Proximity Effect: Harvard Economists Explore the Value of In-Person Work for Creativity and Connection

As workplaces continue to evolve, particularly in the wake of significant shifts in how and where people conduct their work, the conversation around remote versus in-person collaboration remains a focal point for organizations globally. Recent insights from Harvard economists Natalia Emanuel, Ph.D. ’21, and Emma Harrington, Ph.D. ’21, offer a compelling perspective on the benefits of physical proximity, suggesting it plays a vital role in fostering creativity, productivity, and growth.

Their work, highlighted in the Harvard Gazette and excerpted from their book, “In Person: How Working Together Fuels Creativity, Productivity, and Growth,” delves into what they term the “Proximity Effect.” This concept posits that working side-by-side allows brains to sync up, making communication, learning, and building on ideas more effortless and effective. For students navigating their own collaborative projects or preparing for future careers, understanding these dynamics can be incredibly valuable. Tools like COSMIQ, a free voice-driven AI tutor, can support individual learning and problem-solving, which then contributes to more effective group work, whether in-person or remote.

The Pixar Example: Engineering Serendipity

Emanuel and Harrington illustrate the Proximity Effect through the iconic example of Pixar Animation Studios. They recount how Steve Jobs, then CEO of Pixar, intentionally designed the company’s headquarters to maximize spontaneous interactions. His vision for a single, large building with a central atrium and even strategically placed restrooms was not merely about aesthetics; it was a deliberate effort to “force people to come together, to create a lot of arbitrary collisions.”

Before this intentional design, Pixar’s teams were scattered across various office parks, leading to isolated groups of writers, animators, and engineers. This fragmentation, according to the economists, contributed to challenges such as the initial, less-than-lovable version of Woody in “Toy Story.” The siloed environment, where writers primarily interacted with other writers, resulted in dialogue that was clever but lacked broader appeal. Once teams were brought together in a space engineered for interaction, the film’s characters evolved, leading to its eventual blockbuster success.

This historical account underscores a key point from the Harvard economists: breaking down silos and encouraging cross-disciplinary interaction can spark creative friction, where ideas are challenged, sharpened, and ultimately improved. John Lasseter, who directed “Toy Story,” initially skeptical of Jobs’s design, later became a convert, noting how the building fostered collaboration and creativity from day one.

The Science Behind In-Person Connection

Beyond anecdotal evidence, Emanuel and Harrington highlight scientific findings that support the Proximity Effect. They explain that face-to-face communication leads to greater neural synchrony – our brains light up in sync, fostering creativity and empathy. In contrast, digital interactions achieve only about a tenth of this neural synchrony. In-person interaction also triggers the release of more endorphins, which are crucial for building trust and rapport, thereby enhancing interpersonal chemistry.

The economists suggest that this biological wiring for in-person connection is often overlooked in discussions about remote work. While sophisticated communication tools abound, their research indicates that they don't fully replicate the benefits of physical presence. For students working on group projects, this suggests that even with excellent online collaboration platforms, periodic in-person meetings might offer a significant boost to team cohesion and innovative thinking.

Remote Work's Impact on Connections and Mental Health

The Harvard economists also delve into the potential downsides of widespread remote work, particularly concerning connection and mental well-being. According to their research, datasets from various organizations and industries consistently show that individuals contact fewer colleagues when working remotely. They cite Microsoft’s experience during its transition to remote work, where employee communication networks shrank and became more siloed, with ties across teams and departments diminishing.

This reduction in cross-cutting collisions, as Pixar discovered, can hinder innovation. Furthermore, Emanuel and Harrington’s research indicates that remote work can contribute to increased loneliness. The office, they note, is a primary place for adults to form friendships. Beyond social connections, they also point to a loss of meaning: while completing a task independently can be satisfying, achieving the same work alongside others often proves more fulfilling and motivating, as shared effort transforms tasks into something greater than the sum of their parts.

While remote work has become significantly more common, with roughly a quarter of American workdays being remote in 2026 compared to 6 percent in 2019, the economists argue that the costs to learning, innovation, and connection are substantial. For parents and educators, these findings offer important considerations when discussing future learning and work environments. Encouraging opportunities for in-person collaboration, even within a hybrid model, could be vital for developing well-rounded individuals capable of innovative thinking and strong interpersonal skills. Resources like COSMIQ's free practice hub can help students build individual mastery, which then empowers them to contribute more effectively in collaborative settings, regardless of whether those are in-person or virtual.

Finding the Balance in a Changing Landscape

The insights from Natalia Emanuel and Emma Harrington do not necessarily advocate for an all-or-nothing approach to remote work. Instead, they provide a robust, evidence-led argument for the powerful advantages of in-person collaboration, particularly in fostering creativity and strong team dynamics. As many industries face disruptive forces, from generative AI to geopolitical uncertainty, the economists suggest that the biggest danger isn't a lack of technical skill, but rather isolation and the resulting creation of solutions that may appear impressive but lack depth or broader appeal.

Their work encourages organizations to consider how they can intentionally design environments and policies that promote the “arbitrary collisions” and spontaneous interactions that are so crucial for innovation and human connection. For K-12 students and those preparing for exams, understanding the value of both independent learning and collaborative engagement can shape their academic journeys and future career paths.
