A filter question is a carefully crafted inquiry designed to sift through information and narrow down options in order to reach a specific outcome or decision. It acts as a sieve, separating relevant and useful data from irrelevant or unnecessary details. This type of question is often used in research, surveys, and decision-making processes to streamline and focus the flow of information. By strategically filtering out extraneous information, a filter question helps to clarify and simplify complex situations, making it a valuable tool for critical thinking and problem-solving.
