We’re told that AI deepfakes are becoming so good that the human eye won't be able to tell what's real. While technical detectors are failing, this paper shows that a simple 'psychological inoculation' works. By warning people about manipulation and showing them deliberately 'bad' deepfakes, you can train the brain to spot the real ones later. It’s like a medical vaccine: a small dose of the threat builds up your mental immune system. It means the best defense against high-tech deception isn't more tech—it’s just better cognitive training.
From the abstract
Despite growing interest in countering the threat of deepfake misinformation, most interventions aimed at enhancing human detection have thus far proven unsuccessful. In the current study we explore the potential of a popular psychological intervention: cognitive inoculation—which to our knowledge—has not been tested in the context of deepfakes. In a pre-registered between-subjects experiment (N = 297), we evaluate whether an inoculation-based video intervention improves people’s deepfake detect
