na-adjective
empirical; evidence-based
Describes an approach, method, or attitude that relies on observation, experiment, or concrete evidence rather than theory or speculation. Often used in academic, scientific, and philosophical contexts.
実証的なデータに基づいて政策を立案すべきだ。
Policies should be formulated based on empirical data.
彼の研究
His research is highly regarded for its empirical methodology.
経験的 means 'experiential' or 'based on personal experience', which is less systematic than 実証的, which implies a more rigorous, evidence-based approach.
Compound of 実証 (jisshō, 'actual proof' or 'demonstration') and the adjectival suffix 的 (-teki, '-like' or '-ic'). The term is a modern coinage used primarily in academic and scientific discourse.
