Everybody who's written or blogged about climate change on a prominent website (or, even worse, spoken about it on YouTube) knows the drill. Shortly after you post, the menagerie of trolls arrives. They're predominantly climate deniers, and they start in immediately arguing over the content and attacking the science—sometimes by slinging insults and even occasional obscenities. To cite a recent example:
What part of "we haven't warmed any in 16 years" don't you understand? Heh. "Cherry-picking" as defined by you alarmists: any time period selected containing data that refutes your hysterical hypothesis. Can be any length of time from 4 billion years to one hour. Fuck off, little man!﻿
It was reasonably obvious already that these folks were doing nothing good for the public's understanding of the science of climate change (to say nothing of their own comprehension). But now there's actual evidence to back this idea up.
In a recent study, a team of researchers from the George Mason University Center for Climate Change Communication and several other institutions employed a survey of 1,183 Americans to get at the negative consequences of vituperative online comments for the public understanding of science. Participants were asked to read a blog post containing a balanced discussion of the risks and benefits of nanotechnology (which is already all around us and supports a $91 billion US industry). The text of the post was the same for all participants, but the tone of the comments varied. Sometimes, they were "civil"—e.g., no name calling or flaming. But sometimes they were more like this: "If you don’t see the benefits of using nanotechnology in these products, you're an idiot."
The researchers were trying to find out what effect exposure to such rudeness had on public perceptions of nanotech risks. They found that it wasn't a good one. Rather, it polarized the audience: Those who already thought nanorisks were low tended to become more sure of themselves when exposed to name-calling, while those who thought nanorisks are high were more likely to move in their own favored direction. In other words, it appeared that pushing people's emotional buttons, through derogatory comments, made them double down on their preexisting beliefs.
