World views were postulated in the 1960s as five value orientations which are universal human existential issues to which individuals from different cultural backgrounds may have different solutions. While the Kluchhohn and Strodtbeck framework has made a significant contribution towards measuring cultural differences, it has limitations for studying within-group and between-group patterns of cultural similarities and differences. This paper presents theoretical speculations as well as research findings using worldviews as cultural and psychological variables for cross-cultural comparisons. It reviews selected worldview studies and attempts to find valid information from inconsistent comparative data via traditional scientific rationality. Its findings suggest that background factors affecting worldview are gender, religion, education, marital status, and modernity. It concludes that what can be of benefit from the research findings may not be what is present in one particular study, but the synthesis of variations of cultural patterns over time and a comparison of changing patterns across groups. The paper presents one table outlining research findings of worldview differences and one table outlining research findings of worldview differences. (Contains 31 references.) (JDM)
