Artificial intelligence can predict your personality by scanning your eyes

"The eyes are the window of the soul." Unless you're a state-of-the-art set of machine-learning algorithms with the ability to demonstrate links between eye movements and four of the big five personality traits. If that's the case, then Cicero was spot on. A joint project between the University of South Australia and the University of Stuttgart had an artificial intelligence track and monitor the eye movements of 42 human participants using a video-based eye-tracker from SensorMotoric Instruments. Of the "big five" personality traits (openness, conscientiousness, extraversion, agreeableness and neuroticism), the artificial intelligence was able to reliably identify four: neuroticism, extraversion, agreeableness and conscientiousness.
