Observatørskjevhet

Observatørskjevhet, or observer bias, is a systematic error that can occur in research when the observer's expectations or beliefs influence the data they collect. This bias can manifest in various ways, such as unconsciously interpreting ambiguous observations in a way that confirms their preconceived notions or selectively noticing and recording data that supports their hypothesis while ignoring contradictory evidence.

This phenomenon is particularly relevant in qualitative research, where subjective interpretations play a larger role. For example, a researcher studying children's play behavior might, if they expect certain types of aggression, be more likely to label a child's actions as aggressive even if they are objectively ambiguous. Similarly, in scientific experiments, if an observer expects a particular treatment to be effective, they might subtly influence the outcome by, for instance, treating the experimental group differently from the control group.

To mitigate observatørskjevhet, researchers often employ strategies such as blinding, where the observer is unaware of the experimental conditions or hypotheses. Using standardized observation protocols and multiple independent observers can also help to reduce the impact of individual biases. Clear definitions of what constitutes a particular behavior or observation are crucial in preventing subjective interpretations. Rigorous training for observers is also essential to ensure consistency and minimize personal influences on the data collection process. By acknowledging and actively addressing observatørskjevhet, researchers can enhance the reliability and validity of their findings.
