The key advantage of using observation as a method of information gathering is its ability to verify data collected through other methods. Observation allows the researcher or designer to directly witness behaviors, interactions, and environments, providing an objective perspective that can confirm or clarify findings obtained from surveys, interviews, or self-reported data. This validation process is crucial in ensuring that the information is accurate and comprehensive, reducing the risk of drawing conclusions based solely on potentially biased or incomplete self-reports. Observational methods capture context and nuances that might be missed in verbal accounts, hence strengthening the reliability of the overall research.

Other options, while they contain elements related to gathering information, do not capture the primary benefit of observation as effectively as the ability to verify data. For instance, immediate feedback from participants often pertains more to interactive methods, while verbal communication accounts are not the focus of observational techniques. Moreover, while observation can minimize certain biases, it does not entirely eliminate them, particularly those related to the observer's interpretations or perspectives.
