Dropbox Weighs Cognitive Training to Counter AI 'Brain Rot' in Staff

Dropbox is weighing memory exercises and attention-span training for its employees, betting that deliberate cognitive workouts can offset the mental decline some researchers link to heavy AI use at work.

The company's chief people officer, Melanie Rosenwasser, laid out the thinking in an interview with Fast Company. "We're incredibly optimistic about [AI's] impact, but we also believe we have a responsibility to understand how it's affecting the people who use it every day," she said.

What does this change for employers?

The move puts a name on a problem many HR teams have been circling without addressing head-on: "brain rot." The term has gained traction as a shorthand for cognitive decline attributed to AI tools and social media, with studies lending it credibility. If Dropbox formalizes cognitive training, it creates a template other employers can copy — and a new line item in the people-operations budget.

The San Francisco-based cloud storage pioneer has already run experiments. Executives have taken part in "analog" offsites where they practice breathwork and set aside their electronic devices entirely. Now the company is going further, looking at structured brain-health programming.

"That's why we're beginning to explore training around brain health and cognitive well-being, while also experimenting with ways to foster critical thinking and human connection," Rosenwasser said.

She's careful not to oversell it. "We're approaching this with curiosity and humility, recognizing that this is an emerging area where there is still a lot to learn," she said.

Does brain training actually work?

Here practitioners should apply some skepticism of their own. Evidence is limited that brain-training exercises improve general intelligence. The honest framing: general IQ gains are unproven, but targeted drills may deliver durable gains in specific mental skills.

The strongest datapoint comes from a National Institutes of Health-funded study. It found that training in reasoning and processing speed produced benefits lasting up to a decade in older adults. Ten years of measurable return on a training intervention is a serious result, even if the study population skews older than the typical Dropbox employee.

That nuance matters for any company sizing up a similar program. You're not buying smarter workers. You're potentially buying sharper specific skills — reasoning speed, sustained attention — and, if the early corporate pilots are any guide, some self-reported gains in focus.

Who else is doing this?

Dropbox would not be the first company to put cognitive fitness on the corporate menu, and the precedent is instructive.

• JLL. Last year, the commercial real estate giant set up a "brain gym" in its Singapore office featuring "lighted pods" and "vision training boards." Workers who participated reported better focus and fewer distractions, according to Business Insider.
• Fischer. In 2024, the commercial real estate firm partnered with the University of Texas at Dallas on a three-month trial program intended to "improve cognitive performance and support better work habits."

The Fischer results deserve a closer look, because they came with measurement attached. Researchers said the workers showed measurable progress on a composite index covering "cognitive capacity, sense of well-being, quality of social interactions and complexity of daily routines." That's a broader basket than raw processing power — it treats cognition as entangled with how people feel and connect at work, which tracks with Dropbox's own emphasis on "human connection."

The so-what for people leaders

The pattern forming here is hard to miss: real estate firms ran the pilots, and now a major tech company — the industry most exposed to AI-driven work habits — is exploring the same toolkit. That sequencing suggests corporate brain health is moving from wellness-adjacent novelty toward a definable program category.

For Dropbox, the stakes are direct. Its employees sit at the exact intersection where AI adoption is deepest and the cognitive offloading debate is loudest. Whether memory drills and breathwork offsites become standard corporate practice, or end up as a well-intentioned experiment with thin evidence, will depend on whether programs like these can show the decade-scale durability the NIH research found — in a workforce that is younger, busier and more skeptical than a study cohort.
