Wikipedia Is Accurate, But Not Very Easy To Read, Study Finds

difficulty reading wikipedia
Most people have always been taught to take anything they read on Wikipedia with a grain of salt. The site's usually pretty reliable for general information, or for those times when you need to sound off on the intricacies of Vulcan law. But its open-source format still leaves it vulnerable to a host of factual inaccuracies that usually deter students or academics from citing the online encyclopedia in formal articles. According to one study, though, Wikipedia may be more accurate than we thought -- and a lot more boring, too.

As PhysOrg reports, cancer researchers from Thomas Jefferson University recently compared cancer data on Wikipedia with that published on the National Cancer Institute's Physician Data Query (PDQ), a professionally peer-reviewed, patient-friendly oncology database. After selecting ten different cancer types, and searching both Wikipedia and PDQ for key facts pertaining to each form of the disease, they found that when it comes to accuracy, both sites fared about the same, with only 2-percent of the content of both sites contradicting textbook-confirmed fact.

The main difference, however, was that Wikipedia was substantially more difficult to understand, with much denser, more complex prose. As assistant professor Yacov Lawrence says, "PDQ's readability is doubtless due to the site's professional editing, whereas Wikipedia's lack of readability may reflect its varied origins and haphazard editing."

It should be noted, of course, that this study, presented at the annual meeting of the American Society of Clinical Oncology, was extremely limited in scope. Any entry pertaining to a hard science like oncology is inherently more likely to be weighed down by arcane jargon. It's also a lot less likely that any average user would hold a particularly strong bias on a relatively objective subject like cancer. We're guessing that if these researchers applied a similar methodology to entries on, say, politicians or high-profile celebrities, they'd probably find noticeably more divergence between user-generated content and established, biographical fact.

Within the limited context of the study, though, these results do send a pretty resonant message: when it comes to medicine or medical treatment, it's probably best to seek online information from the experts, and not from each other. [From: PhysOrg and UPI, via: Time]
