Research favors task cohesion over social bonding in high-performing teams
Organizational psychologist Adam Grant argues that alignment on shared goals drives performance more effectively than personal friendship. He recommends leaders adopt distinctive, limited core values and prioritize cultural contribution over conformity to avoid groupthink.
Organizational psychologist Adam Grant contends that effective teams rely on task cohesion, or bonding to a common goal, rather than social cohesion, which is defined by personal friendship. Grant cites data from work and sports teams indicating that task cohesion is a stronger driver of performance. To foster this alignment, he suggests leaders "outsource inspiration" by bringing customers or end-users into the workplace to demonstrate the tangible impact of the work, a strategy he argues creates stronger motivation than executive articulation alone.
Grant’s approach to team culture was applied with the U.S. Women’s National Soccer Team, where he helped replace generic values like "winning" and "teamwork" with four distinctive, rank-ordered core values. These included "leave it better," a specific accountability metric, "bloodbath mentality," and "don't be an asshole." Grant notes that colleague Drew Carton found organizations should maintain a maximum of four core values to ensure they remain memorable and consistently defined. This specificity helps channel differences toward a higher purpose, preventing the groupthink that can arise when companies prioritize cultural fit over skills. A 15-year study of biotech startups supported this, showing that high cultural fit led to lower failure rates pre-IPO but slower growth post-IPO due to homogeneity.
Onboarding practices also reflect this focus on contribution. Research by doctoral student Konstantinos Kutiferis shows that "pre-boarding," or contacting new hires two weeks before their start date, accelerates cultural learning. Additionally, colleague Dan Cable suggests inviting new hires to "stand out" rather than "fit in" improves retention. A Wipro experiment where new hires shared personal career highlights resulted in higher performance reviews and lower quit rates after six months. Grant also notes that having just one friend at work, as found by colleague Segal Barsade, is sufficient to prevent feelings of loneliness, challenging the necessity of deep "best friend" connections for all team members.
