What can observer bias impact during the observation process?

Observer bias can significantly impact the reliability of collected data during the observation process. When an observer has preconceived notions or personal experiences that influence their observations, the data gathered may reflect those biases rather than an accurate account of the situation. This can lead to skewed interpretations and conclusions, thus undermining the validity of the research or assessment. Reliable data requires an objective perspective; when bias enters the equation, the integrity of the results is compromised, making it difficult to draw sound conclusions and inform decisions effectively.

In contrast, while the comfort of the client, ethical considerations, and duration of the observation are all important aspects, they are less directly impacted by observer bias. The client’s comfort level may relate more to the setting and interaction style than to how observations are made. Ethical considerations often depend on protocols and standards that guide the observer's conduct, rather than personal biases. Lastly, the duration of the observation is typically determined by the requirements of the study or assessment framework, not directly influenced by the observer's biases.
