A success for tech and a threat for societies and democracies — deepfakes have become so realistic that they are indistinguishable from real faces and even appear more trustworthy to us
In a new success story for the tech industry and an alarming threat for societies and democracies, deepfakes have become so realistic that they are indistinguishable from real faces and even appear more trustworthy to us.published in peer-reviewed journal PNS on Tuesday found that people cannot tell apart high-quality fake imagery to pictures of real people, and tend to give higher ratings of trust to the synthetic media.
They found that people were able to pick out the fakes with less than 50 percent accuracy if given no feedback and only slightly above chance with feedback.Study figure showing"the most and least accurately classified real and synthetic faces." Researchers asked 223 participants to rate people in a series of images on a scale of 1 to 7 . Some of the faces were of real people and some of computer-generated fakes.
“This may be because synthesised faces tend to look more like average faces which themselves are deemed more trustworthy,” the researchers hypothesised. Then, another 219 participants were asked to do the same but this time were given feedback about each guess along the way. This feedback slightly improved the overall accuracy to 59 percent.
For both experiments, White faces were the most difficult to classify with lower accuracy ratings, and male White faces were less accurately determined than female White faces.
