The scientific method can be used

The scientific method can be used both in the physical sciences and in the social sciences.

Restricting it to physics and chemistry alone denies its proven use in social enquiry.

Restricting it to the social sciences alone ignores its origin in the natural sciences.

Limiting it to qualitative studies is wrong, since it underpins quantitative work as well.

The method rests on observation, hypothesis, testing, and verifiable conclusions.

Its shared logic is what lets both domains build cumulative, checkable knowledge.
