What principle emphasizes the importance of brevity in testimony?

The principle that emphasizes the importance of brevity in testimony is best represented by objectivity. When providing testimony in a legal context, it is crucial to remain focused on the facts without extraneous detail or subjective interpretation. Objectivity promotes a clear and concise presentation of information, which is vital for maintaining the integrity of the testimony and ensuring that the message is understood by the audience, such as jurors or judges. By prioritizing brevity, a witness can enhance the clarity of their testimony, reducing the risk of confusion or misinterpretation while remaining impartial and factual throughout the process.
