two- or three-fold? It may be that the combination of a hugely influential person; a simple, easy-to-communicate idea and a receptive market can go viral and be on everyone's lips in a few days. But what if you've got a hard-to-communicate, subtle idea and you want to maximize its spread? Link
Watts predicted that word of mouth would take over. And sure enough, that's what happened. In the merit group, the songs were ranked mostly equitably, with a small handful of songs drifting slightly lower or higher in popularity. But in the social worlds, as participants reacted to one another's opinions, huge waves took shape. A small, elite bunch of songs became enormously popular, rising above the pack, while another cluster fell into relative obscurity.
But here's the thing: In each of the eight social worlds, the top songs--and the bottom ones--were completely different. For example, the song "Lockdown," by 52metro, was the No. 1 song in one world, yet finished 40 out of 48 in another. Nor did there seem to be any compelling correlation between merit and success. In fact, Watts explains, only about half of a song's success seemed to be due to merit. "In general, the 'best' songs never do very badly, and the 'worst' songs never do extremely well, but almost any other result is possible," he says. Why? Because the first band to snag a few thumbs-ups in the social world tended overwhelmingly to get many more. Yet who received those crucial first votes seemed to be mostly a matter of luck.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
