Final answer:
Behavior analysts aim for greater than 90% agreement between multiple independent observers when recording behavior to ensure high inter-rater reliability and counteract observer bias.
Step-by-step explanation:
When recording behavior, behavior analysts strive for greater than 90% agreement between multiple independent observers. Achieving high inter-rater reliability is crucial to ensure that the observations are consistent and reliable, and to protect against observer bias. Observer bias refers to the unintentional skewing of data to fit expected results by an observer. To counteract this, clear criteria for behavior recording is established. Although achieving 100% agreement would be ideal, it is often unattainable due to the variability in human judgment, hence 90% or greater is the standard in behavior analysis research.
