Final answer:
The belief that men are inherently more rational and therefore better leaders aligns with the Structural Functionalism sociological perspective, which sees society as a complex system with roles based on stable patterns.
Step-by-step explanation:
When one thinks that men are better leaders because they are more rational, they are adhering to Structural Functionalism. This perspective tends to see society as a complex system whose parts work together to promote solidarity and stability. The idea that certain roles, like leadership, are suited to a particular gender based on assumed inherent qualities, such as rationality, reflects functionalist views on the division of labor and societal roles.
