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

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]

On the matter of politicians THEY ARE MOSTLY ON THE MONEY!

I have found Wikepedia to be a tremendous first step in any research project. In addition to more than basic information, if suggests avenues for further topics to explore. I refer to Wikepedia several times a week, and have never found any inaccuarcies.

I use Wikipedia all the time for things like movies and learing what the actors have been doing lately, etc; but I would never use if I was writing a paper for my doctoreate. It serves a convenient purpose, and I like the "edit" option which allows the reader to correct certain inaccuracies; but Wikipedia itself will always double check any new information for accuracy. As far as reading it, it's no different from any other encyclopedia. Let's face it; what is more difficult to read than Encyclopedae Britannica?

Good luck with that doctorate - maybe learning how to spell it (as well as 'encyclopedia') might help...
No worries - just teasing ... :-)

"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."
And because of it's extremely limited scope it shouldn't be used as a news article, or even be presented as something of interest.

It's all right for non-controversial topics and factual information, for example, if you wanted information about the star Antares, or when Charlotte Bronte wrote Jane Eyre. I certainly wouldn't trust it for any highly charged topics like a bio of President Obama, or anything where the whackos basically want to rant on their latest whacko conspiracy theory.

Controversial subject are massaged to match the belief of the Wikidedia approved editor and useful only as a starting point becuase personal opinion instead of fact is allowed to be represented. For most other subjects Wikipedia is a superior quik read about the basics.

We should not forget that the acquisition of reliable information still requires some degree of effort. Wikipedia (as far as research is concerned) is -in my opinion- the best thing available to the researching public. It is not perfect, but it will, at least, get you started and, in most cases, put you on the right track. Unless you want Wikipedia to do your research for you, I would say it is doing what it was created to do; and doing it very well.

AND READING THE CELEBRITY DRIVEN GUNK THAT IS SPEWED OVER AOL IS ANY BETTER?....I'D RATHER READ ABOUT THE HISTORY OF TOILETS ON WIKPEDIA THAN YET ANOTHER AOL CRAPOLA BLURB ON THE KELLY RIPA'S OF THIS WORLD!

I would like to see an "unbiased" study of Wiki content on politically charged issues (if that is not an oxymoron) which, these days would include bios on our founding fathers and documents. The huge problem with Wiki is not the accidental, ignorent, or mis-informed edit but the intentional skewing of the facts to suit an agenda, something that can sometimes be done by simply changing a single word.

who would rely on one source for information?
aapmglennJun 6th 2010 11:34AM
I for one trust Wikipedia only for some good first links to real data and actual research. This is a "Cliff Notes" version of info written by people who may or may not be correct. For a particular book I've been writing which requires hard data I've found the amount of incorrect statements on Wiki to be appalling. I've even signed up to be able to correct them...have tried to correct them too...only to see my work re-"corrected" back to the original incorrect info. Use it at your own risk

Media is controlled by the elite so they are scared of wikpedia.
hey hot stuffJun 6th 2010 12:08PM
I think people, including teachers, that dissuede from Wikepedia are just ignorant to the information source. I used to be one of these people that had little faith in Wikepedia until I used it to "prove why Wikepedia isn't accurate." I had made my own eroneous entry in Wikepedia to make my statement and within ten minutes it had been properly edited by Wikepedia. Now I am a believer and a friend to Wikepedia.

I sometimes use Wikipedia as a beginning source when researching a topic. It is fairly concise and give useful references to pursue if needed. I recommend it but never reference it in my work. I always go on an confirm anything i get from Wikipedia because of the possibility of Wikipedia information being corrupted by idiots.

Not easy to read??How stupid can people be??What they need pic's??

I never had any trouble reading Wikipedia. I don't believe most of it as "gospel," but it's fun to look at. Sometimes, I just like to look up stuff for the hell of it. Yeah, I know, I'm weird. I like to read the dictionary too.
