Winnowing

Winnowing is the process of separating grain from chaff or other unwanted material by using wind or a current of air. Figuratively, it refers to the act of separating the valuable or desirable elements from the less valuable or undesirable ones, often through careful examination or scrutiny. This sifting process can apply to ideas, information, people, or any set of things where one seeks to identify and retain the best or most relevant parts, while discarding the rest. The goal is to refine and improve the quality or clarity of something. It can involve both physical processes and abstract, analytical thought.
