Artificial intelligence can do more than change what people see in a photograph. New research suggests it may also influence what people remember.
A study from researchers at the Massachusetts Institute of Technology’s Media Lab, reported by The Washington Post, found that people who viewed AI-altered photographs were more likely to recall details that were not in the original images. Participants also expressed greater confidence in some of those false memories.
The findings raise questions about how AI-generated and manipulated images could affect people’s memories, particularly as realistic digital images become easier to create and share.
Researchers showed 200 participants 24 photographs depicting everyday scenes, including a wedding, a city street and a race. After a break, participants were shown either the original images, AI-edited photographs, AI-generated videos or videos based on AI-edited images.
The researchers then tested what participants remembered about the original photographs.
The results showed that exposure to altered visuals increased false recollections. The strongest effect occurred among participants who watched AI-generated videos based on edited photographs, who had more than twice the rate of false memories as the control group. They were also more confident in those inaccurate recollections.
The findings highlight a potential problem as AI tools make it easier to create realistic images and videos that depict events differently from how they actually happened.
For example, someone looking at a family vacation photo might later see an edited version featuring an added dog, a more dramatic sunset or a bird in the sky. Researchers warn that seeing those added details could influence how that person remembers the original experience.
The concern extends beyond personal photographs. Altered images and videos could also affect how people remember public events, interpret evidence or recount experiences to others.
The research does not mean every edited photograph will create a false memory, but it suggests that visual information can influence recollection even when people feel certain about what they remember.
Researchers say the findings are a reminder that human memory is not a perfect recording of the past. People can unintentionally incorporate new information into their recollections, and AI-generated visuals may make that process more complicated.
As AI-generated images and videos become more realistic, distinguishing between what someone actually experienced and what they saw later could become increasingly important.
The takeaway: A photograph may feel like proof of a memory, but it is worth checking the original image and its source before assuming every detail is real.
