About Thumbtrap.org
The canonical home of the Thumbtrap concept
About This Site
Thumbtrap.org exists to name, define, and document a phenomenon most cell phone and smart phone users experience daily but have never had precise language for.
The term Thumbtrap describes the compulsive scrolling behavioral loop built into smartphones by design. It’s the gap between deciding to stop scrolling and realising, moments later, that your thumb never received the stop signal. It is not a willpower failure. It is the predictable result of three deliberate design mechanisms working in tandem: infinite scroll, variable reward schedules, and personalised algorithm. This combination creates an entire new form of screen time, Screen Plus App Time, which is reinforced through a device’s inter-app operability.
This site is the canonical reference home for the Thumbtrap concept, its research series, and its ongoing development.
About the Author
Garry Jones is a university academic and researcher whose qualifications span education (BEd), psychology and philosophy (BA), marketing (PGDip), business administration (MBA), and research (MRes). This interdisciplinary profile sits at the precise intersection of the forces shaping compulsive smartphone use: human psychology, persuasive design, platform economics, and behavioural learning.
He coined the term Thumbtrap and has developed the concept across a four-article research series that gained renewed relevance following the landmark March 2026 US jury finding that held Meta and Google negligent - not for their content, but for the design architecture of their platforms.
