Starting today, PopularScience.com will no longer accept comments on new articles. Here's why.By
It wasn't a decision we made lightly. As the news arm of a 141-year-old science and technology magazine, we are as committed to fostering lively, intellectual debate as we are to spreading the word of science far and wide. The problem is when trolls and spambots overwhelm the former, diminishing our ability to do the latter.
That is not to suggest that we are the only website in the world that attracts vexing commenters. Far from it. Nor is it to suggest that all, or even close to all, of our commenters are shrill, boorish specimens of the lower internet phyla. We have many delightful, thought-provoking commenters.
But even a fractious minority wields enough power to skew a reader's perception of a story, recent research suggests. In one study led by University of Wisconsin-Madison professor Dominique Brossard, 1,183 Americans read a fake blog post on nanotechnology and revealed in survey questions how they felt about the subject (are they wary of the benefits or supportive?). Then, through a randomly assigned condition, they read either epithet- and insult-laden comments ("If you don't see the benefits of using nanotechnology in these kinds of products, you're an idiot" ) or civil comments. The results, as Brossard and coauthor Dietram A. Scheufele wrote in a New York Times op-ed:
Another, similarly designed study found that just firmly worded (but not uncivil) disagreements between commenters impacted readers' perception of science.
If you carry out those results to their logical end--commenters shape public opinion; public opinion shapes public policy; public policy shapes how and whether and what research gets funded--you start to see why we feel compelled to hit the "off" switch.
Even a fractious minority wields enough power to skew a reader's perception of a story.A politically motivated, decades-long war on expertise has eroded the popular consensus on a wide variety of scientifically validated topics. Everything, from evolution to the origins of climate change, is mistakenly up for grabs again. Scientific certainty is just another thing for two people to "debate" on television. And because comments sections tend to be a grotesque reflection of the media culture surrounding them, the cynical work of undermining bedrock scientific doctrine is now being done beneath our own stories, within a website devoted to championing science.
There are plenty of other ways to talk back to us, and to each other: through Twitter, Facebook, Google+, Pinterest, livechats, email, and more. We also plan to open the comments section on select articles that lend themselves to vigorous and intelligent discussion. We hope you'll chime in with your brightest thoughts. Don't do it for us. Do it for science.
