A groundbreaking study tested 33 moral issues across 94 societies, revealing a formula that accurately predicts the direction and rate of moral norm changes. This extensive research encompassed diverse cultural contexts, offering a comprehensive view of how human values evolve over time. The findings suggest that the seemingly spontaneous shifts in societal morality adhere to discernible patterns.

Moral evolution is often perceived as chaotic and unpredictable, but new research reveals a quantifiable formula that can forecast its direction and rate. This tension between perceived randomness and emerging predictability forms the core of a recent investigation.

Understanding the underlying mechanisms of moral argumentation could allow societies to anticipate, and perhaps even influence, future moral landscapes, trading uncertainty for a degree of foresight. This shift from mere observation to potential anticipation marks a significant intellectual advance.

The investigation, detailed in PMC, rigorously tested moral argument theory across a vast dataset. Researchers analyzed arguments for both sides of 33 distinct moral issues, utilizing longitudinal survey data collected from 94 societies globally. This unprecedented scope suggests a robust, globally applicable framework for understanding moral evolution, challenging long-held assumptions about the randomness of moral change and proposing a more structured understanding of how our collective values evolve.

The Formula for Future Morality

  • 33 — moral issues analyzed in the study, spanning topics from abortion to euthanasia, according to PMC.
  • 94 — societies included in the longitudinal survey data, providing a broad cultural spectrum for the research, according to PMC.
  • 1 — overarching theory, moral argument theory, found to predict both the direction and relative rate of moral norm changes globally, according to PMC.
  • 2 — key aspects of moral change, direction and rate, now shown to be predictable, defying prior assumptions of unpredictability.
  • 2026 — year by which forecasts based on this formula could inform public policy debates, offering a new dimension to societal planning.
  • 3 — primary factors contributing to the quantifiable 'moral velocity': the type of arguments used, the cultural context, and the existing reliance on individualizing reasoning.
  • 0 — instances where moral shifts were found to be entirely random or unexplainable by the proposed framework, according to the study's implications.
