The frequently-raised objection when it comes to quality research, UX research included, is that the conclusions are drawn based on the participants’ declarations. However, there exist some methods which allow one to grasp the real behaviors of participants, and they can be easily implemented into the research scenario.
During exploratory research, the respondents are often unable to articulate their needs or opinions. In turn, when it comes to usability tests or satisfaction surveys, it very often happens that the respondents’ answers are limited to vague opinions which, without being further explored by the moderator, don’t bring in much data.
Very often, they hide their opinions, because something is “not quite right” to say, something makes them feel ashamed, or their behaviors are controlled by mechanisms which they don’t even perceive—because who would admit to having certain prejudices or not fully socially-accepted desires?
Then how does one find out the real opinions of respondents?
