In 2006, a young interface designer named Aza Raskin was sitting at his computer, searching through Google, and getting quietly annoyed.
The frustration was simple. Every time he reached the bottom of a page of results, he had to stop, find the button, click, and wait. A tiny interruption. A small but real break in what should have been a smooth, continuous experience. It was not dramatic. It was not a crisis. It was just friction, the kind that most people tolerate without thinking. But Raskin thought about it.
He asked a question that designers rarely ask because the answer seems too obvious to pursue: what if you never had to stop?
What if, instead of a page ending, the content just continued? What if scrolling down simply produced more, automatically, without clicking, without waiting, without the small cognitive disruption of deciding whether to continue?
The answer to that question was the infinite scroll. And Raskin built it in 2006, working at Humanized, a computer user interface company, with what was, by all accounts, a completely genuine intention. He wanted to make the experience of browsing the internet easier. More human. Less mechanical. He was not trying to trap anyone. He was trying to remove a small annoyance from people's days.
He succeeded. And then something else happened entirely.
The Weapon He Did Not Mean to Build
Social media companies took what Raskin built and understood something about it that he had not fully reckoned with. They understood that removing friction did not just make an experience easier. It made stopping almost impossible.
On a paginated website, every click is a small decision. Do I want to see more? The answer is usually yes, but the asking of the question creates a moment of consciousness. You are aware, for a second, that you are choosing. Infinite scroll eliminated that moment. There is no decision. There is only the continuation of the action already in progress. Your thumb moves and the content comes. Your thumb moves and more content comes. There is no natural endpoint, no boundary where the experience concludes, nowhere the interface tells you that you are done.
Instagram adopted it. Twitter adopted it. Facebook adopted it. TikTok took the logic even further, making the entire format a vertical infinite scroll where one video ends and the next begins before you have consciously decided to watch it. The mechanism that Raskin designed to reduce frustration became, in the hands of platforms whose business model depends on time-on-screen, one of the most effective attention capture tools ever built.
Raskin has since said that his creation wastes the equivalent of roughly 200,000 human lifetimes every single day. He co-founded the Center for Humane Technology with Tristan Harris and helped produce the Netflix documentary The Social Dilemma. He has spent years trying to explain what went wrong. He has also said something that deserves to be read slowly by every person who builds a brand or a product:
"Optimizing something for ease-of-use does not mean best for the user or humanity."
That sentence is a masterclass. Sit with it for a moment.
Why Social Media Became the Most Powerful Marketing Engine in History
Social media is not the most powerful marketing engine in modern history because of targeting algorithms, though those help. It is not because of reach, though the numbers are staggering. It is the most powerful marketing engine in modern history because it was built on a precise and serious understanding of human behaviour.
The infinite scroll was only one piece. Around it, the platforms layered variable rewards, the same psychological mechanism that makes slot machines so difficult to walk away from. You do not know what the next post will be. It might be something that moves you. It might be something that makes you laugh. It might be someone you miss. The uncertainty is the engine. Humans are wired to seek resolution to uncertainty, and an infinite feed never resolves. It just continues.
They added social validation in the form of likes and comments, tapping into the deepest human need for acknowledgment and belonging. They made sharing frictionless. They made notifications feel urgent. They designed interfaces where the actions that serve the platform, posting, engaging, reacting, are the easiest actions to take. Everything difficult was removed. Everything that kept you on the platform was made effortless.
This is anthropology. Not in the academic sense. In the practical, operational sense. These companies studied how human beings actually behave, not how they say they behave, not what they claim to value, but what they actually do when given the choice, and then they built environments perfectly calibrated to that behavior.
The lesson for brands is not to make your product addictive in a way that harms people. The lesson is that the companies who understand human behavior most deeply build the things that human beings cannot stop engaging with. And that understanding starts long before you design anything.
What Aza Raskin Actually Taught Us About People
Raskin did not set out to study human psychology. He set out to solve a design problem. But in solving it, he revealed something true about how people work, and that truth has applications far beyond website design.
Here is what his work tells us:
People do not stop unless something makes them stop. This sounds obvious but most brands design the opposite of it. They create stopping points everywhere: forms that require too much information, checkout processes that take too many steps, physical queues that move too slowly, customer service lines that put people on hold. Every one of these is a "Next Page" button. Every one of them is a moment where a person has to consciously decide whether to continue. And many of them will decide not to.
People move in the direction of least resistance. This is not a flaw in human character. It is simply how attention works. When the path forward is clear and easy, people keep moving. When it is unclear or effortful, they pause, get frustrated, and sometimes leave altogether. Raskin removed the effort from browsing and people browsed endlessly. The same logic applies to every brand interaction, in every channel, in every context.
People are motivated by what they might discover next. Curiosity is one of the most underused tools in marketing. The anticipation of what comes next is often more powerful than the thing itself. Raskin's scroll kept people moving because they never knew what was waiting just below the fold. A brand that gives people a reason to wonder, to return, to see what is new, is working with this same current.
People need prompts to disengage. Without a cue to stop, most people will not stop. This is not weakness. It is the natural behavior of an attention system that conserves decision-making energy wherever it can. Brands that make disengaging difficult benefit from this. Brands that make re-engaging easy, through reminders, updates, or moments of novelty, are using the same insight in the other direction.
The Table: Raskin's Principles, Online and Offline
The principles behind infinite scroll are not digital principles. They are human principles. Which means they apply everywhere a brand touches a person, on a screen, in a shop, on a phone call, at an event.
| Behaviour Insight | Online Application | Offline / Human Application |
|---|---|---|
| Attention prefers flow | Website with no unnecessary page breaks, smooth navigation, content that loads without interruption | A physical store where the layout guides you naturally from one section to the next, no dead ends, no confusing signage |
| Humans avoid friction | One-click checkout, autofill forms, fast-loading pages, minimal steps from discovery to purchase | A queue management system that moves fast, a receptionist who checks you in without excessive paperwork, packaging that is easy to open |
| Curiosity for novelty | Personalised feeds, "you might also like" sections, email subjects that create genuine anticipation | Seasonal menu changes, a retail window that is always being refreshed, a staff member who tells you about something new without being asked |
| Lack of stopping cues | Autoplay, seamless transitions between content, no forced log-outs or session timeouts | A lounge area in a store that invites people to stay, ambient music calibrated to slow the pace, a salon that offers a drink before you sit down |
The two columns above are not different disciplines. They are the same discipline applied in different environments. A website that loads in under two seconds and a till queue that moves in under two minutes are solving the same human problem. A notification that reminds a customer about something they left in their basket and a sales assistant who follows up a visit with a message are doing the same thing. The medium changes. The understanding of the human being does not.
The Caveat Raskin Gave Us
There is a version of all of this that goes wrong. Raskin is the proof.
He optimised for ease of use and created something that, in the hands of companies with the wrong incentives, became genuinely damaging. The same seamlessness that makes something easy to use can make it impossible to put down. The same understanding of human behaviour that makes a brand feel generous and kind can be used to manipulate and extract.
The difference, ultimately, is intention.
A brand that removes friction because it genuinely respects its customer's time is doing something different from a brand that removes friction because it wants to extract more money before the customer has a chance to think. A brand that uses curiosity to give people something worth discovering is doing something different from a brand that uses it to manufacture false urgency and desire that was never real.
Raskin's deepest lesson is not a design lesson. It is an ethical one. The more precisely you understand human behaviour, the more responsibility you carry. The better you are at this, the more carefully you must ask: what am I optimising for, and who does it actually serve?
The best brands already know the answer. They build for the person, not the metric. And because they do, people do not just engage with them. They return to them, tell others about them, and carry them, quietly, into the culture.
Which is, in the end, the only place a brand that lasts has ever truly lived.
