Don't trust Wikipedia when it comes to controversial science topics
Two scientists went out to examine if the downsides of Wikipedia affected scientific articles as well. They chose a few controversial topics, such as acid rain and evolution, and a few noncontroversial topics, such as general relativity, and scrutinized their edit histories spanning back to years, looking for number of edits per day, word counts and page views.
Overall, controversial topics received far greater amounts of editing in greater frequencies than noncontroversial topics. Coauthors Likens and Wilson explained how they found edits that inserted blatantly incorrect information to the articles.
It's no secret that Wikipedia is not a reliable source for academics, but students are still advised to use Wikipedia as a starting point for real research. The authors warn of Wiki's extremely dynamic nature, saying that in a very short period, two students looking at the same topic could receive dramatically different information.
