Proximity Decay

In the age of instant digital communication, we operate under the assumption that physical distance no longer matters. With video calls and endless messaging channels, a colleague across the globe should be just as accessible as one sitting at the next desk. Yet, the fundamental geometry of human behavior refuses to adapt to our software.
In the late 1970s, MIT professor Thomas Allen discovered a ruthless mathematical truth known as the Allen Curve. He proved that the frequency of communication between engineers drops exponentially as the physical distance between their desks increases. Beyond 50 meters, regular communication effectively plummets to zero. Astonishingly, recent data proves that even with digital tools, the Allen Curve remains unbroken. We do not email, message, or video call people we do not physically cross paths with. When companies shift to fully remote work, the casual collisions that spark innovation vanish, siloing teams and quietly suffocating creative momentum.
This book dissects the architectural psychology of the workplace and the limits of virtual connectivity. It explores why spontaneous friction cannot be scheduled and why the physical layout of a building dictates the intellectual output of its occupants.
You will learn how to engineer proximity, overcome the spatial decay of remote work, and rebuild the invisible networks of trust that power true organizational velocity.
