Strikingly Similar: Plagiarism and Appropriation from Chaucer to Chatbots by Roger Kreuz 

Core ideas

Roger Kreuz’s Strikingly Similar is a cultural and psychological history of plagiarism and related forms of appropriation, tracing them from medieval literature (e.g., Chaucer) to modern cases involving AI‑generated text and chatbots. Kreuz reframes plagiarism not merely as “theft” but as a spectrum of borrowing, adaptation, and influence that changes with norms, technology, and power. He examines why people plagiarize (from ignorance and pressure to deliberate theft), how plagiarism is detected, and how accusations of “unconscious” copying are often harder to settle than they appear.thelivinglib+2

A key theme is that originality is more fragile and socially constructed than we usually admit: the line between “inspiration” and “plagiarism” often depends on context, audience, and institutional rules rather than on any fixed number of words or motifs. Kreuz also pays close attention to how AI‑assisted writing complicates this line further, both in academic and creative settings.newyorker+1


Strengths of the book


Weak points


Why is this book relevant?

Strikingly Similar is relevant because current debates about AI, academic integrity, and “who owns an idea” are intensifying, yet most discussions are shallow or reactive. Kreuz’s historical‑psychological perspective helps shift these debates from moral panic toward more nuanced reflections about creativity, dependence on others’ work, and the evolving ethics of authorship. In an era where large‑language models can generate text that is “strikingly similar” to existing works without explicit copying, the book’s framing is especially useful for thinking about how to define, detect, and regulate borrowing.thelivinglib+2
