Demand characteristics tend to describe attitudes or behaviors on the part of the subject, who is (often implicitly) trying to figure out the point of a study and give the researcher what s/he wants. Phenomenological inquiry involves the researcher being upfront and honest with the subject with respect to what the researcher is seeking. Suppose a mixed-methods experiment is done, and an interview based on phenomenological inquiry is done after dependent variable data is collected, might it be a good way to figure out whether the participant was trying his/her best to please the experimenter?
