Scientists have used an AI similar to ChatGPT to passively decode human thoughts with an accuracy of up to 82%, an astonishingly high level of precision.
The breakthrough paves the way for potential applications in neuroscience, communication, and human-machine interfaces.
This advancement raises concerns regarding mental privacy and highlights the need for policies that protect individuals from potential misuse as this technology progresses.

The GPT model generated intelligible word sequences from perceived speech, imagined speech, and even silent videos with remarkable accuracy:
-
Perceived speech (subjects listened to a recording): 72–82% decoding accuracy.
-
Imagined speech (subjects mentally narrated a one-minute story): 41–74% accuracy.
-
Silent movies (subjects watched Pixar film clips without sound): 21–45% accuracy in decoding the subject’s interpretation of the film.
„It is crucial to raise awareness about the risks of brain-decoding technology and to enact policies that protect every person’s mental privacy.“
