Final answer:
Duncan Watts discusses sociological research that involves complex social phenomena, which are challenging to inspect using strict scientific methods due to numerous variables and the potential for researcher bias.
Step-by-step explanation:
In the context of sociology, Duncan Watts discusses research that involves intricate and multifaceted social phenomena, which are often challenging to study using straightforward scientific methods. Sociological interviews, for example, need to avoid researcher bias and must handle a multitude of interacting variables that make simple categorization of responses difficult. Moreover, making a sociologist's presence 'invisible' in certain settings such as prisons or secretive organizations like the Ku Klux Klan is not always possible, thus limiting the feasibility of certain types of observational research. Sociological research often revolves around understanding social characteristics and their impact on various outcomes like community well-being, crime rates, and other societal trends. However, the inherent complexity of social systems and the potential for researcher bias make certain scientific approaches to sociology not always feasible.
