Soft science is a colloquial term, often used for academicresearch or scholarship which is purportedly "scientific" however it is not based on reproducible experimental data, and/or a mathematical explanation of that data. The term is usually used as a contrast to hard science.Within the natural sciences, research which depends upon conjecture (sometimes called hypothesis), qualitative analysis of data (compared to quantitative analysis), or uncertain experimental results is sometimes derided as soft science. Examples are evolutionary psychology or meteorology. When soft science refers to a natural science, it is usually used pejoratively, mainly due to the term's association with social science, implying that a particular natural science topic described as "soft" does not belong to the field of natural science.
