As you probably know, the concept behind the popular online encyclopedia Wikipedia is that anybody can add to or change its contents. This results in a huge and powerful knowledge base culled from the varied interests and expertise of its worldwide members.
But this also raises questions about the reliability of such information. Recently, Cal Tech student Virgil Griffith has asked that same question and tried to answer it. Griffith has created a website called Wikipedia Scanner that makes the history of these changes transparent by exposing the changes that come from IP addresses within companies. This way, even when someone is making changes to Wikipedia anonymously, we can match those changes with the source they are coming from. For example, with a search on Diebold on the Wikipedia Scanner, you can find out that the company has excised an entire “Criticism” section from the Diebold entry (which has since been restored). Similarly, Wal-Mart has inserted statements that provide a positive spin on the company, replacing “Wages at Wal-Mart are about 20% less than at other retail stores,” with “The average wage at Wal-Mart is almost double the federal minimum wage (Wal-Mart).”
Knowing as much as possible about the source of your information is one of the keys to doing top-notch research. Thankfully, we have new ways of harnessing this incredible source without so easily falling into its traps.
