Why You Should Not Use Wikipedia As Your Primary Source

Estimated Read Time: 4 minute(s)
Common Topics: band, level, electron, errors, energy

It is no secret to anyone who has read my posts in this forum for a while that I do not like Wikipedia. I think that there’s a fundamental flaw with the whole concept and philosophy of it. While I think that it may be useful to many who need a quick lookup for something, it is unfortunate that even more are using it almost as their primary source of information. This is scary considering that (i) the validity of the information being presented is never guaranteed and (ii) the pedagogical presentation of the material is often shoddy, making the subject even more confusing.

I often get asked to look at such-and-such Wikipedia entries, or someone is trying to convince me of something and using a Wikipedia entry as a “reference” to back up his/her argument. It is usually during such instances that I find inaccuracies, confusing statements, and outright errors in such entries. I was doing my search on something a few minutes ago, and I decided, out of curiosity, to see what Wikipedia has to say about “Work Function”. Now, keep in mind that this is a common terminology, especially for physics students, since the photoelectric effect is a “must-know” topic for these students. One would think that this should be a topic that a Wikipedia entry would get it right, considering how many people would look up such a thing, AND, the fact that errors and inaccuracy would, by now, be ironed out.

WRONG!

This is what I first saw on the Wikipedia page on Oct. 8, and my last check today shows that it is still there.

work function wiki page

I posted the date in the screen capture as a date stamp on when this was first viewed.

The offending passage has been highlighted with a red box. Let’s look at it closely, shall we?

The description here is on what happened for an insulator (or a semiconductor, for that matter). The figure shown is the simplified band diagram for such a system (i.e. an intrinsic semiconductor, for example), and defines the various quantities such as the work function, bandgap, electron affinity, etc. The problematic statement says this:

For an insulator, the Fermi level lies within the band gap, indicating an empty conduction band; in this case, the minimum energy to remove an electron is about the sum of half the band gap and the electron affinity.

The first part of that paragraph which says “…. For an insulator, the Fermi level lies within the bandgap, indicating an empty conduction band …” is OK. However, the second part is very puzzling and an outright error: “… in this case, the minimum energy to remove an electron is about the sum of half the bandgap and the electron affinity …”

Whoever wrote this is STILL thinking that the work function (Phi) is still the minimum energy needed to produce photoemission, as in the case of a metal. This is FALSE, and anyone who looks at the band diagram can tell. Half of the bandgap plus the electron affinity is the work function Phi, but this is the energy between the vacuum level and the Fermi level. The Fermi level for insulator/semiconductor has NO STATES, and thus, no electrons to excite! After all, it resides in the bandgap! So what is being excited here?

For an insulator/semiconductor, while the work function may still be defined as the energy between the Fermi level and the vacuum level, it no longer corresponds to the photoemission threshold! The photoemission threshold now is the full band gap energy PLUS the electron affinity. You need to excite, at the minimum, the electrons from the top of the valence band to the vacuum level. One can see this clearly by looking at the band diagram in the figure.

Now, you can tell me “But ZapperZ, why can’t you correct these errors, and provide a service to the community?” You will then have missed my point entirely. My problem isn’t with these errors. My problem is the WHOLE PHILOSOPHY of Wikipedia. I find that to be the fundamental flaw, that no one of any authority is being given the ability to write and edit stuff. The errors in the various entries are only the SYMPTOMS of the flawed philosophy. I could spend a lifetime correcting many of these errors (now why would I want to spend a lot of my time to do that in the first place, no one has given me a good reason), and it would not change a thing about my perception of Wikipedia.

If you don’t know the topic you are looking up, and you are using Wikipedia as your PRIMARY SOURCE OF INFORMATION, I would be very scared if I were you.

    [QUOTE=”micromass, post: 5198275, member: 205308″]Yes, because Zz refered to the “whole philosophy” of wikipedia with respect to primary resources. There are other things wrong with the philosophy of wikipedia, but this thread IS about wikipedia as primary resource.[/QUOTE]

    The alternative reading, quite plausible is that he disagrees with the whole philosophy of Wikipedia, and that the misuse by some is only part of his disagreement.

    If you read the quote by Evo in the post above, this is borne out by the use of “especially”.

    Furthermore, the sentence with “WHOLE PHILOSOPHY” is separate, and the term has every single letter in capitals.

    A printed encyclopdia can have errors, but the errors can be pointed out and the printed version can’t be altered, so the corrections stand. This is not true of wikipedia where the entries can be changed daily, most users don’t know that they can look at the history of changes, much less know which changes are correct.

    Well, to be fair to the lecturer, he did correct himself the next lecture. He was a world class yeast geneticist, but the portion he messed up on was population genetics.

    A number of years later, I had to teach freshman physics to a very, very small class, which I imagined should be no problem. But for some reason, I’d never done fluid mechanics properly, and spent I think a whole weekend or much more sweating to understand the chapter in Young (standard freshman text).

    I’ve been here long enough to have encountered people whose whole “world of science” is nothing but Wikipedia! And when someone tries to argue with you by citing a faulty Wikipedia entry more than once, you get VERY tired at not only trying to correct this person’s wrong ideas, but also trying to explain why that Wikipedia entry is wrong! We shouldn’t have to do double work because of that.

I had a friend who edited the biography of a famous person (not a STEM topic), and it included a first-hand eye-witness account of an incident at an event. A week later, he saw that his entry had been deleted, modified, and changed into something that contradicted what he saw, and all were based on 2nd hand, and shoddy “news” account. That was the start of a series of back-and-forth argument involving several different parties that mangled that Wikipedia page.

    Ha Ha. fair enough. I can’t imagine anyone would use it as a source in a scholarly paper, unless it was to point out how “generally accepted by most folks as true” something was. I was thinking of it in the context of a wide ranging learning conversation – like the ones that happen on this forum, and I was thinking of primary as “first”.

    It is great as a first resource because of what I said – It is navigable and it goes everywhere. It’s like the ultimate TOC, or card catalog. I often find myself learning about something completely different than what I began looking for just by clicking on words I don’t understand – and from that I’m learning the dependency tree, which is half the battle.

    I don’t think that accuracy is the [I]only [/I]goal (or even the primary goal) of a live interactive, cross-linked, globally-accessible free encyclopedia – unlike anything the world has ever seen.

    I believe it represents the first modern learning system – I love it because it is an “open-world” of associated concepts with introductory (or better) explanations for just about anything and everything, at the tips your fingers, steered only by your uncertainty and curiousity. It’s extensibility and potential for contributing to education are limitless.

    I am grateful to the people who honestly try to make it better – like correcting content to match the canon, calling out controversial stuff, policing the contribution process, adding awesome graphics and pictures, linking every page to deeper more orthodox content. I believe they are the ones with my interests at heart.

    I contribute money to it regularly. Maybe rich educational institutions should do the same.

    And good luck railing against it.

    [QUOTE=”mathwonk, post: 5197969, member: 13785″]With this insight, I edited the wiki article for the classical case of curves, making a few changes to correct misconceptions that persist among people who have not actually read Riemann’s own account, and a few attempts to render the text more concrete and down to earth. Then I retired from the fray, only to see someone come in almost immediately and remove some of the correct statements I had made, and replace them again with the usual misconceptions and needlessly abstract formulations. What appears there now, much later, is a brief, clear but unmotivated and unsubstantiated standard summary such as one might read in any elementary text or undergraduate thesis, but without proofs. So I definitely would not consult wikipedia for an authoritative account of subjects I already know enough about to write articles on them myself.[/quote]

    This is what I listed as #1 on the faulty philosophy of Wikipedia. And truth be told, it was the impetus on why I wrote that original article (it was actually an entry in the old PF Blog). I had a friend who edited the biography of a famous person (not a STEM topic), and it included a first-hand eye-witness account of an incident at an event. A week later, he saw that his entry had been deleted, modified, and changed into something that contradicted what he saw, and all were based on 2nd hand, and shoddy “news” account. That was the start of a series of back-and-forth argument involving several different parties that mangled that Wikipedia page.

    I followed this as long as I could stand, and that was when I decided to write that article years ago. And this was after someone was using a Wikipedia page as a source to argue against me on a topic I know very well. So there was a double-coupon reason to write this.

    Zz.

    P.S. My invitation to scrutinize that Photoelectric Effect page on Wikipedia still stands. I promise, I am not trying to trap you here. I need to know if you (i) understand the physics (ii) actually understood what it is trying to say and (iii) if you spot errors or something funny.

    That’s what I use Wikipedia for, when I can’t or won’t read an entire book or article to find something small that I want to learn or share. It is usually direct and to the point, and once you then know the basic terms or concepts you can google for other sources for confirmation or elaboration.

    From reading the first part of Zapper’s article, he seems to me to be saying that one should not depend on wikipedia, if one really wants to understand something and be confident about it. Even though I do consult wikipedia at times for a quick version of something, I tend to agree, and think his warning is an important one for learners.

    As an example of mine, I once edited the article on wiki for the Riemann – Roch theorem, especially for curves, and some generalizations. I am not an expert, since I have done no research on this subject, but its use figured in my research almost every day for some 40 years, and I have studied it in primary sources and authoritative texts by experts such as: Riemann (the original preliminary source), Roch (the second and final original source), Weyl, Siegel, Gunning, Mumford, Walker, Fulton, Hartshorne (I also audited his course about 1967), Arbarello, Cornalba, P.A. Griffiths, Hormander, Springer, Seidenberg, J. Harris, Miranda, Mayer, Mattuck, Atiyah, Chern, Hirzebruch, Kodaira, Serre, Zariski (I also heard him lecture on it in about 1966), Van der Waerden, Lang, Macdonald, Chevalley, Beauvile, Kempf,… I also spent part of one summer writing a set of notes on the theorem and posted them on my website.
    (I have not however studied perhaps the most significant work generalizing this theorem in the last 60 years, the work of Grothendieck, exposed by Borel and Serre in 1958.)

    After all these years of studying secondary sources, following courses, teaching and using the result in my research, and writing it up, I only felt I really understood the theorem when an English language version of Riemann’s collected works became available in the last decade, and I studied the original articles closely, after being chosen by Math Reviews as the official reviewer.

    With this insight, I edited the wiki article for the classical case of curves, making a few changes to correct misconceptions that persist among people who have not actually read Riemann’s own account, and a few attempts to render the text more concrete and down to earth. Then I retired from the fray, only to see someone come in almost immediately and remove some of the correct statements I had made, and replace them again with the usual misconceptions and needlessly abstract formulations. What appears there now, much later, is a brief, clear but unmotivated and unsubstantiated standard summary such as one might read in any elementary text or undergraduate thesis, but without proofs. So I definitely would not consult wikipedia for an authoritative account of subjects I already know enough about to write articles on them myself.

    On the other hand, when I wanted to know some formulas for volumes of spheres in higher dimensions for a geometry class I was teaching, I found an excellent, clear and comprehensive statement in wikipedia, which I then checked myself by giving proofs of my own devising.

    It seems that the wiki articles I have read on subjects that I understand best, are written by students or energetic amateurs who give an account of versions of the material they have read up in standard books. On topics I am not so competent in, I cannot judge whether they are written by experts, but it seldom seems the case when I am able to judge.

    So I find wikipedia useful in areas where I am deficient, which is most, to provide brief statements of facts, (not always accurate), but a bit below par in the few areas where I am much more informed than average. Thus I would suggest using it as a sort of Schaums outline series, a source for quick and ready summaries of information, but in cases where one aspires to become expert oneself, I agree one should certainly read instead sources whose authors are known specialists and experts, if not the original source by the discoverer, i.e. primary sources. The danger may be that since one cannot become a scholar by depending on wiki, its overly widespread use may thus lead to a decline in scholarship. Perhaps this is what concerns ZapperZ.

    By the way, if you want a good account of the classical Riemann Roch theorem, I recommend the one in the book of Griffiths and Harris, as closest in spirit to the original.

    [QUOTE=”micromass, post: 5197894, member: 205308″]There are many good reasons why the Feynman lectures should not be used as an introductory physics book. One of the reasons to convince you should be that the original Feynman lectures at caltech were a failure. There are other reasons too.

    The Feynman lectures ARE a superb resource, but you should be careful in how to use them. For example, you get a standard book like Halliday and Resnick (for intro physics), Kleppner (for mechanics), Purcell (for E&M), etc. You read a chapter in these books, do the problems, etc. Then you can check Feynman to see what he has to say about it. This way, you are using Feynman as a secondary resource. This is an amazing way to learn physics. But only relying on Feynman would be rather disastrous.

    The same thing holds for wikipedia really. You get a standard book. You read a chapter, do the problems, etc. Then you can use wikipedia to check what they have to say about it. I do not have a problem with this approach since I do things this way myself. But then you are using wikipedia as an auxiliary resource, you would primarily be relying on the book.

    He is attacking Wikipedia’s “WHOLE PHILOSOPHY”, so he is assigning the blame for the misuse of Wikipedia to Wikipedia, not to the erroneous philosophy or those misusing it. It would be like attacking the “WHOLE PHILOSOPHY” of the Feynman lectures, because some student learnt something wrong from it.

    Here is a description of the basic mistake in the earlier editions of the Feynman lectures:

    This second error was pointed out to Feynman by a number of readers, including Beulah Elizabeth Cox, a student at The College of William and Mary, who had relied on Feynman’s erroneous passage in an exam. To Ms. Cox, Feynman wrote in 1975,[URL=’http://www.feynmanlectures.info/flp_errata.html#_ftn1′][1][/URL] “Your instructor was right not to give you any points, for your answer was wrong, as he demonstrated using Gauss’s law. You should, in science, believe logic and arguments, carefully drawn, and not authorities. You also read the book correctly and understood it. I made a mistake, so the book is wrong. I probably was thinking of a grounded conducting sphere, or else of the fact that moving the charges around in different places inside does not affect things on the outside. I am not sure how I did it, but I goofed. And you goofed, too, for believing me.”

    But now I would be using you as a “sole source” for that :)

    I think relying on sole sources in general is problematic. Even the wonderful Feynman lectures had mistakes – and no, I’m not talking about the the potentially controversial parts on quantum mechanics – there was an error in Feynman’s treatment of Gauss’s law, which Feynman clearly understood deeply, but was careless in that presentation.

    Secondly, ZapperZ is not arguing that Wikipedia not be used as a sole source because of its errors. He is concerned with authority. But in general, and certainly in maths and science, it is logic and evidence that one should be concerned with, not authority. So I cannot agree with his attack on Wikipedia’s “WHOLE PHILOSOPHY” and the misleading insinuation that Wikipedia suggests that it be used as a sole source.
