How much of what you believe yourself to “be” is really yours, and how much is a reflection of what others expected of you? The Pygmalion effect is one of the mechanisms that make this question so uncomfortable. It explains how expectations — those others hold about us, and those we end up making our own — can install real limits in the mind, to the point of influencing what we are able to do. That is why understanding it is a useful step for your mental reprogramming: it helps trace the origin of some of the programs we have, without noticing, allowed to be installed.
What follows is an excerpt, revised and expanded, from my book Groups and Group Dynamics.
What the Pygmalion effect is
The Pygmalion effect — also known as the Rosenthal effect — is the phenomenon by which expectations toward a person tend to influence their behavior and results, to the point of leading them to confirm exactly what was expected of them. It is, in other words, a form of self-fulfilling prophecy.
The name comes from the myth told by Ovid: Pygmalion was a sculptor who fell in love with a statue of a woman he had shaped himself, and wished so intensely for it to come to life that Venus, moved, granted his wish. The psychologist Robert Rosenthal borrowed this image to name a mechanism far more concrete than the myth: the expectations of those around us can shape us.
Rosenthal’s experiment
In the 1960s, in a California elementary school, Rosenthal and Lenore Jacobson gave the students an intelligence test. They then selected a small group of children completely at random — without regard to the test results — and told the teachers these were especially gifted pupils, bound to make rapid progress.
A year later, those randomly chosen children had clearly improved their performance, becoming among the best in the class (Rosenthal and Jacobson, 1968). Nothing magical had happened: what had changed was the way the teachers treated them.
Later research on the same effect showed what that “different treatment” consists of: toward the pupils they expect more from, teachers often have a warmer attitude, give more time to answer difficult questions, assign more demanding tasks, and notice and reinforce more often what these children do on their own (Rosenthal, 1994). More or less consciously, they create an environment that favors better learning: an environment in which their expectations end up coming true (Cooper and Good, 1983).
The weight of names: when prejudice starts earlier
Expectations, however, do not arise only from behavior. Sometimes far less is enough — even a name. A study from the University of Oldenburg, led by Professor Astrid Kaiser, gave about two thousand German elementary-school teachers an anonymous questionnaire about the reactions that certain names provoked in them.
The result was an embarrassing snobbery. Traditional names were associated by the majority with the image of the good student, disciplined and hardworking; less common names — often inspired by celebrities — triggered an immediate negative judgment in more than half of the teachers. Some pupils, in practice, risked being “failed” before they had even begun.
The delicate point is that these names are more common in less-educated or less-affluent families: so the prejudice becomes social too. And, above all, a teacher’s negative attitude weighs on the pupil’s performance — precisely in primary school, where trust would matter most, and precisely for the children who would need it most.
The halo effect: when the first judgment becomes a cage
Alongside the Pygmalion effect, another one of a similar nature is at work: the halo effect. It is the tendency to let a first impression, or a single trait, color the rest of the judgment. Together, these two mechanisms can compromise the reliability of a teacher’s judgment about a pupil’s performance.
I say this from direct experience too. In high school, my first two oral philosophy exams went badly: two low passes. Then the subject fascinated me and I began to study it seriously, until it became one of my favorites. And yet, for three years, my grade almost never rose above a bare pass. Meanwhile, some classmates comfortably reached high marks despite a far weaker preparation: they enjoyed the halo of their previous exams. In my last exam I earned a solid grade; I was examined alongside a classmate who, though she had clearly done worse, received a higher mark — and was almost scolded for not having been “as brilliant as usual.” The first judgment, by now, weighed more than the performance.
It is not just a personal impression. A study by Manchester Metropolitan University, funded by the Economic and Social Research Council, followed children aged 4-5 and the criteria by which they were assessed. It found that the first four weeks of school are crucial: in that period the teacher forms a judgment that will hardly change, even in the face of contrary evidence, and that tends to spread to colleagues as well (MacLure, Jones, Holmes, and MacRae, 2008).
This is exactly the point from which the Theory of Reality arises: not even the one who evaluates possesses an absolute reality. Their judgment, however certain, is already a filtered reality.
The Pygmalion effect at work
The effect is not limited to school: it operates wherever there are relationships and expectations — at work, in the family, between managers and team members. Imagine working for two different bosses.
The first has had bad experiences and starts out prejudiced: he thinks young people are all lazy, doesn’t trust you, assigns you only menial tasks, watches you constantly, and never misses a chance to reprimand you. After a few months of this treatment, you would most likely feel demotivated and end up behaving exactly as he feared. His predictions would be confirmed — but he had, in part, built them himself.
The second expects a lot from you without asking the impossible, treats mistakes as part of learning, gives you autonomy while remaining available, and acknowledges your progress. Most likely, you would produce more with him, even without being watched. It is the same mechanism, in the opposite direction: expectations tend to build the reality they take for granted.
What the research does — and does not — say
That said, the Pygmalion effect must be handled honestly. It is not an infallible law or a form of magical thinking: simply “believing” in someone is not enough to make them become what we imagine, and Rosenthal and Jacobson’s original experiment has, over the years, produced replications with conflicting results. Scientifically, there is no full consensus on its scope: the measured effects vary widely depending on context, age, and how the research is conducted.
What research shows with reasonable solidity is more sober, and more useful: expectations can influence how we treat others and ourselves, and that treatment, repeated over time, can encourage or hinder an outcome. It is not destiny. It is a tendency — and precisely because it is a tendency, it can be recognized and changed.
From the Pygmalion effect to mental reprogramming
The reason this topic interests me is simple. When an external expectation is repeated long enough, it stops staying “outside”: it becomes an expectation we make our own, an internalized program, a belief about what we can or cannot be. It is the passage from filtered reality to acquired identity that lies at the heart of Primordial Psychology: the judgments of others, repeated, become the image we have of ourselves.
The good news is that an installed program can be recognized and, with concrete work, rewritten — not with a positive phrase, but by building new evidence that contradicts it. This is precisely the terrain of Mental Reprogramming: transforming the cycles that repeat and the limits we have internalized, starting from how the mind has learned to read itself.
