Final answer:
Projectivism, a theory within the social sciences, can explain the ban on mixed worlds by stressing the importance of context-specific analysis within modernist projects. It suggests that values and meanings are not inherent but are projected by individuals, thus mixed worlds could potentially lead to confusion or misinterpretation of specific contexts.
Step-by-step explanation:
The concept of projectivism in the context of modernist projects helps explain the tendency to avoid 'mixed worlds' by emphasizing the importance of specificity and local context in understanding social phenomena. The modernist project, in social sciences, aims to address complex questions by narrowing down the 'where' before addressing the 'why'. It suggests that by understanding the particular context of a situation, researchers can better comprehend and explain the social and cultural dynamics at play.
Projectivism posits that values and meanings are not inherent in the world but are projected onto it by human minds. In this sense, a ban on 'mixed worlds'—that is, theory or practice that combines multiple, possibly disparate contexts—might be understood as an attempt to maintain the integrity and clarity of specific projects or theories that are rooted in particular contexts. This consideration ensures that the uniqueness of a subject matter is respected and allows for more accurate and applicable interpretations and conclusions.
