AI Can Predict four of the "Big Five" Personality Traits Using Only Eye-movement Tracking Data Asgardia Space News

Many say eyes are a window into the soul and now an emerging body of research suggests that the way in which we move our eyes is affected by our personality. Studies on this topic have found people with similar traits tend to move their eyes in similar ways. For instance, optimists spend less time looking at negative emotional stimuli, such as images of cancer, while curious people tend to take in all areas of a scene. Now, an international team of researchers from institutions in Australia and Germany decided to understand more about the connection between personality and eye movements by developing a machine learning algorithm, a kind of computer code which learns without the need to be specifically programmed, as reported by New Scientist. For this new study, published in the journal Frontiers in Human Neuroscience, the researchers gave 42 students at Flinders University in south Australia special eye-tracking glasses.
