10 Controversial Topics On Wikipedia Guaranteed To Spark A Debate

controversial topicsWikipedia is, at its core, a crowdsourced encyclopedia The Origins of Wikipedia: How It Came To Be [Geek History Lesson] Read More . This has its upsides and downsides, allowing a free repository of knowledge to exist for all, but one which has as many critics as fans. Wikipedia is written by a team of unpaid editors, as well as other individuals who contribute as and when they can. Everyone has biases to some degree, but most of the time Wikipedia presents the facts rather than opinion. At least on the surface.


Under the surface there is a war surrounding controversial topics waged on many pages, with editors and contributors drawing battle lines over what should be included and what should be excluded from individual articles. This is especially true of politics, religion, and other taboo subjects liable to cause an argument amongst people sitting around a dinner table.

One way to measure the level of debate attached to different controversial topics on Wikipedia is to track the number of reverts that take place. These are instances when one editor will completely undo another editor’s changes, reverting the page back to its previous state. The authors of a study published at Cornell University Library have used these statistics to compile a list of the most controversial Wikipedia pages across different language versions of the site.

What follows are a list of 10 of these controversial topics on Wikipedia, pulled somewhat at random. These are all subjects you’re likely to have an opinion on, and that opinion will differ greatly from person to person. You’ll think you’re correct in your assumptions, but other people will think they’re correct, even though you have very different views on the subject at hand. It should make for an interesting conversation, at the very least.


controversial topics

Sexual proclivity towards someone of the same gender as you is common and as old as the earliest records kept by humankind. But acceptance of homosexuality has varied throughout history and is now divided by country, religion, and political leaning. Which all adds up to a highly controversial topic argued about between people of differing beliefs and viewpoints.

Anarchism is a political philosophy based on a desire to create stateless societies where authority and hierarchies are eschewed in favor of individuals acting as equal members of a community. The controversy is borne mostly from different schools of thought all of which reside within the umbrella of anarchism. It’s quite ironic that anarchists can’t even agree amongst themselves.

Race & Intelligence

controversial wikipedia pages

The idea that a person’s race can indicate their level of intelligence is one that has existed since the early part of the last century. This idea has previously been used to justify colonialism and slavery and has more recently been used to score political points. The Wikipedia page exploring this controversial topic is rather epic, showing just how much has been written on the subject over the years.


9/11 Conspiracy Theories

controversial wikipedia pages

The official account of the 9/11 attacks which took down the World Trade Center in New York in 2001 states that a cell of Al-Qaeda terrorists hijacked planes and flew them into the Twin Towers. Despite (or perhaps because of) two wars being launched on the strength of this, many people think there is more to the story. The conspiracy theories are numerous and range from the bizarre to the (frankly) quite believable.


controversial wikipedia

Muhammad is a historical religious and political figure who is believed by Muslims to be a prophet of God. People who practise Islam believe that the Quran is made up of the words of God as revealed to Muhammad. The controversial nature of the Wikipedia page dedicated to Muhammad derives from different religions having different beliefs about the man, his message, and his level of importance to the world.



controversial wikipedia

Jesus is a historical religious leader who acts as the central figure of Christianity. Most Christian religions believe Jesus Christ to be the Son of God, while in Islam Jesus is considered a prophet. The controversial nature of the Wikipedia page dedicated to Jesus derives from different religions having different beliefs about the man, his message, and his level of importance to the world.

George W. Bush

George W. Bush was the 43rd President of the United States of America, running the country between 2001 and 2009. His first term was dominated by the 9/11 attacks and the resulting War on Terror. Towards the end of his second term the U.S. entered a recession. Opinions on Bush and his policies differ depending on political points of view, and how he’ll be viewed in history is open to considerable debate.



10 Controversial Topics On Wikipedia Guaranteed To Spark A Debate homeopathy bottles

Homeopathy is a system of alternative medicine that originated in 1796. It’s based on the idea that repeatedly diluting a certain substance in water can create potent remedies. Many people believe in the power of homeopathy, but its virtues are not supported by the wider scientific community. Modern studies have shown a placebo effect occurring, but any more than that is open to interpretation.

Scientology is a religion created by science-fiction writer L. Ron Hubbard in the 1950s, and another controversial topic on Wikipedia. The Church Of Scientology is the largest organization promoting this belief system, with followers in many countries around the world. Many people do not believe that Scientology should be classified as a religion, but that hasn’t stopped millions of others from believing in the teachings.

Global Warming

controversial topics

Global warming refers to the rise in the temperature of the Earth’s atmosphere that has been taking place for the last few decades. While most scientists believe the rise is mainly due to the actions of mankind, some do not, believing instead that this is an entirely natural phenomenon. This is the basis for the controversy, with the two sides completely at odds over the causes and urgency of acting to reverse the process.


I had my doubts about writing this article for fear of offending anyone who has entrenched views on one or more of these controversial topics. But in the end I realized that is the point of the whole exercise. These subjects have all had numerous pages of copy dedicated to them and yet there is still disagreement amongst scholars and amateurs over what is factual and what is mere conjecture. Which makes them fascinating subjects to explore on Wikipedia 7 Ways To Learn Something New Every Day With Wikipedia Wikipedia is packed full of content.

But beware, someone else may have polar opposite views from you on the subject, so prepare to argue your case. Or you could, as I tend to, accept that people will believe what they want to believe, and arguing online The Top Three Sites To Debate Topics With Others Read More is about as likely to produce a satisfactory outcome as would brewing tea in a pot made out of chocolate.

    Controversy at it's finest and Debate in it's glory

    This is Taha Yasseri, from University of Oxford
    I'm the first author of the study on controversial topics in Wikipedia
    This is an awesome work featuring our study very well.
    However, I realised you introduced our work as " a study at Cornell University in New York "
    Actually, none of us is from Cornell,
    2 from Oxford, 1 from Budapest uni of Tech and one from Rutgers.
    arXiv is a public repository provided by Uni Cornell library.
    Basically every researcher from all around the world could put pre-prints and free copies of research there for public audience, so we did too.
    That would be awesome if you could revise your post in order to provide more accurate information about the research team.
    thank you again for your post and best wishes.

      My apologies for the errant wording on the link. Have fixed it now, stating that the study has been published at the Cornell University Library. Anyone clicking the link will see who authored the study and be able to investigate further.

      Thanks for your comment and for placing the study in the public domain.

    The sad part is that these pages shouldn't have to be such a source of debate in the first place. Wikipedia should be a place of factual information only, and should be free of bias. If these editors are going back and forth with their biased factual information, then they probably shouldn't be editors in the first place.

      "biased factual information"
      That is a contradiction in terms. If it is "biased", it is not factual. If it is "factual", it is not biased.

      "Wikipedia should be a place of factual information only"
      The last purely factual book I saw was a a list of mathematical values. If you look through the ultimate encyclopedia, Encyclopedia Britannica, you will find bias. Some of the bias is due to authors and editors but some of the bias will be yours. No human can be objective. Because of our life experiences we have all developed biases, whether we recognize that fact or not. We are all biased in one way or another. Any time you express an opinion you are showing a bias. In addition, language is not a precise means of communication. The same word has a different meaning for different people. Each meaning introduces another bias.

        Of course Wikipedia isn't made entirely of factual information and of course it is biased. I only meant that the editors shouldn't go back and forth deleting and re-editing pages continuously. They should attempt to find the most neutral ground possible.

          Since most of the editing on Wikipedia is done by the users, each user changes the entries according to his views. Obviously they don't have to agree.

          The problem is editors have different viewpoints, and so one will completely obliterate the changes made by another because they don't agree. It's all a matter of perspective.

      Of course, you're right. These are all controversial topics online and offline, it's just that Wikipedia provides a way of measuring how controversial they are.
