What is substrata factor theory by Jack Holmes?

Substrata Factor Theory, proposed by Jack Holmes, posits that the underlying factors influencing social behavior and attitudes are shaped by the substrata—fundamental cultural, economic, and social conditions of a society. This theory suggests that these substrata interact with individual and group dynamics, ultimately affecting how people perceive and respond to various social phenomena. By analyzing these foundational layers, Holmes seeks to explain variations in behavior across different contexts and populations, emphasizing the importance of understanding the broader societal influences on individual actions.
