概要	IMRaD is the standard organizational framework for scientific manuscripts in biomedical and natural sciences research. It separates reporting into four sequential sections—Introduction (why the research was conducted), Methods (how it was done), Results (what was found), and Discussion (what the findings mean)—enabling readers to understand, evaluate, and reproduce the work. Adopted as best practice by the International Committee of Medical Journal Editors (ICMJE) since the 1970s, IMRaD structure is now mandated or strongly recommended by most peer-reviewed journals.	Clear scientific writing enables readers to understand methodology, results, and implications without confusion. Clarity is not ornamental—it is essential to scientific integrity. Unclear writing obscures findings, enables misinterpretation, wastes readers' time, and reduces impact and citations. Scientific clarity requires active voice (when appropriate), conciseness (eliminating redundancy), precise word choice (correct terminology), logical organization, and transparent reasoning. These principles apply across disciplines and are supported by style guides (APA, Vancouver), writing textbooks, and journal editors' expectations. Clear writing also helps authors think more precisely; the act of writing clearly often reveals gaps or inconsistencies in logic.
