My situation is somewhat similar to this question, but I'm the plagiarizer.

Six years ago I did my Master's degree by coursework at university X, and wrote the Master's thesis under supervision of well-known Prof. A. For many reasons that I don't want to list here, I plagiarized. The first part of my thesis was background, and the second part was the original contribution.

In the background part, I copied an entire chapter from textbook T about algorithm S. Algorithm S was invented more than 50 years ago, and is described in several books, including the very well-known T. I didn't paraphrase at all, I started by citing T, and then copied the whole chapter word by word.

The contribution part is actually contribution. One year after I left the school, Prof. A found another student to extend it and published the extension with me as the second author. (The paper included the algorithm and experiment in my thesis, but I didn't write a single word of the paper.)

I have moved to university Y to do a PhD. I have published several papers in top conferences and have very good relationship with several well-known researchers. I want to advance in academia.

Will the Master's thesis destroy any possibility of a future academic career? If someone read my Master's thesis, it is very easy to recognize, since the part from the textbook is in perfect English, and the rest is in extremely poor English.

Can I contact the university to submit a revised Master's thesis which re-describes the algorithm S? This is the last thing I want to do.

    +1 for a honest question, we all make mistakes, now what. Disarming the latent bomb seems to be the right thing to do, asking university X how to proceed (with caution). Now, how hard can redescribing a well-known algorithm be ? (especially if you want to teach in the future) Jun 22, 2014 at 11:42

    If you go to the university and tell them, nobody will be thrilled about it, but they will also be invested in keeping the matter silent. Accepting plagiarized text as a graduate thesis does not reflect well on an institution. So don't be afraid that they will start a public scandal. Personally, I also think that they should let you re-defend your title, because this is the long-term winning strategy when it comes to human mistakes, but I can't promise you that the staff will see it that way.

    Congratulations for recognizing that you made a mistake, and your willingness to make amends. The "road to redemption" may be rough, very rough even - but RESTORING YOUR INTEGRITY IS SO IMPORTANT, that even if it means re-writing, submitting, defending your thesis to get a degree you deserve, you should go through with it. Do try to get some professional advice - is there an ombuds person at your old university that you could contact (or maybe "a friend" could contact) to get a sense for how they might react?

    I just stumbled upon this question. Would you mind sharing what you did and how it worked out?

    Wait a minute. Am I the only one who doesn't think this is as big of a deal as it is being made out to be? You essentially reproduced a section from a prior publication, but it was in your background section, where the material is understood to be non-original. Furthermore, you say that you cited the source. It isn't as if you took someone else's work and claimed that it was your own. I guess this would fall somewhere along the lines of "unauthorized reproduction", then?

I cannot tell you what the university will do if you confess; I am not employed in a position which would be involved in such a decision, and besides, I think that this will depend on cultural and legal factors, plus the personality of the decision makers in your case.

But I still think that it is better if you confess. There are several reasons for it:

  1. Your own inner peace. By contemplating confession and posting here you show that you have matured and have higher integrity and a better understanding of academic rules and the seriousness of plagiarism than back when you submitted your thesis. If you don't confess, you will have to live with both 1)the guilt of not only having made the mistake once, but still actively deceiving people, and 2) the anxiety of being discovered someday. I have been on both sides of a "hidden guilt" situation (although when it was on academic matters, it concerned milder cases), and I can tell you from experience that it is a bad situation, especially for the person who feels guilty and dreads discovery. It burdens you with a stress which can permeate to many unrelated areas of your life and make you miserable.

  2. Your risk of discovery rises with time. Nowadays, universities start to routinely employ plagiarism software. Who knows what funky electronic agent will snuffle in your old thesis ten years from now? Twenty? What if such software becomes so ubiquitous and cheap that employers start running it on your old theses when you apply for a job?

  3. If you confess, you will suffer negative consequences - but not nearly as bad as if you are discovered by a third party. Confession, especially if you are repentant, shows that you are capable of feeling remorse, have high integrity, also courage, and are willing to take responsibility. Being caught makes people see you as a cold-blooded fraud not deterred by social emotions like guilt and remorse. This makes you dangerous to them and reduces their empathy for you. They are much more likely to be lenient if you confess than if you are caught by others.

  4. The later it comes out, the worse for you. If you are either caught, or confess yourself much later (e.g. because you notice the negative effects of guilt and anxiety - and yes, this happens, I have witnessed such late confessions), it will have negative effects on your career. But right now, you are at its beginning.

    • You have relatively little to lose yet. If you wait until later, you will have much more to restore after such a reputation blow.
    • The younger you are when it happens, the more time you have to build a solid career without having to start anew. At times when you advance into more leading positions, it would be better that this story is a thing of the past, forgotten by most, than that it hits you out of nowhere.
    • The sooner you confess after the mistake, the less reputation you lose. The less time you carry the problem hidden around, the less callous you appear, and also people feel less deceived.
    • Once it comes out, everybody who has relied on your thesis being correct will be miffed. The more your life progresses, the more this number of people grows. If you confess early, you limit this number.
  5. Your university is not interested in a public scandal. The dean doesn't want to open the morning paper and see a "university duped by brazen plagiarist" title. They will be unpleasantly surprised by a private confession too, but they will not feel that the situation is out of their control, or that the worst that can happen has already happened. They will have some incentive to cooperate with you, as long as you confess. If you are caught, their best strategy becomes to distance themselves from you and denounce you.

  6. Time has shown that redemption is more beneficial to society than punishment-as-deterrent. This has been repeatedly shown in many situations: religious context (most of the New Testament is based on it, even though many Christian churches have historically been on the side of harsh punishment), law enforcement (prisons which are pleasant for the prisoners show better reformation rates) and parenting. So many people who have advanced to leadership positions have the wisdom not to mete out severe punishment for misconduct. Especially if you indicate that you are unlikely to repeat the mistake (and a confession is a very important part of it), they can be lenient. There is no guarantee that the leaders of your university will share this belief, but it is not exceptionally rare either.

They will still have to enforce some consequences. It would be both unfair to the students who played by the rules to get their degree, and damaging to the university's reputation to just let you have your degree when you did not follow all requirements for it. But they will not be vengeful, seeking to end your career. This is something which certainly happens when academic misconduct is caught much later by a third party after the fact, see the German examples Peter Jansson cites (and notice that in some cases for the German politicians, their plagiarism was limited to a few sentences), but also cases like this one in which a renowned professor's academic career came to an end after academic misconduct (although not plagiarism) was proven.

You may want to find support before you go straight to the people who have the most to lose from the news. The behavior of your current employer is also hard to predict (they might be legally required to terminate you if a Master's degree was required for your acceptance into the Ph.D. program), but if you think they will be on your side, you might want to talk to them first so, when you come to the university, you have somebody who can testify that your current level of work is as good as one of a person who obtained a Master's degree regularly. Especially if you have coauthored with somebody with a good standing in your community, they may be interested in helping you rather than having a publication in coauthorship with somebody whose reputation was destroyed (but gauge them as a person too, some people will prefer to just drop you and forget you).

I hope everything turns out to the best for you. As Nikana Reklawyks said, we are all human and make mistakes. If you are willing to repair the damage yours caused, this makes you a better, not a worse, human being.

    "If you confess, you will suffer negative consequences - but not nearly as bad as if you are discovered by a third party." This is the most important part. You may be able to "weather the storm" if you confess your actions. If someone makes an accusation, it will be a lot harder to sweep it under the rug.

Plagiarism is plagiarism and your existing thesis is the one which got you your degree. Since you have received your degree, the possibility is to confess to the plagiarism resulting in, possibly retraction of the thesis and removal of the degree. There have been a few highly publicized cases of plagiarism of PhD theses by people who have come to hold high positions in society (Example one and two). The exposure of these cases have led to them losing both their position and their degree. Having plagiarized your way to the degree could easily backfire at any time if, as you say, someone finds out. Now, we all make mistakes in life so I would think the best way to act responsibly is to contact a lawyer or the legal department of the university to discuss the matter and a way forward.

Regarding your publication, it seems as if it would not be affected by the story since it is your original work that has been published and I doubt that the authors copied the plagiarized chapter into the paper.


I realize that I may be late in seeing this and answering this, but I believe confessing is the way to go. I am a university administrator who has handled cases of plagiarism. In some cases, the plagiarism was discovered years after the student had received the degree. On discovery of plagiarism, the matter generally goes to a disciplinary committee. For academic misconduct, disciplinary committees look for remorse on the part of the student in considering penalties. In instances where sufficient remorse is shown, students are given the chance to revise their thesis instead of depriving them of their degree. In your situation, the revision is not difficult because it is in the "review of literature" part rather than the "innovation" part. There is no issue of whether the revised work will be degree-worthy, which makes it easier on the examiners who will have to review and approve the revised thesis.

    It's awesome to have a person in your position contribute in this level of detail. Is it possible for you to comment on how common your policies are? Do you know how likely it might be to find similar policies at other institutions?

Edited completely, given correct comments below stating that I seemed to be advocating non-confession.

I think the comment above both understates the case re punishment - you likely would lose your degree and your place on the PhD programme and admiration for your confession won't count for much - and overstates your likelihood of being caught. Universities archive dissertations for x years then pulp them.

What is strong is this: you lied, the weight of that won't make for a comfortable career and you deserve a consequence, at least on the facts as presented.

In short, should you confess, be prepared for another career.

Apologies for coming across like I don't take the ethical issues seriously. My intent, very badly put, was rather to prepare you for the worst if you come clean.

  • I think this and most answers miss an important detail: He DID cite the source of the text. Doesn't that make it NOT plagiarism?

  • No. It is plagiarism. Citation is not enough: if you are using someone else's words you indicate appropriately by placing the quote in quotation marks and/or blocking the text margins. UK institutions use something like "using the work of others as if it's the writer's own' or some such formulation. So in this case if the student had started the chapter with: this chapter in its entirety is paper x then maybe it would simply be atrocious scholarship and not an academic offence.

    OK, I grant that it certainly should have been different, but perhaps OP can clarify whether it was intentional or inadvertent formatting error. He did say his English was terrible at the time.

  • @WGroleau Yeah: that is an issue. For what it's worth my stance is that it's a separate one though. That is, whether work is plagiarised is a technical question. My judgement on the student's reported state of mind at the time might come into the question of consequences. But I recognise that this isn't the only possible view on the matter.
