Empirically

Empirically is an adverb describing action done through or based on observation, experience, or experiment rather than theory alone. In science, scholarship, and everyday language, statements are described as being supported empirically when they are grounded in data collected from the real world. The term is often contrasted with explanations that rely solely on logic, tradition, or speculation.

In empirical research, investigators gather measurements, observations, or experimental results and analyze them to draw conclusions that can be tested and replicated. Methods include controlled experiments, observational studies, surveys, and case studies. The strength of an empirical claim rests on the quality of the data, the appropriateness of the methods, replication, and transparent reporting. Empirical findings support, modify, or refute hypotheses but rarely establish certainty, given uncertainties, biases, and generalizability concerns.

Etymology and philosophy: the word derives from Latin empiricus, from Greek empeirikos, meaning experienced. In philosophy, empiricism is the view that knowledge arises from sensory experience. Empirically derived conclusions are provisional and subject to revision with new evidence. In practice, statements are described as empirically verified or supported when they have been demonstrated through observation or experiment. The term is widely used across disciplines, including medicine, psychology, economics, and the social sciences, to indicate that claims are tied to observed data rather than abstract speculation.
