An anonymous reader shares a report on Quartz:In a sea of biased content, Wikipedia is one of the few online outlets that strives for neutrality. After 15 years in operation, it’s starting to see results. Researchers at Harvard Business School evaluated almost 4,000 articles in Wikipedia’s online database against the same entries in Encyclopedia Brittanica to compare their biases. They focused on English-language articles about US politics, especially controversial topics, that appeared in both outlets in 2012. In its initial years, Wikipedia’s crowdsourced articles were tinted very blue, slanting more toward Democratic views and displayed greater bias than Britannica. However, with more revisions and more moderators volunteering on the platform, the bias wore away. In fact, the upper quartile of the Wikipedia’s sample had enough revisions that there was no longer any difference in slant and bias from its offline counterpart. More surprisingly, the authors found that the 2.8 million registered volunteer editors who were reviewing the articles also became less biased over time.
