Hackman's paradox: Groups have natural advantages: they have more resources than individuals; greater diversity of resources; more flexibility in deploying the resources; many opportunities for collective learning; and, the potential for synergy. Yet studies show that their actual performance often is subpar relative to "nominal" groups (i.e. individuals given the same task but their results are pooled.) The two most common reasons: groups are assigned work that is better done by individuals or are structured in ways that cap their full potential.
