This article explores the paradox of constructive ambiguity. Based on a focused, longitudinal comparison of the European Union's energy and defense policies, we analyze the role played by strategies of ambiguity in European integration. Ambiguity is found to be an attractive strategy for political entrepreneurs when member state preferences are heterogeneous and the EU's legal basis is weak. It is likely to be effective, however, only if it is embedded in an institutional opportunity structure -, that is, a formal-legal context -that entrepreneurs can fold into their strategic repertoire of ideas. While ambiguity can be strategic in circumstances where clarity would create strong opposition, it is not sufficient to entrench a European policy if it does not rest on an institutional basis. This suggests that European political entrepreneurs should be wary of relying on coalition building by ambiguity only.

In an early formulation of the argument we explore in this article, Stanley Hoffmann (1995[1966]: 131) wrote: "There has always been most progress when the Europeans were able to preserve a penumbra of ambiguity around their enterprise, so as to keep each one hoping that the final shape would be closest to his own ideal, and to permit broad coalitions to support the next moves." Constructive ambiguity has become a received wisdom among Europeanists, a bit like Henry Kissinger's phone number, Jacques Delors's unidentified political object, Donald Puchala's elephant, or the bicycle that cannot stop. Yet it has not been subject to systematic empirical scrutiny.

2While the role of ambiguity remains understudied in EU politics, it is enjoying some currency in related fields such as anthropology, public policy, and international relations. For Murray Edelman (2001: 80), " [a]mbiguity (…) is especially conspicuous in political language because by definition politics concerns conflicts of interests." Indeed, ambiguity is often seen as a means to conceal or to postpone conflict. Using the example of the "social responsibility" label in the mutual fund industry, Linda Markowitz and her colleagues (2012) argue that strategic actors frame financial products ambiguously to reduce negative reactions in the market. Looking at "agencification" in public administ...
