The Science of Going Viral

facebook share

Just one in every 20 Facebook photos is shared. Most Twitter hashtags vanish into oblivion. Researchers want to understand the exceptions. Can you predict what content will go viral? That could be handy in many contexts—marketing, elections, revolutions.

This week two new papers are proclaiming advances in the science of virality.

“We have a method that allows us to predict the future on Twitter,” says James H. Fowler, a professor of medical genetics and political science at University of C…

What’s Driving Human Evolution Now?

Last year, when Sir David Attenborough, the British naturalist and broadcaster, speculated that human beings had ended natural selection through cultural and technological innovations, he got a deserved amount of blowback. The criticism started with his toy-model view of evolution, and went from there. But beneath it all, there was one lingering…

The Evolution of Aww

We live in the golden age of cute. As one scholar recently put it, cuteness has become a “dominant aesthetic category in digital culture.” Hard to argue with that. Even if you steer clear of toddler pics on Facebook, even if you’ve never clicked on Reddit’s popular “aww” category, your elderly former neighbor will still email you a random photo of, say, three adorable piglets peeking out of a coffee mug.

That last one may be specific to me, but…

Here Come the Neurothugs! Run!

One of Francis Bacon's self portraits

In this New Atlantis essay about art and science, Roger Scruton coins a word: neurothugs.

Neurothugs are researchers who believe that, when it comes to beauty, there is “such a thing as the fMRI of the beholder, and this does contain the secret of the image in the frame.”

As thugs go, the neuro-variety are among the least threatening. At most they might try to convince you that a brain scan means more than it does. They probably won’t rough you up in an alley.

Scruton, a visiting professor of p…

The Sweet Kisses of Embodied Cognition

Best lollipops
I wandered into a session on embodied cognition at last week’s Society for Personality and Social Psychology conference, and I walked away thinking what I heard can’t possibly be true.

I mean, it just can’t be. Can it?

Research on embodied cognition—the idea, basically, that the body strongly influences the mind in multiple ways we’re not aware of (though not everyone agrees with that definition)—is a fairly new field, and in the last few years it has produced a number of head-scratching resu…

Gaming vs. God

Whether violent video games make you more aggressive has been much debated. Much less discussed is whether video games make you an atheist.

OK, not make you an atheist—that’s too strong. But a new study in the International Journal for the Psychology of Religion does find that playing video games reduces a sense of the numinous, i.e., the feeling that there is a force out there beyond ourselves and the physical world.

In the study, two Canadian researchers first had 56 undergraduates ta…

Wait, So Does Meditation Actually Work or Not?

Depending on which news account you read, a recently published meta-analysis of meditation studies either confirmed the therapeutic value of the practice or proved that it’s not so great after all. For example, Time reported that the studies reviewed showed we need to take meditation “more seriously as medicine,” while an Australian news site emphasized that meditation “lacked evidence of leading to better health.”

So should we all assume the lotus position or what?

First, some context. The an…

Joseph Hill, an assistant professor at the University of North Carolina at Greensboro, believes he is the only black, deaf, Ph.D. linguist in America, and maybe in the world. “Just me,” he told an audience of about 40 people on Sunday at the Linguistic Society …

Does Familiarity Breed Contempt or Fondness?

Two Male FriendsYou meet someone new. You have lunch, maybe see a movie. Along the way you discover things about the other person. It’s not as if you’re keeping a list of this person’s habits and traits—that would be weird—but you’re accumulating information nonetheless.

So here’s the question: As you get to know each other, will you generally like this other person more or less?

Assuming that you don’t discover something unexpectedly awful, like a fondness for hurling bricks at squirrels, the answer is proba…

A Victory for Psychological Research

Researchers are encouraged by newly released results of a project that successfully replicated 10 of 13 psychological studies. The project, conducted by a large international consortium, was set up in response to findings in recent years that many psychological studies, including classic experiments, were flawed.


Ten of the effects were consistently replicated across different samples. These included classic results from economics Nobel laureate and psychologist Daniel Kahneman at Princeton University in New Jersey, such as gain-versus-loss framing, in which people are more prepared to take risks to avoid losses, rather than make gains. . . .
Of the 13 effects under scrutiny in the latest investigation, one was only weakly supported, and two were not replicated at all. Both irreproducible effects involved social priming.
