In 1973, a seminal work was published that would forever change the way we understand human values.

This comprehensive study not only shed light on the complexities of human values but also provided a framework for understanding their significance in shaping our behavior, attitudes, and interactions with others.

Measurement and Methodology One of Rokeach’s most significant contributions is operationalizing values for empirical study.

This forced-ranking method yields an ordinal value profile, allowing comparisons across individuals, groups, and cultures. Rokeach defends ranking as superior to rating because ranking reveals priorities and trade-offs more clearly. He supplements the RVS with behavioral observations, experimental manipulations (e.g., cognitive dissonance paradigms), and analyses of value change, providing a multifaceted methodological program to study values empirically.

A landmark contribution is the for value change:

These represent the ultimate goals or "ends" an individual hopes to achieve during their lifetime.
