Quick answer: Who invented infinite scroll, and why does he regret it?
- The inventor — Aza Raskin designed infinite scroll in 2006 at Humanized, as a way to stop making people click to the next page.
- What changed it — paired with personalised, algorithmic feeds on social apps, a convenience became a design for open-ended use.
- Why it hooks — it removes stopping cues, the natural breaks where people decide whether to continue, and delivers unpredictable rewards.
- His regret — Raskin co-founded the Center for Humane Technology and has said he wishes the design had been used differently.
- Regulation — the EU's February 2026 preliminary finding against TikTok named infinite scroll; New York's SAFE for Kids Act restricts addictive feeds for minors from January 2027.
Key takeaways
- Infinite scroll is not harmful by itself: it suits image search and timelines, and hurts tasks that need comparison or a sense of progress.
- The behavioural mechanism is the removal of stopping points: without a page end, the decision to stop never comes up.
- Unpredictable content (sometimes great, usually ordinary) is a variable-reward schedule, the pattern that sustains habits most strongly.
- Even commercially, infinite scroll can backfire: Etsy's search test found people clicked and favourited less.
- Design responsibly: add natural breaks, show progress, and give people an easy way to set their own limits.
In 2006, Aza Raskin was in his early twenties, the son of Jef Raskin, the man who started Apple's Macintosh project. Working at Humanized, a small interface company he had co-founded, he noticed something wasteful about the web: every page of search results ended in a row of numbers you had to click to see more. Each click was a small interruption. So he built a page that simply loaded more results as you approached the bottom. It was elegant, it saved effort, and it spread everywhere. A decade later, combined with feeds built to hold attention, it had become one of the most criticised designs on the internet, and its inventor one of its most prominent critics.

Who invented infinite scroll?
Aza Raskin invented infinite scroll in 2006. The technique loads new content automatically as a person nears the end of what is on screen, so there is never a last item or a "next page" link1. Raskin's goal was the classic one of good interface design: remove unnecessary effort.
What turned it from a convenience into a controversy was what it was paired with. From around 2009, social networks replaced chronological lists with personalised, algorithmically ranked feeds designed to maximise time spent. An endless list of content chosen to be engaging, with nothing to tell you that you have reached the end, keeps people going far longer than they plan to.

Why does infinite scroll keep people scrolling?
Infinite scroll keeps people scrolling because it removes the moments at which they would otherwise decide to stop. Two well-studied mechanisms work together.

No stopping cues
A chapter end, the last page of results, the end of a TV episode: these are natural points where we re-evaluate. Infinite scroll removes them, so the decision to stop has to come from inside, against momentum.
Variable rewards
In a personalised feed, most posts are ordinary and a few are delightful, at unpredictable intervals. Behavioural research since B. F. Skinner has shown that this variable schedule of reward sustains behaviour far more persistently than predictable rewards (see variable reward).
Low effort per step
Each extra post costs only a flick of the thumb. When the cost of continuing is near zero and the cost of stopping is a decision, continuing wins.
Lost sense of time
Without page numbers or an end, there is no visible measure of how far you have gone, which makes time easy to underestimate.
A field study published at the MobileHCI conference in 2023 by Jan Ole Rixen and colleagues at Ulm University tracked 46 people's social media sessions for a week. They described an "inner loop" of scrolling within a session inside an "outer loop" of habitual reopening, and found that most sessions ended because of something outside the app, such as an interruption or a change of context, rather than a cue inside it4. In other words, the feed itself rarely gives people a reason to stop.
The inventor's regret
Raskin has been open about his regret. In interviews he has said that he designed infinite scroll to make browsing easier and did not foresee it becoming a tool for capturing attention, and he has offered rough, admittedly uncertain estimates of how much collective human time it consumes1. In 2018 he co-founded the Center for Humane Technology with former Google design ethicist Tristan Harris, to argue for technology designed around people's wellbeing rather than their time on screen3.
He is not the only designer to feel that way. Loren Brichter, who created pull-to-refresh for his Twitter app Tweetie, told The Guardian in 2017 that pull-to-refresh is addictive and that he had regrets about it; the article compared the gesture to pulling the lever of a slot machine2.
Is infinite scroll good or bad design?
Infinite scroll is a tool that fits some tasks and hurts others. The Nielsen Norman Group's guidance is that it suits feeds of similar, equally weighted items where people browse without a specific goal, and it hurts tasks that need comparison, orientation or a sense of completion5.

Works well for
- Image search and photo browsing
- Social timelines and news streams
- Discovery when people have no specific target
- Mobile, where tapping small page links is awkward
Works badly for
- Shopping, where people compare and return to items
- Search tasks with a specific goal
- Pages whose footer holds essential links
- Anything where progress or 'done' matters
The business case is not automatic either. In a talk on experimentation, former Etsy engineer Dan McKinley described Etsy's test of infinite scroll on search results: people who saw it clicked fewer results and favourited fewer items, and bought fewer items from search, though overall purchases did not fall6. The team concluded it had assumed "more items, faster" was better without testing that assumption.
Regulators are now treating feeds as a design problem
Regulators have begun to treat endless feeds as a product safety issue. On 6 February 2026 the European Commission issued preliminary findings that TikTok's addictive design, naming infinite scroll, autoplay, push notifications and its recommender system, breached the EU's Digital Services Act, and suggested the company might need to change its basic design, for example by disabling infinite scroll and adding effective screen-time breaks7. The findings are not final; TikTok can respond, and a confirmed breach could bring a fine of up to 6% of worldwide turnover.
In the United States, New York's SAFE for Kids Act, signed in 2024, bars covered platforms from showing algorithmically personalised "addictive feeds" to users under 18 without parental consent; the state's final rules were released in July 2026 and take effect on 25 January 20278.
How to design feeds people don't regret using
You can keep the convenience of continuous loading without the regret. These are design choices product teams control.

- Add natural breaks — after a set number of items, show a clear "you're all caught up" or a summary, as Instagram did in 2018.
- Show progress where it matters — counts, sections or dates give people a sense of where they are.
- Use 'load more' for goal-driven lists — a button keeps the footer reachable and makes continuing a choice.
- Remember position — returning to a list should restore the scroll position, a common failure of infinite lists.
- Give people real controls — time limits and quiet hours that are easy to set and hard to dismiss by accident.
- Measure regret, not only time — ask users whether time in the app felt well spent, and treat that as a product metric.

Frequently asked questions
Who invented infinite scroll?
Aza Raskin, an American interface designer, created infinite scroll in 2006 while working at Humanized, a small user-interface company he co-founded. The idea was to load more results automatically as people reached the bottom of a page, instead of making them click to a new one. He later co-founded the Center for Humane Technology.
Why does Aza Raskin regret infinite scroll?
Because of how it came to be used. Raskin designed it to save effort, but social media companies combined it with algorithmic feeds tuned to keep people engaged. Without the natural breaks of a page end, people lose track of time. He has said he did not anticipate those uses and has campaigned for more humane design since 2018.
Why is infinite scroll addictive?
Two mechanisms combine. It removes stopping cues, the moments at the end of a page or episode when people decide whether to go on. And a personalised feed delivers unpredictable rewards, occasionally something great among the ordinary, which behavioural research shows is the reinforcement schedule that sustains behaviour most persistently.
Who invented pull to refresh?
Loren Brichter, an iOS developer, introduced pull-to-refresh in his Twitter app Tweetie around 2008 to 2009; Twitter later bought the app. In 2017 Brichter told The Guardian that the gesture is addictive and that he regrets aspects of it; critics compare pulling down for new content to a slot machine.
Is infinite scroll bad for UX?
Not always. It works for browsing streams where people have no specific goal, such as image results or social timelines. It works poorly when people need to compare items, return to a position, reach a footer or feel progress towards a goal, which is why many shops and search engines still use pages or a 'load more' button.
Is infinite scroll being banned?
Not outright. In February 2026 the European Commission preliminarily found that TikTok's addictive design, including infinite scroll, breached the Digital Services Act and suggested it might need to disable infinite scroll; the case is ongoing. New York's SAFE for Kids Act restricts addictive feeds for under-18s from January 2027.
