Descriptive Science

The term descriptive science is used to identify a category of science and distinguish it from other categories of science. The exact demarcation line can vary a bit depending on the purpose of making the distinction, but essentially it refers to those parts of science whose emphasis lies in accurate repeatable descriptions such as:

X causes A in circumstances B.

Niiniluoto suggests that the distinction between what he calls descriptive sciences and design sciences is fundamental. "Descriptive sciences primarily aim to describe, explain and understand the reality surrounding us. Design sciences, on the other hand, aim at knowledge that is useful for the activity of design, i.e. aim to enhance human art and skill."

David A. Grimaldi and Michael S. Engel suggest that descriptive science in biology is currently undervalued and misunderstood. "“Descriptive” in science is a pejorative, almost always preceded by “merely,” and typically applied to the array of classical -ologies and -omies: anatomy, archaeology, astronomy, embryology, morphology, paleontology, taxonomy, botany, cartography, stratigraphy, and the various disciplines of zoology, to name a few. First, an organism, object, or substance is not described in a vacuum, but rather in comparison with other organisms, objects, and substances. Second, descriptive science is not necessarily low-tech science, and high tech is not necessarily better. Finally, a theory is only as good as what it explains and the evidence (i.e., descriptions) that supports it."

"ll researchers interpret the world through some sort of conceptual lens formed by their beliefs, previous experiences, existing knowledge, assumptions about the world and theories about knowledge and how it is accrued. The researcher’s conceptual lens acts as a filter: the importance placed on the huge range of observations made in the field (choosing to record or note some observations and not others, for example) is partly determined by this filter"-Carroll and Swatman
