F Harris, Benjamin B. Lahey,

Reliability and Agreement in Measurement

Observational data may be recorded inaccurately due to several factors. They include expectation bias, effects of agreement checking, coding system complexity, behavior predictability, behavior valence, influence of extraneous cues, differential coder training, observer cheating, and differential observational media. The relevant work was reviewed and methods for minimizing each type of bias were discussed.
