Why You Shouldn't Trust Internet Comments 180
sciencehabit writes "A new study suggests that all the reviews you read on Yelp and Amazon are easily manipulated. It's not that companies are stacking the deck, necessarily, it's that a few positive comments early on can influence future commenters. In fact, when researchers gamed the system on a real news aggregation site, the items received fake positive votes from the researchers were 32% more likely to receive more positive votes compared with a control (abstract). And those comments were no more likely than the control to be down-voted by the next viewer to see them. By the end of the study, positively manipulated comments got an overall boost of about 25%. However, the same did not hold true for negative manipulation. The ratings of comments that got a fake down vote were usually negated by an up vote by the next user to see them."

Absolutely! Probably the truthiest thing I ever read.

What's interesting about the study is:
1) The manipulation was a single positive or negative vote applied at random immediately when the article went live.
2) People would tend to correct false negatives, but amplify false positives.

My mistake, it's not even articles, it's just Reddit comments.
