What happens when you strip away someone’s identity, place them in a darkened room, and tell them not to speak? The immersive theatrical experience Sleep No More—a long-running, mask-filled adaptation of Macbeth—serves as a living laboratory for this very question, echoing some of the most famous and controversial psychology experiments in history.

The show deliberately dismantles every convention of traditional theater. Audience members surrender their phones, don anonymous Venetian masks, and wander silently through a six-floor set where performers act out wordless, often violent or sensual scenes. The creators designed this environment to provoke a sense of mystery and slight threat, knowing that the darkness and rules force people out of their comfort zones. The mask, in particular, becomes a powerful tool for transformation, emboldening some patrons to get unusually close to performers, touch props, or even interfere with the action—behaviors they would never consider in their daily lives.

This experiment in anonymity and situational power naturally brings to mind Philip Zimbardo’s Stanford Prison Experiment, where college students assigned roles as “guards” or “prisoners” quickly adopted abusive and submissive behaviors. The podcast draws a direct parallel, suggesting that Sleep No More places its audience in a similarly constructed, role-altering situation every night. However, the episode also delves into the substantial controversy surrounding Zimbardo’s work, citing later revelations that participants were coached or performed for the researchers, challenging the experiment’s conclusion that people are purely products of their situation.

Despite the potential for chaos, the most common outcome within Sleep No More is not anarchy but a leaning toward empathy and protection. Instances of audience members offering a towel to a vulnerable performer or trying to save a character from poison are frequently reported. This suggests that even when anonymous and unfettered, most people’s inherent social conditioning toward goodness prevails. The experience ultimately becomes a testament to the strength of social mores, showing that when given the freedom to choose, people often default to cooperation and care rather than cruelty.

Surprising Insights

• The show’s creators found that for the immersive experience to work, the environment needed to feel less safe. When fire regulations forced them to brighten the lighting in an early version, the audience felt too comfortable, treated the space like a museum, and chatted—completely breaking the intended spell.
• The anonymous mask didn’t just encourage minor mischief; in extreme cases, it led to outright confrontation, such as one audience member violently throwing objects at a performer behind glass, an act she later claimed was driven by the mantra “fortune favors the bold.”
• While the Stanford Prison Experiment is a cornerstone of psychology textbooks, economist Steve Levitt and others express deep skepticism, arguing that the participants’ behavior was likely influenced by their desire to fulfill the researcher’s expectations rather than by the situation alone.
• The most stolen items from the elaborate set weren’t small trinkets, but character-driven props like Lady Macbeth’s letters or Macbeth’s coat, suggesting audiences craved a tangible, personal connection to the narrative.

Practical Takeaways

• Embrace Anonymity for Honest Reflection: When placed in a situation where you feel anonymous (even digitally), observe your impulses. It can reveal hidden aspects of your behavior, from boldness to voyeurism, offering a mirror to your less-socially-governed self.
• Question the “Situation”: Be mindful of how your environment and assigned role—be it at work, in a family, or online—are shaping your actions. Recognizing this influence is the first step toward ensuring your behavior aligns with your actual values.
• Lean Into Disorientation: If you want to spark creativity or new perspectives, deliberately place yourself in unfamiliar, slightly uncomfortable contexts where the rules aren’t clear. Like the darkened halls of the show, these spaces can force new patterns of thinking.
• Trust in Social Conditioning: The fact that chaos doesn’t erupt in a rule-free, anonymous space like Sleep No More is a reminder that society’s inculcation of norms is powerfully effective. You can generally have faith in the intrinsic goodwill of others, even when oversight is minimal.
