AI text detectors falsely flag essays by non-native English writers as AI-generated more often than native writers' essays.

Is it true that AI text detectors falsely flag essays by non-native English writers as AI-generated more often than native writers' essays?

Yes. A peer-reviewed commentary and a 2026 systematic review report that AI detectors falsely flag non-native English writers' text as AI-generated far more often than native writers' text (roughly 50–61% versus under 5% in the reviewed experiments). A separate audit notes detectors are unreliable and biased toward human-written output, and one Arabic-language study shows misclassification of polished human text.
