Why Teams Struggle to Make Decisions in Groups Larger Than Six

Written By: Colin Browne

Decision-making weakens in large groups not because people are incapable, but because the emotional dynamics become too complex. More voices mean more hesitation. More personalities mean more caution. More perspectives mean slower progress.

Large groups often avoid conflict to maintain harmony. They choose softer ideas over better ones. They wait for someone else to lead. They adjust their opinions based on who is watching. They prioritise comfort over clarity.

The most effective decision-making groups are small, diverse and decisive. They have enough variety to challenge thinking, but few enough members that responsibility does not diffuse. People speak more honestly, think more bravely and commit more fully.

If a team cannot decide, the team is too big.
