About this episode

A college professor just exposed one of the biggest problems schools are facing in the age of artificial intelligence: students using AI to cheat without even reading what it gives them. In this story, Alcorn State University history professor Dr. Jason Gibson reportedly embedded hidden white text inside a midterm prompt. The students couldn't see it, but AI chatbots could. That hidden instruction told the AI to include bizarre references to Madagascar in the answer — and when dozens of students submitted responses mentioning Madagascar, the trap worked. This wasn't a complicated AI detector, expensive software, or a high-tech investigation. It was a simple test of whether students were actually doing the work or blindly copying and pasting into ChatGPT. According to reports, 32 out of 35 students were caught, raising serious questions about academic honesty, how schools should adapt, and whether traditional assignments still make sense in the AI era. In this video, we break down what happened, why the professor's trap worked, and what this story says about the future of education, cheating, and AI in the classroom.
