In a study recently published in the journal Patterns, researchers demonstrate that computer algorithms often used to identify AI-generated text frequently falsely label articles written by non-native language speakers as being created by artificial intelligence. The researchers warn that the unreliable performance of these AI text-detection programs could adversely affect many individuals, including students and job applicants.
According to the article grammatical errors are not the reason. The reason is that AI uses simpler vocabulary to mimic a regular conversation of average people.
