Team norms, not talent, drive high performance

Executive overview

Most leaders focus on hiring smart, interpersonally skilled people — but individual talent and EQ don't predict team performance. What determines how well a team functions are its norms: the routines and habits that shape how members interact.

Belonging is the foundational social need in team settings. When people don't feel known and accepted by peers, they self-protect, withhold information, and underperform. Leaders set the conditions for belonging — even though they're often the least likely to notice its absence.

The single most important norm in high-performing teams is that members genuinely know one another.

Why individual talent and EQ aren't enough

• Teams are social systems — what matters is how people interact, not the skills they possess individually
• Even the most empathetic person won't use empathy if the group's norms don't support it
• Belonging is an innate, involuntary need — people are only aware of it when it's missing
• High-status members (including leaders) feel automatic belonging and routinely underestimate how much others lack it
• When people don't feel they belong, they guard themselves, share less, and match the minimum contribution they observe in others

The norm of understanding team members

• In the highest-performing teams studied, members knew each other's strengths, weaknesses, and working styles
• This knowledge enables precise coordination — equivalent to knowing how to pass to a specific teammate in sport
• In task-focused teams, relevant knowledge includes: past roles, what excites or worries someone, what they need from the team
• In relationship-focused teams, personal context (family, interests, weekends) fills in the picture
• Feeling known is a core component of belonging — it unlocks full contribution and trust

Practices for building team knowledge

• Check-ins at the start of meetings: one question per person, ~20 seconds each; rotate who sets the question
  • Useful questions: "What's top of mind?", "What are you worried about in the team?", "What do you need from us?"
  • Log anything significant that surfaces but park it for later — don't let it derail the agenda
• Gallery walks: each person answers a prompt (e.g. "What do you need from this team to perform at your best?") on a slide or flip chart; others read and annotate without requiring full discussion
• Object sharing: ask members to bring an object representing what a great team means to them — bypasses verbal difficulty and reveals personality through stories
• Slide profiles: each person creates a short deck with their background, skills, best contact times, and a photo; especially effective for remote and hybrid teams
• Trip reports (from Bill Campbell's practice): open meetings by having each person share where they've been and what they noticed — surfaces expertise, reduces silos

Changing norms from within the team

• Leaders have the most leverage over norms — they control the agenda and model the habits
• Members can also shift norms, but it requires allies: find one or two others willing to raise the issue
• Start with one small norm (e.g. getting everyone to speak in meetings) — changing one norm tends to unlock others
• Frame it as a question to the team: "Why isn't everyone participating? What could we change?"
• Progress is slower from the grassroots but is achievable
