A method of generating and evaluating feedback from a plurality of respondents requests associations from the respondents to a given subject item description. The associations may be given as selections from a list of associations given by previous respondents or as free input. An evolutionary algorithm maintains the list of associations from which the respondents may select. Associations that are selected by subsequent respondents are promoted in the list and those not selected dropped.
