The Golem effect is a psychological phenomenon in which low expectations placed on a person actually cause that person’s performance to decline. It’s a specific type of self-fulfilling prophecy: a manager, teacher, or other authority figure anticipates poor results from someone, and through subtle (often unconscious) changes in behavior, creates the very outcome they predicted. The concept was first described by researchers Babad, Inbar, and Rosenthal in 1982, and it has implications anywhere one person holds power over another’s development.
How the Golem Effect Works
The cycle starts with a belief. A teacher decides a student isn’t very capable, or a manager assumes a new hire lacks the skills to succeed. That belief doesn’t stay internal. It leaks out through behavior in ways the authority figure may not even notice. People who hold low expectations of someone tend to smile less at them, make less eye contact, assign them less challenging work, and respond more negatively to their contributions. These are small differences in interaction, but they are easily perceived by both children and adults.
The person on the receiving end picks up on these cues and begins to internalize them. Motivation drops. Confidence erodes. They stop volunteering ideas, take fewer risks, and put in less effort. Their performance measurably declines, which then confirms the original low expectation in the authority figure’s mind, reinforcing the cycle. What looks like evidence of someone’s limitations is often, at least in part, a product of how they’ve been treated.
The Golem Effect in Education
Classrooms are one of the most studied settings for this phenomenon. When teachers hold low expectations for students, they not only react more negatively toward those students, but the students themselves perform worse academically. John Hattie’s landmark analysis of over 800 studies found that student achievement tracks closely with teacher expectations, suggesting that what a teacher believes about a student’s ability can directly shape their results.
The mechanisms are concrete. A teacher who sees certain students as high-potential tends to choose more ambitious tasks for them, creating additional learning opportunities that other students simply miss out on. Over a semester or a school year, that gap compounds. The favored students get more practice with challenging material, more encouragement, and more chances to develop, while the rest fall further behind. The performance gap that emerges looks like a difference in ability, but it partly reflects a difference in opportunity.
One practical countermeasure used in classrooms is the “cold call” questioning strategy, where any student can be called on at any time. When all students anticipate being asked, they think and engage as a matter of routine, which prevents teachers from unconsciously directing attention only toward students they expect to succeed.
The Golem Effect at Work
In professional settings, the Golem effect plays out when managers believe certain employees lack the skills, potential, or willingness to succeed. Those employees tend to receive fewer meaningful assignments, less mentorship, and less autonomy. The consequences ripple outward: reduced self-confidence, diminished trust in peers and superiors, lower productivity, less innovative problem-solving, and a reluctance to take on responsibility. Ideas from these employees are more likely to be dismissed or ignored.
At its worst, the effect drives people out entirely. Employees who feel consistently undervalued and underestimated may leave their positions or companies, ending what has become an unsustainable situation. Organizations lose talent not because those individuals lacked ability, but because the environment never gave that ability room to develop. Meanwhile, the manager’s belief appears validated: “I knew they weren’t going to work out.”
How It Differs From the Pygmalion Effect
The Golem effect is the mirror image of the Pygmalion effect, which describes how high expectations from an authority figure improve someone’s performance. Where the Golem effect suppresses potential, the Pygmalion effect unlocks it. Managers who set high expectations and then give employees the space to meet them tend to see increased productivity, stronger commitment, better self-confidence, and more proactive behavior. Both effects operate through the same basic mechanism (expectations shaping behavior, which shapes outcomes) but push performance in opposite directions.
Research on positive expectation effects has accumulated over four decades across education, military training, and corporate settings. The Golem effect, by contrast, has been largely overlooked by researchers, partly because it’s harder to study ethically. You can’t deliberately assign low expectations to people in an experiment without risking real harm. But the phenomenon is well-documented in observational research, and its effects are just as powerful.
Breaking the Cycle
Counteracting the Golem effect requires effort from both authority figures and the individuals affected by it. For leaders, managers, and teachers, the most important first step is honest self-reflection about biases. Structured tools like anonymous 360-degree feedback, where subordinates report on the support and encouragement they receive, can surface patterns a manager wouldn’t notice on their own.
A second strategy is shifting evaluations away from vague notions of “talent” or “potential” and toward tangible elements: effort, strategies used, and observable improvement over time. When managers actively look for and acknowledge small wins that demonstrate effort and strategic thinking, they create evidence (for themselves and the employee) that effort leads to results. This disrupts the psychology of low expectations at its root.
The most direct countermeasure is deliberately applying the Pygmalion approach: consciously setting higher expectations for the people you’re tempted to write off, giving them access to challenging work, and providing the support needed to succeed. Teachers should ensure all students have opportunities to participate in challenging learning experiences regardless of prior academic performance. The same principle applies in any workplace. When you catch yourself assuming someone can’t handle a task, that assumption is worth questioning before it becomes a prophecy.
