Could you spot an AI-written book?
Writer Vauhini Vara conducted an experiment to test whether people could distinguish between her own writing and AI-generated text mimicking her style. She found that even close friends and longtime writing peers could not reliably tell the difference. The results suggest AI writing has become increasingly indistinguishable from human-authored work, especially in short passages.
- ▪Vauhini Vara had an AI model trained on her previous books and journalism to generate sample passages in her style.
- ▪She compared AI-generated text with her own writing and sent them to people who know her work well, including her best friend and writer friends.
- ▪None of the recipients could accurately identify which passages were written by her and which were generated by AI.
- ▪One passage praised for its clarity and emotional resonance was revealed to be AI-generated, not human-written.
- ▪The experiment highlights how advanced AI has become in mimicking individual author voices, blurring the line between human and machine writing.
