Development models are disputed in the global South and North, as evidenced by recent protests advancing different desirable social ends and means. The diversity of development ideas suggests it is a wicked problem, requiring clumsy solutions. Employing grid group cultural theory, this article elucidates that plurality and indicates ways to harness it. Four irreducible, ideal‐typical notions of development are found: market‐led individual prosperity, state‐led system‐wide welfare, alternatives of community‐led equal welfare with ecological conservation and a mirage. Clumsy development models secure legitimacy and effectiveness by engaging all worldviews, including their distinct pathways to clumsiness or messy institutions.
