The expression describes the state of discovering information previously unknown to the speaker. For example, upon learning about a recent policy change affecting business operations, an individual might remark that the development was previously unfamiliar.
The value of acknowledging previously unknown information lies in promoting transparency and fostering a culture of continuous learning. Recognizing gaps in knowledge allows for targeted efforts to improve understanding and avoid potential errors stemming from outdated or incomplete information. Historically, admitting a lack of awareness has been crucial for adapting to evolving circumstances across diverse fields, from scientific discovery to organizational management.
