Sociology can answer the how questions rather than the why questions favoured by psychology for example. It is less likely to blame the individual but rather looks at the underlaying social structures in place.
Sociology is a science that aggregates the elements of society. This helps us understand human living as a group/ community/ a set of people within a geographical border/ conceptual boundaries.
Knowing this subsequently helps structure problems and solutions, studying weak points and strengths. It drives to put the resources together and splits the damages into segments to repair social issues. Sociology aids in strategizing a better way of living for humans.
