How can researcher bias affect an intervention study's final results?
A researcher can inadvertently influence a study's outcome simply by knowing which subjects received an actual treatment and which received a placebo. This is a type of researcher bias. For example, if a researcher knows that certain participants received a treatment thought to improve memory, he might unconsciously score a memory test more favorably for those individuals. Because this type of bias may affect a study's final results, it should be avoided at all costs.
