Based on Dunbar's neocortex research showing cognitive limits on group size, Laughlin et al.'s finding that groups of three outperform even the best individuals, and Latané et al.'s landmark social loafing study showing individual effort drops to 40% in groups of six. 🎯 IN THIS VIDEO YOU'LL LEARN: ✅ Why your team struggles — even when everyone is talented and committed ✅ The dyadic pairs formula that shows exactly why adding one person creates six new problems ✅ What Oxford researcher Robin Dunbar discovered about the cognitive limits of group size ✅ Why individual effort drops to 40% in groups of six — and what that means for your PLC ✅ Why groups of three outperform even the best individual on problem-solving tasks ✅ How the right group size varies by task type — brainstorming, data analysis, decisions, and protocols each require a different configuration ✅ How to use the free Team Size Optimizer app to calculate your optimal group split in seconds ✅ Exact facilitator language for proposing a group split to your team Monday morning ✅ How roles like facilitator, timekeeper, notetaker, and reporter shift based on group size ✅ What your role as team leader or coach looks like when you step out to run the session 🎁 FREE TOOL: Team Size Optimizer — enter your team size and task type, get your optimal group configuration, role assignments, and exact facilitator language instantly: https://teamingedge-teamsize.netlify....

(1992) — Neocortex size limits the number of relationships humans can actively monitor; when a group exceeds this limit, it becomes unstable and begins to fragment Laughlin, P.R., Hatch, E.C., Silver, J.S., & Boh, L. (2006) — Groups of 3 are necessary and sufficient to outperform even the best individuals on problem-solving tasks; adding a 4th or 5th member provides no measurable benefit Latané, B., Williams, K., & Harkins, S. (1979) — Individual effort drops to 40% in groups of six; social loafing increases with every person added Mullen, B., Johnson, C., & Salas, E. (1991) — Productivity loss in brainstorming groups scales with every person added; per-person contribution declines as group size increases Steiner, I.D. (1972) — Process loss framework: Actual Productivity = Potential Productivity − Process Losses; losses increase with group size through both coordination and motivation mechanisms 👍 Like if this changes how you think about team size 🔔 Subscribe for weekly research-backed strategies for K-12 team leaders 💬 Comment: How do you currently break your team into smaller groups?
