AITA for leaving a decoy test in public to deter cheating?
In a university computer lab, a fake midterm exam sits tantalizingly on a desk, planted by an associate professor fed up with last year’s exam theft. After a student snooped through his office to steal a test, costing him 10 hours to rewrite, he’s fighting back with a decoy to teach his first-year students a lesson: cheating doesn’t pay. But his TAs cry entrapment, and Reddit’s split on whether he’s a clever educator or a petty trickster.
This story is a sharp dive into academic ethics, where a professor’s ploy sparks debate about fairness and intent. Is he teaching integrity or setting a trap? Let’s unpack this classroom caper and weigh the moral lines.

‘AITA for leaving a decoy test in public to deter cheating?’





This professor’s decoy exam is a high-stakes gamble in the battle against academic dishonesty. Last year’s theft, which led to a rewritten exam and widespread failures, clearly left a mark. A 2023 study from the Journal of Academic Ethics (sourced from Springer) found that 30% of first-year students engage in some form of cheating, often due to opportunity and pressure. The professor’s fake exam aims to exploit that opportunity to teach a lesson, but Reddit’s real_fat_hammond and others call it entrapment, arguing it unfairly tempts students.
Dr. David Rettinger, an expert on academic integrity, notes, “Proactive measures like secure exam storage are more effective than punitive traps” (sourced from Inside Higher Ed). The fake exam, covering irrelevant material (as 3mpress highlighted), risks punishing students who overhear whispers about it, not just cheaters, muddling their preparation. While the professor’s intent—to deter dishonesty—is valid, his method skirts ethical lines by manipulating rather than educating.
A better approach would be to secure exams tightly, as Jin-shei suggested, and incorporate ethics discussions into the curriculum to foster integrity. The professor could also report suspected cheaters to the university’s academic board, following protocol, as coqauvin100 advised.

Reddit split down the middle, with some cheering the professor’s cleverness and others slamming his trap as immature. From defending academic integrity to questioning his motives, the comments are a lively debate. Here’s the raw scoop:















These Redditors wrestle with the ethics of the decoy, balancing sympathy for the professor’s frustration with unease at his tactics. Do their takes hit the mark, or are they missing the bigger picture? This debate’s got everyone thinking.
This tale of a professor’s fake exam to catch cheaters sparks a thorny question: is it a brilliant lesson or a shady setup? His frustration with past theft is real, but his trap risks punishing the innocent alongside the guilty. Have you ever faced a situation where catching wrongdoers meant bending ethics?
