Why do researchers use deception?

Subject deception is typically used to promote scientific validity, with subjects provided with false or incomplete information about the research in order to obtain unbiased data with respect to the subjects’ attitudes and behavior when complete or truthful disclosure is expected to produce biased results.

What is an operational definition in an experiment?

An operational definition of a variable is the set of procedures used to measure or manipulate it. A good operational definition is clear enough so that an independent researcher could use the same procedure (replicate the research) and get the same results.
