Historical Perspective: Using the Past to Study the Present
解释历史视角如何帮助理解当前现象，避免误导性结论，并改善研究设计，适合社会科学研究者参考。
Historical perspective refers to understanding a subject in light of its earliest phases and subsequent evolution. This perspective differs from history because its object is to sharpen one's vision of the present, not the past. When historical perspective is overlooked in social research, researchers may draw misleading conclusions. Historical perspective expands research horizons by encouraging study of the relative stability of phenomena, providing alternative explanations for phenomena, and aiding problem formulation and research design.
