Although they may not intend to do so, observer bias may result in researchers subconsciously encouraging certain results, which ...
The observer-expectancy effect [a] is a form of reactivity in which a researcher's cognitive bias causes them to subconsciously influence the participants of an experiment.

Social science research is particularly prone to observer bias, so it is important in these fields to properly blind the researchers. In some cases, while blind experiments would be useful, they are impractical or unethical. Blinded data analysis can reduce bias, but is rarely used in social science research. [39]
Inherent in conducting observational research is the risk of observer bias influencing your study's results. The main observer biases to be wary of are expectancy effects.

Cross-sectional study: involves data collection from a population, or a representative subset, at one specific point in time. Longitudinal study: correlational research study that involves repeated observations of the same variables over long periods of time. Cohort study and Panel study are particular forms of longitudinal study.

[13] Conservatism bias, the tendency to insufficiently revise one's belief when presented with new evidence. [5] [14] [15]
In scientific research and psychotherapy, the subject-expectancy effect, is a form of reactivity that occurs when a research subject expects a given result and therefore unconsciously affects the outcome, or reports the expected result.
