Integrative Social Contracts Theory is a popular framework to assist managers in making decisions on international moral dilemmas. Although the theory has been praised for its comprehensiveness and sophistication, commentators have raised concerns regarding the justification and identification of substantive hypernorms, fundamental moral principles valid across cultures. This paper introduces the deliberative test, a new method for testing the cross-cultural validity of ethical norms in ISCT. The test relies on the concept of Deliberative Capacity, arising from new developments in system-level (...) deliberative democracy research, which studies deliberation at the level of national societies and over time. Based on this recent stream of research, the deliberative test has the potential of providing better guidance for managers to decide which norms to follow in case of conflicting standards between home and host countries.
