Using Wikipedia: Crash Course Navigating Digital Information #5

[@WikimediaUK]

Thanks from the Wikimedia community! We really appreciate when people create content that helps explain to people how the site works and how people should engage with it. We love what you guys do. We support the Wikimedia community in the UK, but our sister charities run events all around the world if people want to learn how to edit Wikipedia and improve free knowledge online.

Underrated so true

[@krisselissan6539]

Most of my University professors have actually told me that the best way to get started on a project or paper is to either read the wikipedia article on it and then go through its sources, or to just go through the sources. One of my Linguistics professors told us in our first lecture to prepare for the next one by reading the assigned chapter as well as the Wikipedia article on whatever feature we would be discussing. She always begins her lectures with a question round, where you can mention things you read on Wikipedia that were not included in the book. If it’s a false piece of information she corrects it, if not she integrates it into her lecture, which in my opinion is a fantastic method.

[@rdreher7380]

One thing I've often noticed about Wikipedia, it's articles about mathematics are often impossible to understand. They are full of esoteric jargon and explanations, explaining simple things with way more advanced things. I think this likely says something about the kind of people who end up editing these pages, probably people immersed in their field not really thinking about how to explain a concept to those that don't have all their technical background, or maybe are too eager to get down everything about a topic without understanding how much that confuse someone, especially in math. It's a very good point in general that Wikipedia is biased towards having more information on topics that are popular among their community. My impression over the years has been that generally "nerdy" things do quite well. Just an impression though.

[@IronLotus15]

I agree. Only the people that write the damn pages can understand it...

[@somedragontoslay2579]

Yeah! I actually use Wikipedia as my measure of how much I understand something about maths: If I understand it, I'm level God.

[@STAR0SS]

Wikipedia pages aren't courses. They are more like references where you can find the information you need. If I don't remember what the Fourier transform of 1/x is I can quickly check on the Fourier transform page to find the answer. If I don't know what the Fourier transform is I need to take a math class or buy a book.

[@ArawnOfAnnwn]

While that's definitely one reason for such pages, they're also a deliberate choice. Wikipedia intentionally prioritizes accuracy over accessibility, in order to not mislead people. For deep domain-specific pages, like math or chemistry, that means they choose to present the information in its precise, scientific form. Why? Because paraphrasing or simplifying it into plain English often makes it lose its meaning. It's written that way in scientific papers because that's the only way to accurately represent the information, simple language simply isn't upto the task. For example, consider the simple Russell's Paradox. While not math, it does reside in the related field of logic. The Wikipedia page for that is mostly written in plain English, because the paradox is understandable in plain English. However, it also includes the formal notation version of it. This is important as that's really the only reason why the paradox 'really' has power, and is respected as a true paradox in the community. For instance, the famous Liar Paradox that preceded it - "this statement is false" - sounds like a bit of a party trick, just some clever wordplay. Yet it's stood for thousands of years because logicians have recognized it's a lot more than that, it's a real contradiction. Russell's Paradox is similar - it gives off that too clever by half kind of impression. Indeed a lot of paradoxes do. They only count because they've been formally expressed in the precise language of logic and found valid. And many others that can be said in everyday language are considered false because they don't stand in formal logic. Now simple logic is by far more amenable to translation into plain English than complex math. And so the Wikipedia logic pages mostly have simple English explanations. But with advanced math, there's simply no recourse. It often makes no sense in our ordinary fallible natural languages, if it can even be sensibly translated into it. You must have come across plenty of mathematical trickery from your friends while growing up, or in social media memes (for instance, all those fallacious 'proofs' to show that, say, 2=1 or some such thing). It's very easy to come up with that in math, even more so than with clever wordplay in logic, but of course they don't survive proper formal procedures. When explaining to lay audiences, mathematicians usually fall back on analogies and metaphors, but they know well enough that those are imprecise because the actual operation is highly abstracted. Just the act of trying to translate it into normal language causes it to become imprecise, indeed in a sense the 'layman' version is a lie. The lesson to take from this is that those topics aren't for beginners. You're going to have to do a lot of learning to be able to truly understand the highly abstract topics being written about there. Wikipedia is there for you if and when you do understand the subject, but it won't simplify it for you if that fundamentally changes its meaning.

[@somedragontoslay2579]

@@ArawnOfAnnwn While I agree, I think that sometimes wikipedia goes over the top; even things as simple as individual numbers and basic operations start with too much jargon. I don't think those precise details should be avoided on those articles since that's the way to say to the public "Hey, there is more about this topic than that you learned at kindergarten", but maybe they should have their own special section of the article instead of starting so heavy. Either way, I'm happy whenever I understand Wikipedia.

[@rev.rachel]

There are also some university libraries and other academic institutions that are particularly interested in digital scholarship who hire someone as a “Wikipedian-in-residence.” Their entire job is to expand and tweak Wikipedia articles, especially on topics related to specialties of the university’s professors or the items in its special collections, for instance, to increase their reliability and the completeness of their information.

Checking the references is terribly important on Wikipedia. It is common, I find, especially in more controversial articles, for the references cited to support particular statements not only are of poor quality, but frequently do not actually support the statement that cites them. While you certainly told of the importance of checking references, I do wish that you had emphasised this a bit more, perhaps with its own example in the Thought Bubble. But the gist of your article, that Wikipedia is a great source when used correctly, is very much true.

I agree. Encyclopedias are indispensable as starting points for researching a topic, just as a dictionary is the best starting place for words. Even if you think you know a topic or a word, it is a good idea to review it beginning a research project. Wikipedia has been successful, not just because the internet is more powerful than an old fashioned printed book. Its success is mostly because everyone in the world is invited to fact-check it: professors, professionals, journalists, eye-witnesses, etc. Reference sets will always be a necessary educational tool. Wikipedia's use of technology gives it the same advantage Gutenberg's press had over ancient scribes.

If you don’t believe me, look it up on Wikipedia.

[@sandymiller8244]

Why not send your students to library databases where articles are fact checked first? They are typically free and accurate.

[@gianordano]

Sandy Miller That is a great idea. However, most databases, from my experience, are not free and not every school library subscribes. At my current school students do have access to certain databases, mostly newspaper databases. In Sweden, where I teach, there is a online free database containing published academic papers from universities. Ambitious students sometimes go there. But, the point of this video is that Wikipedia is a good place to start. Like Green stated, it’s great for getting a birds eye view. I’m not suggesting Wikipedia should replace other, more credible, sources.

[@sandymiller8244]

@@gianordano I guess I am lucky to have better libraries where I live :). The problem with using a source that may not be correct is that you may have to unlearn incorrect information. If I had a medical problem, I would go to a medical expert first rather than ask someone who does not have authority to provide the information. Good discussion.

[@gianordano]

Sandy Miller You are right to point out the risk of having to “unlearn” wrongful information, but that is more an argument against relying on a single source rather than the reliability of any particular source. Even if you go to a doctor for medical advice I would say it’s sound advice to get a second opinion if it’s an important matter. It doesn’t mean your doctor isn’t a reliable source, simply that you remain skeptical. Same goes for scientific papers. Even if they are peer reviewed and published in a respected journal I would never rely on any single source for reaching a sound conclusion. Also, good talk. I never engage in comments. I might have to do it more often. Of course, I can’t really reach a conclusion based on this single experience. 😏

I've literally used them unchanged before on minor hobby projects and saved a bunch of time. The pseudocode is often pretty good too.

Wiki is also good for quickly wandering through related information. You can start at one layer an easily dig deeper or move laterally in a way that would be hard to equal with online sources and impossible to equal with offline sources. Also, primary and secondary sources are not inherently dependable either. You always have to use your judgement when evaluating new information.

[@dinornis]

If you're a regular user of Wiki and you're signed in with an account, there's a whole bunch of 'Gadgets' you can select - the list is really worth going through for easy navigation! Enabling XTools shows stats about the page history (number of revisions, editors, pageviews, watchers etc) and 'Display an assessment of an article's quality in its page header' gives a rating (such as A/B/C-class) to suggest whether the article may be complete, factually accurate, a stub etc. Fwiw, the note that article quality can be dependant on community is a good one. There's been an ongoing debate as to whether macrons are used in pages containing Māori language, with some pretty dodgy reasoning for dropping the macron (seen as whitewashing by many), and this has caused several pages to be edited back to the 'English' versions. So it's good to acknowledge that there's still a degree of bias that influences articles.

Thanks great example of how to use the Internet. Wikipedia is a great example of open collaborative information - something that would have been difficult to achieve prior to the Internet. It is very different from the concept of vetted/trusted information sources that we used to had to depend on. These are still available; and, some are very good; but, as you pointed out, they can bring their own bias which is not always easy to detect. Wikis do have their challenges; but, they also provide the ability of harvesting the diverse knowledge of MUCH larger pool of contributors. Years ago I contributed some information that that very few people knew and I just happened to know because I was in the right place at the right time. When I am no longer here, that information might have been lost. It wasn't groundbreaking; but, when you multiply that by the billions that use Wikipedia, the opportunity is huge. Wikis are just a tool like any other, they are most useful when kept sharp by caring hands and used by careful and skillful hands. Anyone who finds and error or an opportunity to contribute shouldn't leave the error to have something to complain about; but, rather, make a change and contribute to build for the future.

Teachers warn you not to use wikipedia as a source because encyclopedias aren't sources. They're source aggregators. So start with the wikipedia page you're writing about, read it, then scroll down to look at the sources for the article.

Can you make a video about the use of stock photos?

I've been saying this for years: Wikipedia is superb. I always recommend its use to my students. It is a much more expansive and more frequently updated encyclopedia than its limited and slow-moving printed equivalents. As long as you don't use Wikipedia itself as a source in your work, using the site as a tool to find out more about any given topic, is arguably the first stop for most researchers.

[@sandymiller8244]

In the US, encyclopedias are online and updated frequently by subject matter experts who sign their articles. Librarians can tell you that most encyclopedias have left print format. They are frequently updated and you can contact publishers for corrections and suggestions which prevents information vandalism.

Wait, did John actually delete Hank’s Wikipedia at one point?

[@ScottKorin]

FYI, John's wikipedia no longer mentions that he is an author -- as of September 2018. So this video is old ;)

I love source-surfing on wikipedia.

After this I had to check out the toilet paper orientation thing

For some reason teachers don't like Wikipedia, but Wikipedia's sources are just fine!

[@bee5120]

Exactly! Back in my college days, I always relied on Wikipedia as the starting point for my research papers. The External Links are what leads to actual credible info since most of it lead right back to academic published journals of sciences and psychology.

Again, Wikipedia is the best place to start learning a new subject, but it's possible a lower-quality source can get into an article and stay for a hours or days before another editor notices and corrects it.

[@kevinconrad6156]

True, but the sources sited might also be much more biased than the Wikipedia article that is group corrected. One must always evaluate any new information. For some things like chemical elements Wikipedia is as good as any other source.

[@Tfin]

There shouldn't be corrections that don't have sources that can be cited themselves.

[@vitgerivaz]

Wikipedia has been on a downward spiral as of late it seems, with editors from different political sides manipulating information. Now i finally understad why back in highschool my teachers told me not to use it.

[@joshbobst1629]

Heard on Crash Course tonight: "citizens of the internet". Whew!

[@ReikaSensei]

Good. But even when academic sources are available if the people in the community are unaware of all the sources because they aren't a scholar in the field or because of a language barrier the article can still be wrong or biased unintentionally. This happened at my uni for one course where we had to do a paper about the Tenjin deity and someone used the Wikipedia entry instead of the assigned reading. The next week the professor made us write a one paragraph paper explaining why the Wikipedia article was wrong based on the assigned reading. Now to be fair it isn't 100% wrong in that the content of the article was based off a scroll at the main temple explaining its founding, but the scroll was also propaganda to promote that temple over another shrine built by a woman that pre-dated it and also had inaccuracies that could be proven wrong like dates in Heian historical records. The works are all published in English, but the problem is those academics aren't on the site to fix it. Similar can be said of other Asian media references. Like if you study East Asian lit you know the classics and when something is referenced, but you're not going to find a professor to drop everything and write a paper about how some kids' show is referencing this classic book.

Thank you SO MUCH for this, you making world a better place

[@SpirusOfH]

This series is definitely important to a great many people, but I really found myself thinking "well, duh" a lot of times. A lot of the conclusions have been the axioms that I have lived by for many, many years and I guess I always assumed everyone else did as well.

[@andrewgalati3406]

The Tims in the audience were hoping you would make a reference to the vandalism that takes place on the Grenfell Centre page after every episode of Hello Internet its mentioned in...
