If you're using the crowd-sourced encyclopedia Wikipedia to diagnose your health problems, you're likely coming up with the wrong information.
A study just published in the Journal of the American Osteopathic Association tested the reliability of Wikipedia entries. Researchers looked at the 10 most costly medical conditions like lung cancer, back pain, and osteoarthritis. They found the online entries contradict medical research from peer-reviewed journals 90 percent of the time.
Information on nine out of the ten entries had errors, according to the study.
Wikipedia has its own peer-review process for articles and one of the editors for the site says even as its quality improves, patients should always use professionals to get the best recommendations.
