Groups and Organizations

From Coffee Circles to Bureaucracies

A group is people who interact and share identity, not strangers in an elevator. Primary groups (Cooley) are small, intimate, and ends in themselves (family, close friends) shaping who we are. Secondary groups are larger, impersonal, and goal-driven (committees, departments) shaping what we do.

In-groups and out-groups form 'us' and 'them' dynamics, driving loyalty and inter-group conflict. Reference groups are the standard we measure ourselves against, whether we belong to them or not.

Size is destiny. A dyad (2 people) is intense and fragile; one exit kills it. A triad (3 people) invents politics through coalitions and majorities.

Scaling Up and Group Pathology

Pairwise connections explode combinatorially. For $n$ people, the formula is $\text{ties} = \frac{n(n-1)}{2}$. A team of 3 manages 3 ties, but 10 people manage 45. That arithmetic explains why large organizations need process.

Groupthink (Janis) occurs when cohesive groups prize harmony over accuracy, causing dissent to self-censor. Antidotes include a devil's advocate, anonymous feedback, and letting leaders speak last.

Weber's bureaucracy brings a hierarchy of offices, written rules, specialized labor, and merit. But it breeds goal displacement (rules become the goal) and Michels' iron law of oligarchy: democratic groups drift toward rule by the few.

Pitfall: Ignoring the invisible primary groups and in-group lines running underneath formal secondary org charts.
