“Please help me. I got an F on my paper because I cited Wikipedia.” Jimmy Wales, the founder of Wikipedia, recently lamented that he gets 10 e-mails of this sort every week. And yet, despite Wales' own stated views that Wikipedia provides “good enough” knowledge, students keep using it – and teachers keep giving out Fs. This lesson illustrates the potential pitfalls of Wikipedia. Drawing on two controversies – Stephen Colbert's on-air altering of his own entry and his call for viewers to alter a second entry, and the false biography of John Seigenthaler – students will discuss the ease with which false or misleading information can be added to Wikipedia, and they'll search Wikipedia entries for inaccuracies.


In this lesson, students will:

  • Examine the ease with which Wikipedia entries can be altered (either innocently or maliciously).
  • Discuss the accuracy of Wikipedia as an encyclopedia and consider the usefulness of any encyclopedia as a source of information.
  • Search Wikipedia for specific factual errors.


One of the biggest errors in reasoning is accepting the word of others when you should be suspicious. These errors can be compounded when those making the statements are (allegedly, anyway) authorities on the subject. Often, it's hard to determine what exactly makes something or someone count as an authority. Students (especially younger students) often assume that encyclopedias constitute a real authority. It's not surprising, then, that many students assume that the ultimate Internet encyclopedia – Wikipedia – is authoritative.

When my physics teacher tells me that the speed of light is 299,792,458 meters per second, then I am probably justified in accepting that figure as accurate. Similarly, it's very likely safe for me to cite the Encyclopedia Britannica as evidence that Charles Dickens died on June 9, 1870.

Reliance on the expertise of a source can be a booby trap for the unwary, of course – if the expert in question is not really an authority on the issue in question, or if there really are no established experts in the area. So citing Linus Pauling (winner of a Nobel Prize for inorganic chemistry and a Nobel Peace Prize for his campaign against nuclear testing) as a reason for consuming large quantities of vitamin C is inappropriate.

Similarly, the mere fact that the Pope claims that birth control is immoral is not a well-founded reason for thinking it true.

The problem with Wikipedia, however, is that it is impossible to determine whether an article has been written by Linus Pauling, nobel laureate or Linus Pauling, vitamin C flake. Indeed, Wikipedia editors can be extremely well-intentioned. But they can also be malicious and/or self-interested, as a new tool from CalTech graduate student Virgil Griffith shows. Griffith's search tool allows anyone to discover the IP address from which Wikipedia edits originate and then offers the additional step of identifying the organization or company that owns the particular IP address.'s fact checker identified some of the more egregious self-interested edits (the Post's chart is reproduced in student handout #2). Wired magazine asks users to vote on “the most shameful Wikipedia spin jobs.” The current top vote-getters can be found on the Wired site.


Make a packet containing student handouts #1 and #2 for each student. Make a packet containing student handouts #3 and #4 for each student. Distribute the first packet at the beginning of Exercise #1. Distribute the second packet at the beginning of Exercise #2.


1. The Colbert Report, “Wikiality.”
2. Student Handout #1:, “The Wikipedia Editing Model.”
3. Student Handout #2:, “Suspicious Wikipedia Edits.”
4. Student Handout #3: John Seigenthaler Sr., “A False Wikipedia 'Biography'.”
5. Student Handout #4:, “Seigenthaler Controversy.”


Exercise #1 – Fun with Wikiality

To the teacher: One of the first tasks in learning to recognize good authorities is learning to recognizing where information actually comes from. A case in point is the ubiquitous Wikipedia. Although Wikipedia can be a useful source of information, it is not, and cannot be, authoritative. This exercise will assist students in learning the drawbacks to relying on Wikipedia.

Show students the Colbert Report clip, “Wikiality.” Next ask students to read Wikipedia's own description of its editing model. Then ask students to look at the Washington Post fact checker chart showing some Wikipedia edits along with the source of those edits. Divide the class into small groups of 3 to 5 students each and ask them to discuss the following questions:

1. Where does Wikipedia get its information?
2. Who is in charge of deciding what goes into an article and what gets removed from an article?
3. If there is some debate about whether a particular bit of information should or should not be included in an article, what is the process for deciding?
4. Is Colbert's assessment that Wikipedia is “bringing democracy to knowledge” an accurate one?
5. If so, is that a good thing or a bad thing?
6. What does the Colbert clip lead you to think about the reliability of Wikipedia?

Have the students report their findings back to the class.

Exercise #2 – Spotting Errors

To the teacher: In the first exercise, students learned just how easy it can be to insert false information into Wikipedia. The deeper lesson to be learned is that while inserting false claims is easy, detecting those false claims is much, much harder. This exercise will require students to comb through Wikipedia in order to find some false claims.

In October 2005, John Seigenthaler Sr., a journalist and one-time aide to Robert Kennedy, discovered that his Wikipedia biography contained false and potentially libelous information. That information had been posted as a prank and had remained undetected and unaltered since May 2005. Eventually Seigenthaler had the entry corrected, and Wikipedia editors took the unusual step of hiding the faulty information. The prankster eventually came forward and apologized, and Seigenthaler graciously accepted the apology.

If you have not already done so, pass out student handouts #3 and #4. Ask the students to read Seigenthaler's original complaint as well as Wikipedia's entry on the controversy. Divide the class into small groups of 3 to 5 students each. Ask the students to discuss the following:

1. How reliable do you think Wikipedia actually is?
2. How would you know whether a particular article really is accurate?
3. How would you go about discovering whether an article contains inaccurate information?

Once students have constructed their method for discovering inaccuracies in Wikipedia, have them put their theories to the test. Each group should go find an inaccuracy in Wikipedia. It doesn't have to be a current inaccuracy; it can come from the history pages. If students are having difficulty locating false information, suggest that they look through the history pages on various controversial subjects. Evolution, global warming and stem cells are all good places to start. The page on Christopher Columbus was the subject of a rather infamous round of revisions, in which revisionists inserted the claim that Columbus was a slave trader, editors removed the claim (based on a total lack of evidence) and then revisionists reinserted it. Eventually editors had to lock the article.

After students have found an example of an error, have them report their findings back to the entire class. Students might then discuss the pluses and minuses of Wikipedia. Bottom line: It provides an excellent starting point to examine a subject about which one knows very little, but it should not be taken as definitive. Facts in Wikipedia always require corroboration.
