Sitting Near a High-Performer Can Make You Better at Your Job

The people we sit near at work shape more than our mood—they can materially change how well we perform our jobs. New research shows that physical proximity to coworkers creates powerful spillover effects that can either boost productivity or amplify dysfunction across an organization.

In a detailed study of more than 2,000 employees at a large technology company, researchers Dylan Minor of Northwestern University and Michael Housman of hiQ Labs analyzed how performance changed based on who employees sat near. By mapping seating locations and tracking performance over time, they were able to quantify how much influence neighbors had on one another.

The researchers found that sitting within a 25-foot radius of a high-performing coworker increased a neighbor’s performance by as much as 15%. When scaled across the organization, this positive spillover was estimated to generate nearly $1 million in additional annual profit.

These gains were strongest when workers were paired with colleagues who had complementary strengths. For example, employees who were slower but high quality improved their speed when seated near fast workers, while fast workers improved quality when seated near high-quality peers. Crucially, strong performers were not dragged down by weaker neighbors.

The researchers emphasize that most modern jobs are multidimensional. There are few true “superstars” who excel at everything. Instead, productivity gains come from thoughtfully pairing specialists so that strengths spill over into coworkers’ areas of weakness.

However, the study also uncovered a darker dynamic: toxic spillover. Toxic workers—defined narrowly as employees who were eventually fired for serious misconduct—had an even stronger impact on those around them than high performers.

When a toxic employee appeared nearby, coworkers’ risk of becoming toxic themselves rose almost immediately. Unlike positive spillover, which was limited to a small radius, toxic influence could be detected across an entire floor. In many cases, the negative effects were roughly twice as powerful as the positive effects created by high performers.

The good news is that toxic spillover dissipates just as quickly as it appears. Once the toxic worker was removed or physically relocated, neighbors’ risk returned to normal levels almost immediately. This suggests that toxic behavior spreads through peer pressure and social cues, rather than long-term learning.

By examining how long spillover effects lasted, the researchers concluded that proximity works primarily through social pressure and inspiration, not skill transfer. Performance changes appeared quickly and faded within one to two months after seating arrangements changed.

The broader implication is clear: spatial management matters. Desk placement is not just an architectural or aesthetic decision—it is a performance lever. With relatively low cost, organizations can increase productivity, reduce risk, and improve outcomes simply by being more deliberate about who sits next to whom.

As companies experiment with open offices, flexible seating, and “nomad” workspaces, this research provides a scientific foundation for those choices. When guided by data rather than intuition, office design becomes a strategic asset rather than an afterthought.
