It enables new subreddits to crop out and have support.
People are much more willing to participate in a thing, like to moderate a subreddit. "I think the term hivemind is used pejoratively, and people forget all the things it enables."Īnd, Martin argues, the effect is not all bad: "I think the term hivemind is used pejoratively, and people forget all the things it enables. The researcher's extra upvote seemed to convince many nonvoters to join in, and it also encouraged positive votes from those who might have otherwise voted negatively or abstained. "There was evidence of both opinion change and voter turnout," Aral says. There are certainly some aspects of an echo chamber."īy separating the users they sampled into those likely to vote positively and those likely to vote negatively, the researchers broke down the herding effect into a combination of two behaviors. "It doesn't surprise me that comments that get a positive vote have that momentum. "Twenty-five percent sounds about right," says Erik Martin, the general manager of Reddit. While the researchers are the first to quantify this up/downvoting online herding effect, it may not come as a surprise to many redditors-on the site, the tendency to groupthink is commonly referred to on the site as the hivemind. are beloved almost beyond criticism, and many traditionally liberal political and social views dominate conversations. Astrophysicist Neil deGrasse Tyson and comedian Louis C.K. Reddit is occasionally chastised, even from the inside, for sameness in opinions and groupthink. "One explanation is that people will go along with positive opinions but are more skeptical of the negative opinions of others." The Hivemind "Basically there was a correction effect," Aral says. Instead, the researcher's artificial downvote made users slightly more likely to respond positively, essentially negating the researchers' interference. Oddly enough, this snowballing didn't work in reverse-nobody was ganging up on commenters unfairly based on a downvote or two. I was surprised to find that a single positive vote could create such a huge snowball effect." The researchers discovered that by increasing a comment's score with a single vote, they would boost its final score by an average of 25 percent.
"I was surprised to find that a single positive vote could create such a huge snowball effect." Four percent of the comments were given a positive edge (a single upvote) while another 2 percent were struck with an immediate disadvantage (a lonely downvote). Over six months, the research team took a small percentage of more than 100,000 written comments and slightly altered their vote rating as they were submitted. Here's how it worked: The researchers convinced an anonymous website–under the promise it would remain nameless–to allow them to test slight manipulations in online voting. "We used a site very similar to Reddit," Aral says. It helps us understand how websites can avoid this type of bias in the future," says Sinan Aral, a coauthor of the paper and social-media researcher at MIT and NYU. "It's important to understand the underlying mechanisms of how people vote. For some users in the study, seeing a single extra upvote very early in a comment's life could change their mind about how they felt about a comment, regardless of what the comment actually said.
They found that groupthink plays a surprisingly large a role in how an online communities like Reddit make quality judgments. Three business researchers, led by Lev Muchnik at the Hebrew University of Jerusalem, conducted their own online voting aggregation experiment, the results of which came out today in the scientific journal Science. It's a system that ensures that the best, most insightful, or most representative material rises to the top. Highly ranked news and content float to the top of the site, and highly rated comments float to the top of their threads. Each user can give a post or comment an upvote of approval or a downvote of disapproval. Like Yelp, IMDb, or, the site runs on the principle of voting aggregation. Today, 6 percent of all adult American Internet users are on Reddit.
