mirror research. A disadvantage is observation bias when observers see what they expect to see. In order to avoid this one can use blind observers, this is people who has no idea what in the research they should actually see, and what the research question is. Naturalistic observation is good if the observer wants the participants to react normally, but the only problem is that this is time consumuning. There is also no control on what will happen in the environment and it is unpredictable to know if the observer will be completely unbiased.
