Most people would say, if asked directly, that they know the difference between something they can control and something they can’t. Two studies, one a classic experiment on pure chance, one a large clinical meta-analysis, suggest that distinction is a lot blurrier in practice, and that both chasing control where none exists and learning to release it where it genuinely doesn’t have real, measurable effects.
The clearest evidence comes from a 1975 study by Ellen Langer, published in the Journal of Personality and Social Psychology, which coined the term “illusion of control” through a series of experiments built around pure chance. In one, office workers took part in a football lottery. Some were simply handed a ticket at random, others were allowed to choose their own ticket from a set of identical options. Later, when offered the chance to sell their ticket back before the drawing, people who had picked their own ticket demanded a mean price of $8.67, more than four times the $1.96 asked by people who’d been handed one, despite both groups having exactly the same odds of winning. In a separate experiment, people playing a pure chance card-cutting game bet significantly more money when facing a nervous, awkward opponent than a poised, confident one, as though the other person’s demeanor could somehow influence a coin-flip-style outcome it had no actual power over. In both cases, people were behaving as though skill or agency were involved in something that was, mathematically, pure luck.
A second study helps show what happens when people are taught to do the opposite, to consciously accept what genuinely can’t be controlled rather than fight it. In a 2015 meta-analysis by Jaap A-Tjak and colleagues, published in Psychotherapy and Psychosomatics, the researchers statistically combined 39 randomized controlled trials covering 1,821 patients, evaluating Acceptance and Commitment Therapy, a treatment approach built specifically around accepting difficult thoughts and circumstances rather than struggling to control them. ACT significantly outperformed waitlist controls, psychological placebos, and standard treatment-as-usual across a range of conditions including anxiety, depression, addiction, and chronic physical health problems. It also meaningfully improved patients’ quality of life and life satisfaction. Perhaps most notably, ACT performed statistically indistinguishably from Cognitive Behavioral Therapy, one of the most established, control-oriented treatment approaches in clinical psychology, suggesting that deliberately letting go of the struggle for control can work just as well as trying to manage it directly.
Together, these two studies point to control as something people both overestimate and, with the right approach, can learn to release without losing ground. Langer’s research shows how easily an illusion of control creeps into situations with no real control to be had, inflating how much value or confidence people attach to pure chance the moment choice or personality gets involved. A-Tjak and colleagues’ research shows that consciously loosening that grip, specifically training people to accept what’s genuinely outside their control, produces real clinical improvement on par with therapies built around managing and controlling symptoms directly. Between the two, the instinct to control looks less like a rational response to the world and more like a default setting, one that can misfire in low-stakes settings like a lottery ticket, and one that, when consciously released, can meaningfully ease real psychological suffering.
It’s worth being honest about what these two studies don’t establish. Langer’s experiments, foundational as they are, involved relatively small samples in specific lab settings from the 1970s, and while the illusion of control effect has been widely replicated since, the exact dollar figures reflect that particular context rather than a universal constant. A-Tjak and colleagues’ meta-analysis draws from trials that varied in quality and specific conditions treated, and while ACT’s overall effectiveness is well-supported, it isn’t uniformly superior to every alternative treatment for every condition studied.
Within those honest limits, the research offers a genuinely clarifying pair of lessons. Control is worth pursuing where it’s real, and worth naming as an illusion where it isn’t, the chosen lottery ticket was never actually more likely to win. Learning to consciously release the grip on what was never controllable in the first place isn’t resignation, the clinical evidence suggests it’s closer to a specific, teachable skill with measurable psychological benefits of its own.
