In 2021, a team of researchers from Carnegie Melon University (CMU) dove deep into the role that browser tabs play in our day-to-day work. Their research was significant in that it identified a root cause of one of today’s most burning problems at the desktop, in tab hoarding. They called the phenomenon the ‘black hole effect’, likening it to a vast digital universe where every open browser tab is a tiny star, each representing a piece of information, a task to complete, or a reminder of things to come. As users navigate this universe, they find themselves surrounded by an ever-increasing number of these stars, reluctant to let any of them fade away.
The CMU team’s research uncovered competing pressures for keeping tabs open (such as fear of losing information and the costs of having to re-locate and surface it again) versus closing them (such as having limited attention, resources, and available space on the desktop). While closing tabs would free up space and declutter the desktop, doing so could plunge the stars into a digital black hole, lost forever. The fear ultimately stemmed from the high cognitive and fine motor costs of re-finding information once a tab is closed. Even bookmarks and grouped or archived tabs represented forgotten constellations—out of sight, out of mind—never to be revisited.
But this digital hoarding wasn’t just about keeping tabs open. It was also about preserving progress and avoiding the daunting task of retracing steps to retrieve valuable insights. The emotional attachment to these tabs was palpable, as each represented a piece of unfinished business, a task in limbo, or a potential missed opportunity.
To tackle the issue, the CMU team proposed innovative solutions similar to those proposed by earlier research on the same topic. Intelligent archiving systems, for example, might gently remind users of their dormant stars. Or, organizing tabs into groups based on activity could help manage tasks and nested sub-tasks more efficiently. They even went so far as to dream up futuristic technology that could automatically resurface tabs and windows when relevant to the task at hand– all without the user taking any action. Still, it all seemed like something out of tomorrow’s world, as our laptops simply did not work like that.
The ‘black hole effect’ highlights the double-edged sword that the web browser has become, as the evolution of the internet and web browsing has outpaced that of the technology we use to navigate it. What began as a convenient method to multitask and organize online activities has now spiraled into the significant cognitive and productivity challenge popularly referred to as ‘tab overload’.
While the CMU research offered valuable insights into the psychology of tab hoarding, it left unexplored the technological factors behind the behavior, raising the question:
What role does technology play in the tab hoarding problem?
