The New Stanford Prison Experiment, an unscripted Netflix series, moves one of psychology’s most disputed studies out of a university basement and into a real prison. Thirty volunteers are assigned at random to wear a guard’s uniform or a prisoner’s, actual inmates are present in the building, and the cameras never switch off. The question is the old one: what a uniform does to the person inside it.

The series takes the question Philip Zimbardo’s study made famous and asks it again: does assigned power change ordinary people? The answer that study gave became a textbook staple. The way it reached that answer has been picked apart for decades, most sharply in recent years, and that history is the real context for this premiere. Executive producer Jane Lipsitz, of the production company Alfred Street Industries, does not pretend otherwise. “When the show was first announced, there was a lot of outrage that anyone would even attempt the Stanford Prison Experiment again,” she told Netflix’s Tudum, “and given what happened with the original, I completely understand that reaction.”

Her defense is a list of differences. “If we were simply recreating the original experiment, that would be unconscionable,” Lipsitz said. “But this is a different time, with different participants, different safeguards and, ultimately, a very different journey.” Her team spent more than a year developing the series before a single participant walked in.

What the original study actually was

The facts of the first version are smaller than its reputation. In August 1971, twenty-four male college students answered a newspaper advertisement offering fifteen dollars a day for a “psychological study of prison life.” They were split at random, and the prisoners were arrested by real Palo Alto police before being taken to a mock jail built in a stretch of basement corridor in Jordan Hall, Stanford’s psychology building, closed off by two fabricated walls. Zimbardo cast himself as superintendent. The study was planned to run up to two weeks. It stopped on the sixth day, after the psychologist Christina Maslach confronted him about what she had seen.

What followed was a slow erosion. As early as 1975, researchers argued that the guards were playing the roles they assumed the experimenters wanted. Recordings that circulated widely in 2017 captured the study’s warden, an undergraduate assistant named David Jaffe, pressing a guard to be tougher. In 2018 the French researcher Thibault Le Texier published Histoire d’un mensonge, a book-length case that the guards had been told how to behave. Most of the guards have since said they were acting. Zimbardo, who died in 2024, rejected those critiques as attacks that ignored the data.

A real prison, a mixed cast and a safe word

Read as design, the changes are the story. The original recruited only male students. The new cast mixes women and men and was chosen, Netflix says, to vary by geography, political belief, income and life experience. Lipsitz calls the inclusion of women essential, given the current argument about gender and power, and describes the wider casting net as fundamental to the experiment’s legitimacy.

The set changed too. A basement can be dismantled when the study ends; a prison cannot. “A real prison carries a history, an energy and a sense of confinement that you simply can’t recreate on a set,” Lipsitz said. The presence of actual inmates, in her words, served as “a constant reminder that, outside the experiment, these roles and power dynamics have very real consequences.”

Then come the safeguards the original lacked. Every participant went through psychological screening before entering and signed up on informed terms. “Everyone had a safe word they could use to opt out at any time, and psychologists were available 24/7 for support,” Lipsitz said. Those psychologists also monitored the experiment continuously, she added, “so we could intervene if there were ever concerns about a participant’s well-being.”

The camera is the variable nobody can remove

The most telling decision is a visual one. To keep the crew out of the experiment, production contact was held to what Tudum calls an “absolute minimum,” with robotic cameras installed inside the prison, and interviews were set up so participants could not see who was asking the questions. The idea is to erase the observer. The next detail Netflix offers quietly undoes it: the participants started talking straight into the cameras.

That is the knot at the center of the project. The sharpest criticism of the original concerned the watcher, students who knew they were observed and played to what they believed the observer wanted. When the BBC staged its own prison study in 2002 with the psychologists Alex Haslam and Steve Reicher, Zimbardo dismissed it as a reality show for exactly that reason. Lipsitz takes the same comparison and embraces it. The Stanford study, she argues, “was the forebear of the social experiments that unscripted television is based on.” Her summary of the format could double as the protocol: “Place real people into a complicated and constructed environment, and document what happens.”

Three experts frame what those cameras record. Alison Wood Brooks, a behavioral psychologist at Harvard, helped the team think through the psychology and keep the experiment inside its ethical guardrails. Trymaine Lee, a Pulitzer Prize-winning journalist whose reporting has run from Hurricane Katrina to the justice system, brings the outsider’s eye. Michael Cantrell, a retired federal corrections professional with close to thirty years of experience, supplies what Lipsitz calls “the real-world prison perspective.” She says she valued that “the three of them didn’t always see things the same way.”

From Das Experiment to Netflix’s own jail

The lineage is long and mostly fictional. Oliver Hirschbiegel’s Das Experiment turned the premise into a German thriller. Paul T. Scheuring remade it in English as The Experiment, with Adrien Brody and Forest Whitaker. Kyle Patrick Alvarez dramatized the Stanford study itself with Billy Crudup as Zimbardo. The BBC version is the closest ancestor in form, and its findings pointed somewhere less fatalistic: people did not slip mindlessly into roles, and leadership mattered more than costume. Netflix has already worked this ground once, with Unlocked: A Jail Experiment, a reality series set inside a working jail.

Netflix’s logline frames the stakes as an open bet. Participants, it says, will “discover whether ordinary people inevitably conform to the roles they’re given,” or whether empathy, morality and individuality can hold against the pressure. Lipsitz adds only a teaser: “What we discovered during this process was something we never saw coming.” That line carries the commercial premise. A return to a discredited study justifies itself only if the outcome differs, and the series has promised a different journey without saying which way it went.

The critics who called the project indefensible, Nerdist among them, are answering a question about ethics. The series is answering one about television, and about whether the oldest premise in unscripted entertainment still holds half a century after the first version was shut down on its sixth day.

Nothing in the safeguards resolves the original problem, and nothing could. Thirty people who agreed to be filmed, who can see the lenses and who signed up under the experiment’s name, will do things to one another that viewers will read as evidence about power. Whether it is evidence about power, or about how people behave once they know they are part of a famous story, is something the format itself cannot settle.

Release date, episodes and where to watch

The New Stanford Prison Experiment premieres on Netflix on Wednesday, October 21, 2026, with all six episodes, each running about 45 minutes. It is produced by Alfred Street Industries, with Jane Lipsitz, Dan Cutforth, Nan Strait, Dan Volpe, Jeff Grogan and Mike Odair as executive producers. Lipsitz and Cutforth previously founded Magical Elves, the company behind Top Chef and Project Runway.

Is The New Stanford Prison Experiment scripted? No. It is an unscripted reality series. The participants are volunteers, not actors, randomly assigned as guards or prisoners for two weeks.

Is it the original Stanford Prison Experiment? No. It is a new experiment with thirty participants of different genders, staged in a real prison instead of the mock jail built in a Stanford basement in 1971.
