Write My Essay, Please! - The Atlantic

These days, students can hire online companies to do all their coursework, from papers to final exams. Is this ethical, or even legal?
A colleague tells the following story. A student in an undergraduate course recently submitted a truly first-rate term paper. In form, it was extremely well crafted, exhibiting a level of writing far beyond the typical undergraduate. In substance, it did a superb job of analyzing the text and offered a number of trenchant insights. It was clearly A-level work. There was only one problem: It markedly exceeded the quality of any other assignment the student had submitted all semester.
The instructor suspected foul play. She used several plagiarism-detection programs to determine if the student had cut and pasted text from another source, but each of these searches turned up nothing. So she decided to confront the student. She asked him point blank, "Did you write this, or did someone else write it for you?" The student immediately confessed. He had purchased the custom-written paper from an online essay-writing service.
The teacher believed this conduct represented a serious breach of academic ethics. The student had submitted an essay written by someone else as his own. He had not indicated that he hadn't written it. He hadn't given any credit to the essay's true author, whose name he did not know. And he was prepared to accept credit for both the essay and the course, despite the fact that he had not done the required work. The instructor severely admonished the student and gave him an F for the assignment.
But the roots of this problem go far deeper than an isolated case of ghostwriting. Essay writing has become a cottage industry premised on systematic flaunting of the most basic aims of higher education. The very fact that such services exist reflects a deep and widespread misunderstanding of why colleges and universities ask students to write essays in the first place.
These services have names such as WriteMyEssay.com, College-paper.org, and Essayontime.com. Bestessays.com claims that "70% of Students use Essay Writing service at least once [sic]" and boasts that all its writers have M.A. and Ph.D. degrees. Some of these Web sites offer testimonials from satisfied customers. One crows that he received a B+ on a ghostwritten history essay he submitted at a prestigious Ivy League institution. Another marvels at the scholarly standards and dedication of the essay writers, one of whom actually made two unsolicited revisions "absolutely free." Another customer pledges, "I will use your essay writing service again, and leave the essay writing to the professionals."
Such claims raise troubling questions. First, is the use of these services a form of plagiarism? Not exactly, because plagiarism implies stealing someone else's work and calling it one's own. In this case, assuming the essay-writing services are actually providing brand-new essays, no one else's work is being stolen without consent. It is being purchased. Nevertheless, the work is being used without attribution, and the students are claiming credit for work they never did. In short, the students are cheating, not learning.
Most essay-writing services evince little or no commitment to helping their customers understand their essay topics or hone their skills as thinkers and writers. They do not ask students to jot down preliminary ideas or submit rough drafts for editing and critique. They do not even encourage them to pose questions about the subject matter. Instead, the services do all the work for them, requesting only three things: the topic, the deadline, and the payment.
Second, how do these essays manage to slip past an instructor undetected? If most institutions knew their students were using essay-writing services, they would undoubtedly subject them to disciplinary proceedings. But the use of such services can be difficult to detect, unless the instructor makes the effort to compare the content and quality of each essay with other work the student has submitted over the course of a semester. But what if the entire semester's work has been ghostwritten?
Another disturbing question concerns the writers who produce such essays. Why would someone who has earned a master's degree or Ph.D. participate in such ethically an dubious activity? One answer may be that many academics find themselves in dead-end, part-time teaching positions that pay so poorly that they cannot make ends meet, and essay writing can be quite a lucrative business. For students who can wait up to 5 days, one service charges $20 per page, but for those who need the essay within 16 hours, the price quadruples to $80 per page. The "works cited" portion of essays can generate additional revenue. The same service provides one reference per page at no additional cost, but if students feel that they need more citations, the charge is $1 per source. Some struggling academics may also view ghostwriting as a form of vengeance on an educational system that saddled them with huge debts and few prospects for a viable academic career.
A far deeper question is this: Why aren't the students who use these services crafting their own essays to begin with? Some may simply be short on time and juggling competing commitments. As the cost of college continues to escalate, more and more students need to hold down part-time or even full-time jobs. Some are balancing school with marriage, parenthood, and other family responsibilities. The sales pitch of the essay-writing services reassures students that they are learning what they need to know and merely "lack the time needed to get it down on paper."
But more disturbingly, some students may question the very value of writing term papers. After all, they may ask, how many contemporary jobs really require such archaic forms of writing? And what is the point of doing research and formulating an argument when reams of information on virtually any topic are available at the click of a button on the Internet? Some may even doubt the relevance of the whole college experience.
Here is where the real problem lies. The idea of paying someone else to do your work for you has become increasingly commonplace in our broader culture, even in the realm of writing. It is well known that many actors, athletes, politicians, and businesspeople have contracted with uncredited ghostwriters to produce their memoirs for them. There is no law against it.
At the same time, higher education has been transformed into an industry, another sphere of economic activity where goods and services are bought and sold. By this logic, a student who pays a fair market price for it has earned whatever grade it brings. In fact, many institutions of higher education market not the challenges provided by their course of study, but the ease with which busy students can complete it in the midst of other daily responsibilities. The shrewd shopper, it seems, invests the least time and effort necessary to get the goods.
But when students outsource their essays to third-party services, they are devaluing the very degree programs they pursue. They are making a mockery of the very idea of education by putting its trappings - assignments, grades, and degrees - ahead of real learning.. They're cheating their instructors, who issue grades on the presumption that they represent a student's actual work. They are also cheating their classmates who do invest the time and effort necessary to earn their own grades.
But ultimately, students who use essay-writing services are cheating no one more than themselves. They are depriving themselves of the opportunity to ask, "What new insights and perspectives might I gain in the process of writing this paper?" instead of "How can I check this box and get my credential?"
Some might argue that even students who use essay services are forced to learn something in order to graduate. After all, when they sit down to take exams, those who have absorbed nothing at all will be exposed. That may be true in a traditional classroom, but these days, more and more degree programs are moving online -- and in response, more and more Internet-based test-taking services have sprung up. One version of "Take-my-exam.com" called AllHomework.net boasts, "Just let us know what the exam is about and we will find the right expert who will log in on your behalf, finish the exam within the time limit and get you a guaranteed grade for the exam itself."
And why stop with exams? Why not follow this path to its logical conclusion? If the entire course is online, why shouldn't students hire someone to enroll and complete all its requirements on their behalf? In fact, "Take-my-course.com" sites have already begun to appear. One site called My Math Genius promises to get customers a "guaranteed grade," with experts who will complete all assignments and "ace your final and midterm." And why should the trend toward vicarious performance stop with education? How long must we wait until some intrepid entrepreneur founds ""Do-my-job.com" or "Live-my-life.com?"
Meanwhile, the proliferation of essay-writing and exam-taking services is merely a symptom of a much deeper and more pervasive disorder. For that reason, the solution is not merely tougher laws and stiffer penalties. We need a series of probing discussions in classrooms all over the country, encouraging students to reflect on the real purpose of education: the new people and ideas a student encounters, and the enlightenment that comes when an assignment truly challenges a student's heart and mind. Perhaps an essay assignment is in order?

Study Shows Studies Show Nothing - Money Morning

If you’ve ever wondered how a study can show something that just can’t be true, or how studies can completely contradict each other, we’ve figured it out. With a little help of course. After today’s Daily Reckoning, I hope you never believe another ‘study’.
Our heartfelt congratulations go out to Mathgen. A mathematics journal provisionally accepted its paper for publication.
Wait, ‘its’ study?
Yes, that’s right. These days a computer program can write an academic paper about mathematics. Then get published in academic journals like ‘Advances in Pure Mathematics’. And you thought those computer programs dominating the stock market were smart!
No longer are your sons and daughters safe from having to compete with machines in the academic world. That’s another ‘safe’ career choice gone. So what was the paper Mathgen wrote about? Here’s the abstract, which describes it:
"Let ρ = A. Is it possible to extend isomorphisms? We show that D’ is stochastically orthogonal and trivially affine. In [10], the main result was the construction of p-Cardano, compactly Erdös, Weyl functions. This could shed important light on a conjecture of Conway-d’Alembert."
If you’re confused, that’s sort of the idea.
Only a mathematics academic could decipher that abstract, because it’s completely meaningless. You see, Mathgen creates papers by combining random nouns, verbs, numbers, symbols and the rest of it.
It spits out something that makes grammatical sense, not that you’d know it, but is completely devoid of any meaning. The formatting is said to be nice, though.
Once the paper is randomly generated and submitted for the academic journal’s review, the academics safeguarding the gates of science and knowledge read the paper and figure it must mean something.
That’s how the paper gets past the peer review process. The same process that keeps climate change science squeaky clean, by the way. Here’s what the anonymous peer reviewer wrote about Mathgen’s bizarre creation:
"For the abstract, I consider that the author can’t introduce the main idea and work of this topic specifically."
Maybe that’s because there is no main idea. No ideas at all, in fact.
Anyway, once the academics of the peer review process give the paper a once over and decide it’s fine to publish in their illustrious journal, the valuable and useful knowledge in the paper is disseminated around the academic world. That will probably never happen to Mathgen’s paper because the joke was exposed before the journal was finalised.
If all this makes you chuckle and shrug, consider that it’s the norm in academic publishing. A similar computer program managed to get an article about postmodernism published in a Duke University journal. And even when people run coherent scientific experiments (with real people) the results have a habit of being suspect too.
Many studies can’t seem to be replicated these days. Meaning, if you ran exactly the same experiment, you wouldn’t get results that confirm the study’s findings. According to one science journalist, 47 of the top 53 most important cancer studies can’t be replicated. They might be completely wrong, and yet we base modern research on the assumption they are right.
To be clear for any sceptics, the Mathgen paper is a true ‘gotcha’ moment. It wasn’t about the fact that a paper can be written by a clever computer program. It wasn’t about anything. It was complete gibberish. But it did show the fact that academic journals are…academic. Let’s hope nobody reads them.
Unfortunately, finance and economics journals actually do get mentioned in the real world. In fact, their conclusions often determine public policy. Politicians hurl studies at each other proving their opinion.
Luckily for economists, it’s very difficult to disprove an economics study. You never know the ‘counterfactual’ — what would have happened. But if maths and science are corrupted, you’d think economics is corrupted twice over.
So the next time you read ‘a study has shown,’ you can disregard the end of the sentence.

Nick Hubble

How to find Plagiarism in Dissertations - Copy, Shake, and Paste

Germany is awash in another wave of discussions about plagiarism. This time it is the Minister of Education and Research, Annette Schavan. The story about plagiarism in her dissertation broke in May, and the University of Düsseldorf has been examining the case since. Today, October 17, the committee is meeting to decide on the results, but the documentation that they prepared was leaked to the press this past weekend, and the press has been in a frenzy.

And I have laryngitis and can't talk. I have journalists pleading with me to explain how the "magic" VroniPlag Wiki software works. The problem is, there is no magic software. The method used to find plagiarism in dissertations (or any other written work) is called "research". Just normal research.


But since so many people need to know how this is done, here's a crib sheet with 10 easy steps:

  1. Obtain the thesis. If you are just trying to find the dissertation of a particular person who did their doctoral work in Germany, give the German National Library a try. Type in the name and see what it comes up with. Then use the catalog of your local library (often called an OPAC, online public access catalog) or a union catalog to try and locate a copy. Most German states have a union catalog, in Berlin it is the KOBV.  If there is none in your locality, you can obtain a library card and then have the thesis sent to you using inter-library loan.
  2. Read the thesis. There is no royal road. The so-called plagiarism detection software can turn up the odd reference, but only if the sources are online. The best bet is to start reading it, and look for shifts in writing style, or places where the writing turns Spiegel-esque, or for sudden useless details, or misspellings, or just wrong content.
  3. Google. I've given up on other search machines. Just belly up to the search bar and type in three to five words from a sentence or paragraph and see what turns up. If you get a lead through Google Books, use step 1 to obtain a copy of the book. If you get lucky and the first paragraph is taken from the FAZ or the NZZ -- paydirt! Don't just try one paragraph, take a few from different parts of the book. 
  4. Follow the footnotes. University teachers do this when teaching their students how to footnote, and it scares the daylights out of students when they see that the professor found out that they were just making up the footnotes. Does the reference exist? Is the thing being said found on that page? Is the whole paragraph taken from the reference with the quotation marks "forgotten"? Does the chapter in the dissertation continue on after the footnote without a further reference? Is this paragraph perhaps just a translation of the reference? 
  5. Browse the bibliography. What is the most recent source used? Is it five years older than the dissertation? In some fields, this would sound an alarm. Is there some strange or obscure literature listed? Obtain it! Do you need journal articles? Germany had a wonderful listing of the holdings of all libraries nationwide, the Zeitschriftendatenbank. It will tell you where they can be found, and many can even be delivered to your email account as a pdf for a few Euros. Many libraries also subscribe to digital libraries that can be used when sitting at the library. A walk would do you good, anyway, so get over there and have a look.
  6. Digitize. If you have already found a source plagiarized in a dissertation, the chance is that there is more. Have a good look at each, and now digitize the relevant portions. Use a book scanner in the library to get a high-quality scan of the pages as a PDF. You lay the book flat under the camera, press a button, turn the page, press a button, until you are done. Experienced scanners can do over 100 pages per hour. Now use an optical character recognition (OCR) software on the PDF. There are free ones like Google's Tesseract or professional versions such as the one built into Adobe's Acrobat or OmniPage or Abbyy Fine Reader.
  7. Compare. This is one if the few software systems the VroniPlag Wiki people use. It is a text comparison tool that is based on the free algorithm of Dick Grune. The tool marks identical passages in two documents that it is comparing. Put the dissertation in one side, the source in the other, and press "Texte vergleichen!". Don't forget to make a screen shot if the results turn out colorful.
  8. Document. If you find anything, document it exactly. Page and line numbers from the dissertation, URL or page and line numbers from the source, and a copy of each. A two-column side-by-side has proved easy to understand when showing the results to others.
  9. Need help? If you have already found some nasty text parallels, drop in at the VroniPlag Wiki chat or use the drop if you want to be discreet. You might be able to interest someone in working on the case. But remember, they are all volunteers. Or you can continue on yourself, and then inform the ombud for good scientific practice at the university in question.
  10. Publish. If you feel that it is necessary to publish your results, you can either choose a wiki, such as the GuttenPlag Wiki or the VroniPlag Wiki, which makes it easier for others to help you with the documentation, or you can publish on a blog, like the SchavanPlag blog, which gives you complete control of what is published. Or you can print up a book, like Marion Soreth did in 1990 when she documented the dissertation of her colleague Elisabeth Ströker. 
All clear? If I've missed anything, please add in the comments!

Scientific fraud: a sign of the times? - The Guardian

If you read about scientific fraud in the recent news, it would seem that there is much to worry about. It's on the rise, apparently! There has been a 10-fold increase in the number of retracted papers since the 1970's, and a number of these are due to fraud or suspected fraud.

An investigation of retractions from the biomedical scientific literature database PubMed published in the prestigious Proceedings of the National Academy of Science USA (PNAS) found that a whopping 63.2% of health- and life-science related retractions were due to fraud, suspected fraud or plagiarism, with good old honest error retractions in the sound minority. This sounds scary – especially the 'suspected fraud'. Is this just the tip of the scientific deceit iceberg? Just how many lies are lurking in the scientific literature?

Then there are the stories. Professor Marc Hauser (formerly) of Harvard was accused by the U.S. Department of Health and Human Services's Office of Research Integrity of inventing results to support his idea of a biological foundation for cognition in monkeys – specifically if they could recognize changes in sound patterns like human babies can. Hauser was a popular scientist too; he even has a best-selling book: Moral Minds: How Nature Designed Our Universal Sense of Right and Wrong where he somewhat ironically argued that "policy wonks and politicians should listen more closely to our intuitions and write policy that effectively takes into account the moral voice of our species." Which worked out in his case; he was busted for scientific misconduct. His book also tells us that "our ability to detect cheaters who violate social norms is one of nature's gifts". Nature's gifts or not, his students and research assistants blew the whistle.

And this isn't just in life science, it's everywhere. Physics has its high profile cheaters too! There is Jan Hendrik Schön, the physicist who made up his data – 26 of his papers have been retracted and he has been stripped of his doctoral degree. And then there is the cold fusion boys who, to be fair, are probably more victims of faulty equipment and sticking to your beloved theory despite the facts, than perpetrators of actual fraud. Psychology is not immune either; Dirk Smeester, whose results seemed too good to be true, has also been caught just making stuff up.

Is no scientific discipline safe? Are scientists just incapable of keeping their modern houses clean? It has been argued that because of recent pressure for scientists to publish groundbreaking results that change the world, the temptation to commit fraud is perhaps bound to increase, implying that there was a simpler, more honest time for science. Dewy-eyed, there is a temptation to believe that scientists back in the day were only of high moral character and were purely duty-bound to pursue the truth. But this isn't really true. Fraud in science isn't new, just like fraud in anything isn't new.>>>

Misconduct, Not Error, Found Behind Most Journal Retractions - THE CHRONICLE

Paul Basken
Research misconduct, rather than error, is the leading cause of retractions in scientific journals, with the problem especially pronounced in more prestigious publications, a comprehensive analysis has concluded.
The analysis, described on Monday in PNAS, the Proceedings of the National Academy of Sciences, challenges previous findings that attributed most retractions to mistakes or inadvertent failures in equipment or supplies.
The PNAS finding came from a comprehensive review of more than 2,000 published retractions, including detailed investigations into the public explanations given by the retracting authors and their journals.>>>
