After studying psychology and linguistics at the University of Toledo, he earned his master's and doctoral degrees in experimental psychology at Princeton University. Following that, he was a post-doctoral researcher in cognitive gerontology at Duke University. He has researched and published on diverse topics in the fields of language and communication, but primarily in the areas of text and discourse processing and figurative language. This research has been funded by the National Science Foundation and the Office of Naval Research. He has been a student of German and Old English, but his progress in the latter has been hampered by a lack of native speakers to practice with.
Kreuz applied the "Page 99 Test" to his new book, Strikingly Similar: Plagiarism and Appropriation from Chaucer to Chatbots, with the following results:
Page 99 of Strikingly Similar describes an accusation by The New York Sun, on the eve of the 2004 U.S. presidential election, of plagiarism by the Democratic candidate, Senator John Kerry. The senator had published a book about global crime organizations seven years earlier, and The Sun claimed that Kerry had plagiarized a sentence from a 1993 newspaper story, and three sentences from a 1996 magazine article.Visit Roger Kreuz's website.
The newspaper’s report included the opinion of two plagiarism experts, and they disagreed about the seriousness of Kerry’s alleged appropriation. One claimed that it was a clear instance of plagiarism, while the other expressed doubts that Kerry was even the culprit, since books by politicians are often prepared by their staffs. Neither the candidate nor his staffers publicly commented on the allegations, and the claims seems not to have been investigated by other news organizations.
Readers opening Strikingly Similar to page 99 would get a good idea of what my book is about. As with many other examples I include, it illustrates how accusations of plagiarism can be wielded as a weapon against others: The New York Sun is a conservative publication, and Kerry was a liberal presidential candidate.
The passage also illustrates how even experts on plagiarism can disagree. Such judgments can be affected by how much text was copied, and by whom, and how long ago, and for what purpose. These are the same issues that judges and juries struggle with in reaching verdicts regarding claims of copyright infringement. The result has been an idiosyncratic patchwork of rulings that are not infrequently overturned on appeal.
Strikingly Similar is both a cultural history of plagiarism and appropriation and an examination of the psychological aspects of the phenomenon.
A review of appropriation across two millennia illustrates how cultural perceptions shifted between the time of the ancient Greeks and Romans, when the practice was widely condemned, and the medieval period, during which appropriation was rampant and not perceived negatively. I also describe the gradual shift to the modern view, which is inextricably bound up with notions of intellectual property, copyright infringement, and an increasingly litigious society.
At the psychological level, I assess the controversial claim that plagiarism can occur inadvertently, without conscious awareness. (Spoiler alert: several laboratory studies have concluded that this is possible, at least in some cases.) I also explore the varied motivations for why people appropriate, and why some plagiarists seem to get a pass while others are publicly condemned. And of course, generative AI has only served to muddy the waters about what counts as being truly “original” even further.
