From B.F. Skinner’s operant conditioning to social media’s behavioural loops – how psychology shapes behaviour, and who uses that knowledge to control us

What is behaviourism? You are being shaped right now. The way this page is designed, the notifications on your phone, the reward loops built into the apps on your device, the pricing strategy in the supermarket you last visited – all of it reflects a century of scientific research into human behaviour and a steady, accelerating application of that research to the project of making you do things. Buy things. Click things. Believe things. Stay.

This is not conspiracy theory. It is, in large part, the history of behavioural psychology – the scientific discipline that began with experiments on rats and pigeons, and ended up helping to design the architecture of the digital world. The person who most comprehensively worked out the principles involved was B.F. Skinner, who spent his career demonstrating, with merciless precision, that behaviour is shaped by its consequences. That the right reward at the right moment can train almost any organism to do almost anything. That free will, as ordinarily understood, may be a useful fiction rather than a biological fact.

What is behaviourism and where did it come from?

Behaviourism, as a scientific programme, was established by the American psychologist John B. Watson in 1913. Watson’s argument was clean and radical: psychology should stop theorising about the mind – about consciousness, will, intention and other invisible entities – and focus instead on what could be directly observed and measured: behaviour. The stimulus, and the response.

This was a methodological claim as much as a philosophical one. Watson wanted psychology to be a science in the same sense that physics or chemistry was a science: predictive, experimental, quantifiable. If you could identify the stimuli that produced a given response, you could, in principle, produce that response reliably. And if you could produce responses reliably, you could shape behaviour. Train it. Control it.

Watson demonstrated this with what is now his most infamous experiment: Little Albert, an eleven-month-old baby who was conditioned to fear a white rat by associating it with a loud, frightening noise. The experiment was ethically indefensible by any modern standard. But it proved Watson’s point: that fear, like any other emotional response, could be conditioned. This insight has haunted psychology, and politics, ever since.

B.F. Skinner and operant conditioning – the science of shaping behaviour

Burrhus Frederic Skinner is the most significant figure in the history of behaviourism, and one of the most controversial scientists of the twentieth century. His contribution was to extend Watson’s stimulus-response model with a crucial addition: the role of consequences. It was not just stimuli that shaped behaviour, Skinner argued, but what followed behaviour – the reinforcements, positive and negative, that made organisms more or less likely to repeat it. He called this operant conditioning.

He demonstrated it with extraordinary precision in his operant conditioning chambers – the so-called “Skinner boxes” – where rats and pigeons learned to press levers in exchange for food. By varying the schedule of reinforcement, Skinner showed he could produce almost any behavioural pattern. And crucially, he showed that variable ratio reinforcement – the random, unpredictable reward – produced the most persistent behaviour. An organism that never knows when the reward is coming will press the lever far longer than one that knows it comes every time.

If this sounds familiar, it should. Variable ratio reinforcement is the principle behind every slot machine, every social media feed, every notification system that might or might not carry something exciting. Skinner described the principle in the 1950s. Silicon Valley engineers read their Skinner. The digital world is, in very large part, an operant conditioning experiment run on a global scale. Read our in-depth profiles of B.F. Skinner and operant conditioning.

“The real problem is not whether machines think but whether men do.”

B.F. Skinner

Operant conditioning in everyday life – schools, apps and society

Operant conditioning is not an abstraction. It is the mechanism by which children learn to read, employees learn to do their jobs, and citizens learn to obey traffic laws. Reinforcement and punishment – praise and blame, reward and consequence – are the basic tools of socialisation. We are all, constantly, involved in conditioning other people and being conditioned by them. This is not sinister in itself. It is simply how social learning works.

What makes it worth thinking carefully about is the scale and deliberateness with which operant conditioning principles are now being applied, and by whom, and in whose interest. The gamification of education – turning learning into points, badges and leaderboards – reflects an understanding of operant conditioning. So does every push notification, every “like” button, every scroll that might or might not surface something interesting.

These are not neutral interventions. Each of them is shaping behaviour in a particular direction, for reasons that serve the interests of whoever designed the system – which is rarely the same as the interests of the person being shaped. Understanding operant conditioning is, in this sense, a form of self-defence.

“The most terrifying fact about the universe is not that it is hostile but that it is indifferent.”

Aldous Huxley

Aldous Huxley and Brave New World – conditioning as political control

Aldous Huxley was not a psychologist. But Brave New World, published in 1932, is among the most perceptive accounts of the political implications of behavioural conditioning ever written. Huxley’s World State conditions its citizens from before birth: through the manufacturing of human beings in batches, and through the conditioning of infants using electric shocks and loud noises to create aversions in the lower castes. The citizens of the World State are not unhappy. That is the point. They have been shaped to find happiness precisely in the kind of lives the stability of the state requires them to live.

Huxley’s warning resonates more powerfully in the digital age than it did in 1932. The World State’s conditioning mechanisms are primitive compared to the precision with which today’s platforms can target, test and reinforce specific behaviours in specific individuals. The soma of Huxley’s dystopia was a crude sedative. The soma of the twenty-first century is personalised, algorithmic, and invisible. Read our full profile of Aldous Huxley.

Big tech, surveillance capitalism and the industrialisation of behaviour

Shoshana Zuboff’s concept of surveillance capitalism – developed in her 2019 book of the same name – provides the most comprehensive account of what has happened when behavioural science and digital technology have been combined at scale. Surveillance capitalism, as Zuboff describes it, is an economic logic: it extracts human experience as raw material, processes it into behavioural predictions, and sells those predictions to advertisers and others who want to shape what people buy, vote for and believe.

Every search query, every click, every pause in a video, every route taken to work is a data point that feeds a model of human behaviour that is then used to predict and influence future behaviour. The companies that operate this system are not simply selling advertising. They are selling certainty about what people will do. And the more accurately they can predict behaviour, the more valuable their product. Read our related articles on big tech and surveillance capitalism and social media’s double edge.

The ethics of behaviour change – who has the right to shape us?

The most fundamental question raised by behavioural psychology is not empirical but ethical: who has the right to shape human behaviour, and on whose authority? This question runs through every application of the science, from the classroom to the psychiatric ward to the smartphone.

Skinner himself was not unaware of it. His 1948 novel Walden Two imagined a utopian community designed on behaviourist principles. His critics, most notably the philosopher Noam Chomsky, argued that Skinner had fundamentally misunderstood what it meant to be human: that the reduction of human beings to stimulus-response machines was not a scientific discovery but an ideological position, one that served the interests of those who wished to manage and control other people.

The debate between Skinner and Chomsky about the nature of language and freedom, conducted in the 1970s, remains one of the most important intellectual confrontations of the twentieth century. The argument has not been resolved. But what has changed is the scale and precision with which behaviour-shaping technology has been deployed – which makes the ethical question more urgent than it has ever been.

Cognitive behavioural therapy and nudge theory – behaviour change for good

Not all applications of behavioural psychology are in the service of corporate profit or political manipulation. Cognitive behavioural therapy – CBT – is one of the most evidence-based and widely used treatments for depression, anxiety and a range of other mental health conditions. It uses insights from behaviourism and cognitive psychology to help people change the way they respond to the world.

Nudge theory, developed by behavioural economists Richard Thaler and Cass Sunstein, applies similar insights to public policy: by changing the architecture of choices – making the healthy option the default, requiring an opt-out rather than an opt-in – governments can shape behaviour without coercion. Organ donation opt-out systems, the placement of fruit at eye level in canteens, automatic enrolment in pension schemes: these are all nudges, and the evidence suggests they work.

The ethical question here is whether it is acceptable for governments and institutions to shape our choices without our awareness. Thaler and Sunstein argue yes, provided the nudges are transparent and the choice remains available. Critics argue that there is something troubling about a policy that works precisely because people are not thinking about it.

“Freedom is not an absence of commitment, but the ability to choose.”

Paulo Coelho

Why behaviourism matters now – knowing how you are shaped

The history of behaviourism is, ultimately, a history of a discovery and a problem. The discovery is genuinely important: that behaviour is shaped by consequences, that patterns of reward and reinforcement produce patterns of action, and that these patterns can be understood scientifically and altered deliberately. This is useful knowledge. It is the basis of education, therapy, public health policy and a great deal else that matters.

The problem is equally genuine: the same knowledge can be, and is being, used to shape behaviour in the interests of those with resources – corporations, political movements, states – without the knowledge or consent of those being shaped. And the scale at which this is now happening, through digital platforms that interact with billions of people daily, is historically unprecedented.

Know how you are being shaped. That is the beginning of something.
