Stockholm, 1943: The Birth of an Idea That Had Not Yet Been Named
This idea emerged long before the term 'IKEA effect' existed — even before IKEA became a global name. In 1943, 17-year-old Ingvar Kamprad from the Småland region in southern Sweden founded a small business named
IKÉA — an acronym derived from his name (Ingvar Kamprad), his family's farm (Elmtaryd), and the name of his village (Agunnaryd). Initially, he sold pencils, thread, and picture frames through the post. But a hidden principle was planted from the beginning:
if customers participate in the creation process, they will feel more ownership.
When IKEA began producing furniture in 1956, Kamprad made a radical decision: to sell all furniture in flat-pack form — boards, screws, and assembly instructions in one box. Not just to save on shipping costs, but because he realized something intuitive: when someone assembles a table themselves, the table is no longer just a purchase — it becomes a story. And stories, as historians know, are the most durable currency in human memory.
Cambridge, 2011: An Experiment That Reinforced an Old Theory
Forty-eight years after IKEA started selling labeled 'BILLY' wooden boxes, a team of researchers at Harvard University and Duke University — Michael I. Norton, Daniel Mochon, and Dan Ariely — conducted a series of experiments that later became a scientific milestone for the concept of the 'IKEA effect'. They did not study the market or sales; they studied
feelings.
In one study, participants were asked to build a origami crane from paper. Half of them were given step-by-step instructions; the other half were left to try on their own without guidance. The results were surprising: those who struggled longer and made more mistakes evaluated their work twice as high as independent evaluators — and were willing to pay 63% more to own it. This is not just pride; it is a cognitive adjustment — our brains automatically increase the value of objects we have invested time, energy, and emotion into.
From the BILLY Table to the Parthenon Temple: Historical Roots in Self-Construction
This phenomenon is not a product of the 21st century. Since ancient Greek times, humans have associated meaning with physical effort. In 5th-century BCE Athens, citizens did not just pay stonemasons — they participated in the
Panathenaic Festival, where every citizen contributed a stone, carving, or paint for the Parthenon. Not all stones were placed by professional masons; many were placed by amateur hands — and thus, the temple was not only a symbol of Athena, but a symbol of
collective ownership.
Similarly, in Malay tradition: traditional stilt houses are not built by a single contractor, but by gotong-royong — each family contributes wood, nails, and labor. When the house is complete, it is not just a home, but a shared heritage, where each pillar reminds of the name of the person who hammered it, and each roof tells of the person who lifted the beam. The value of the house is not measured in square feet, but in the number of hours spent under the heat, in the shared fatigue endured.
Our Brains and the Illusion of 'I Made This'
Modern neuroimaging shows that when someone completes a construction task — even just assembling a wall shelf — the
ventromedial prefrontal cortex (vmPFC) becomes active. This area is closely linked to subjective value assessment and emotional decision-making. In other words, our brain does not differentiate between 'I bought this' and 'I created this' — it only recognizes 'I was involved in this'.
More interestingly: this effect decreases drastically when the effort fails. In a follow-up experiment, when participants failed to assemble an IKEA shelf, the value they assigned dropped below the market price — not because of low self-esteem, but because of loss of ownership feeling. Thus, the IKEA effect is not just about effort, but about the experience of control and achievement — two elements that have been the backbone of human motivation since the Stone Age.
Legacy That Still Echoes in Every Turned Screw
Today, the IKEA effect goes beyond furniture. It appears in digital kitchen apps that allow users to 'create their own menu', in educational platforms that ask students to build 3D models from scratch, and in community movements that encourage residents to develop urban gardens from empty land. All of these are not just marketing strategies — they are deep reflections on human nature: we do not just want to own things, but to
own meaning.
And when you next hold a small screw and read the obscure Swedish instructions, remember: you are not just assembling a shelf. You are joining an ancient ritual — a ritual where manual effort becomes the thread that binds the soul to the object, and where each turn of the screw reinforces that what we make, we love — not because it is perfect, but because it is ours.

Why Are We Willing to Pay 63% More for Furniture We Assemble Ourselves?. In 2011, a psychology experiment shocked the academic world — participants were willing to pay almost twice as much for a wooden chair they assembled themselves, even though its form and function were identical to the ready-made version. Why can such a small physical effort change the emotional and economic value of an object? The answer is not in the IKEA catalog, but in the deepest layers of the human brain..
