In February 2007 the Supreme Courtroom heard a case that hinged on about quarter-hour of video proof from two police automobiles’ dashboard cameras: footage confirmed the entrance finish of a police automobile because it pursued a driver in Georgia earlier than it rammed into the again of the motive force’s automobile, which subsequently crashed. The motive force, 19-year-old Victor Harris, was left completely paralyzed by the incident.
Harris sued the officer who hit his automobile. He alleged that the officer, Timothy Scott, had used extreme drive. Earlier than the Supreme Courtroom thought-about the case, decrease courtroom judges had already reviewed the video footage and located in Harris’s favor, with one writing that Harris had introduced little risk to the general public regardless of his dashing.
However the Supreme Courtroom disagreed, issuing an 8–1 determination in favor of the police officer. Within the majority opinion, the justices decided that Harris posed an “precise and imminent risk” to the general public and wrote that “we’re comfortable to permit the videotape to talk for itself.”

The courts had reviewed the identical video. However they got here to dramatically totally different conclusions about what it confirmed. Certainly, the Supreme Courtroom’s 9 justices weren’t all aligned on what they noticed within the footage; in a dissent, the late justice John Paul Stevens wrote that the video “confirms, reasonably than contradicts” the decrease courts’ determination in favor of Harris. The episode raises the query: How can totally different individuals watch the identical video but see such vastly various things?
“Seeing isn’t just what our eyes bodily see,” says Sandra Ristovska, an affiliate professor of media research on the College of Colorado Boulder, “but additionally the experiences and concepts that viewers deliver to pictures.”
Within the years since Scott v. Harris, the case has change into a quintessential instance of this phenomenon and has been studied by authorized students and psychologists alike. “Video is in every single place, from our telephones to surveillance cameras on metropolis streets. And it has change into a significant type of proof in courtroom,” Ristovska says. And understanding how it may be interpreted otherwise relying on who sees it’s crucial to making sure justice is pretty utilized, she says.
How your mind adjustments what you see
One confounding consider how somebody views a video is one thing psychologists have dubbed “slow-motion bias.” In one 2016 examine, researchers confirmed that when viewers watched surveillance footage of a capturing in sluggish movement, they perceived the shooter as “extra intentional.”
Equally, if a video is shaky, viewers can interpret occasions as extra intense.
Then there may be the “digital camera perspective bias,” says Neal Feigenson, a regulation professor at Quinnipiac College. In a sequence of research at Ohio College, contributors seen movies of individuals confessing to crimes. In some movies, the digital camera targeted on a suspect’s face, whereas in others, it targeted on the interrogators. Viewers who noticed movies centered on the suspects’ face have been extra more likely to understand the confessions as “extra voluntary.”
Eyewitness accounts will also be contaminated after the actual fact. When you and a good friend witness a automobile accident, as an illustration, after which discuss it, you may unwittingly undertake a few of your good friend’s reminiscences as your individual. This phenomenon is named reminiscence contamination, says Miko Wilford, an affiliate professor on the division of psychology at Iowa State College.
An identical impact may occur if eyewitnesses are requested to remember an incident that additionally they noticed on video, she says.
“We’re simply very dangerous at recalling the origin of knowledge in our reminiscence,” Wilford says.
When somebody retrieves a reminiscence, they “aren’t enjoying a recording again,” explains Elizabeth Loftus, a psychology professor on the College of California, Irvine. Reasonably “we’re developing” that reminiscence, she says. In different phrases, the mind collects bits and items of knowledge, typically from totally different instances and locations, and forges them right into a reminiscence. “As soon as that occurs, it’s not straightforward to separate out what piece got here from the place,” Loftus provides.
In 2016 Loftus and her colleagues printed a paper arguing that cops ought to write down their account of an incident earlier than viewing physique digital camera footage: if officers watch such a video first, that may strengthen their reminiscences of the small print proven in it—however weaken their skill to recall different info that was not captured within the recording.
People are particularly attuned to visible info. Extra of the processing energy of the mind’s prefrontal cortex is devoted to visible info than audio info, Ristovska notes.
That helps clarify why individuals usually belief video proof—even after they know it’s false. In a notable 2008 examine on this impact, researchers requested college students to carry out a playing process on a pc. When the scholars have been falsely accused of dishonest and proven a pretend video of the alleged infraction, the “overwhelming majority” of the scholars confessed “with out resistance,” the researchers discovered.
“Folks intuitively are likely to imagine that video offers them the target actuality of what it depicts,” Feigenson says. “That is naive realism.”
How bias can have an effect on a viewer
Cognitive biases may have an effect on our interpretations of a video. Take, for instance, “selective consideration”: if prompted to give attention to a particular side of a video, viewers may miss different necessary particulars, Ristovska says. Folks will also be primed to see what others need. In 2024 analysis by Feigenson and his colleagues confirmed that an legal professional’s description of a video may colour jurors’ perceptions of the particular footage.
An individual’s beliefs may form their visible notion. Individuals who establish with regulation enforcement, as an illustration, usually tend to understand cops as performing lawfully in video proof than individuals who don’t establish with regulation enforcement are, Ristovska says. An individual’s opinions on different probably divisive matters similar to abortion, the army or the dying penalty may have an effect on how they view video proof.
In 2009, when researchers polled 1,350 People concerning the video on the middle of Scott v. Harris, most agreed with the Supreme Courtroom’s majority view. However the researchers recognized “sharp variations of opinion” alongside cultural and ideological strains, together with race, revenue and an individual’s views on societal hierarchy. To Ristovska, the analysis reveals that “seeing is believing” finally relies on who’s doing the seeing.
Ideology may assist clarify why totally different individuals may view the video proof of the current killing of Renée Good, a lady in Minnesota, by an Immigrations and Customs Enforcement (ICE) officer in such distinct methods, says Loftus, who has studied human reminiscence and the regulation for many years. “Folks [have] preexisting biases that both ICE is nice or ICE is dangerous,” she says, “and which will have an effect on how they understand the habits that they’re taking a look at.”
Ought to we modify how we take a look at movies?
To assist handle the issues that may come up when totally different individuals interpret video proof otherwise, Ristovska says viewers ought to decelerate and “interact with this materials extra thoughtfully.”
And Feigenson recommends viewers acknowledge that “different affordable individuals could moderately see issues otherwise,” including that “this may also help mood the overconfidence in video proof that naive realism tends to engender.”
Including artificially generated movies into the combination solely complicates issues. In 2025 Loftus, in collaboration together with her colleagues on the Massachusetts Institute of Know-how Media Lab, printed a paper that demonstrated how synthetic intelligence can change individuals’s reminiscence of a picture.
Members have been proven totally different pictures, together with {a photograph} of a person and a lady who weren’t smiling. The contributors have been then proven the pictures once more, besides this time the images had been barely doctored utilizing AI. Within the case of the one depicting a person and a lady, the researchers tweaked the picture to stick grins on them. When proven the unique picture with the girl’s face obscured, individuals subsequently falsely remembered her smiling.
The concept of AI-introduced false reminiscences is “regarding,” says Pat Pataranutaporn, an assistant professor on the MIT Media Lab and a co-author on the examine. However he hopes the findings may have constructive implications, too. If individuals have traumatic reminiscences, for instance, “AI may assist them misremember in a extra constructive method,” he says.
