Free choice profiling

Free-choice profiling is a method for determining the quality of a thing by having a large number of subjects experience (view, taste, read, etc.) it and then allowing them to describe the thing in their own words, as opposed to posing them a set of "yes-no-maybe" questions. All of the descriptions are then analyzed to determine a "consensus configuration" of qualities, usually through Generalized Procrustes analysis (GPA) or Multiple factor analysis (MFA).

Dr Françoise Wemelsfelder is a well known scientist who has done extensive research in this field.
