A method for inferring mental representations by successive comparison of items is disclosed. The method incorporates the steps of (a) presenting a series of N items to a participant; (b) asking the participant to compare each pair of items, where each item is compared with its immediate neighbour, except for the items at the two extremes which are compared to one another, so that each item is used in a pair twice, and N comparisons are done; (c) ordering the items by matrix iteration in order to obtain a new sequence of items; elaborating a new list of N/2 paired items, on the basis of immediate neighbours, taking each item only once; (e) asking the participant to compare each pair of items elaborated in step (d); (f) integrating the responses of steps (a) to (e) into a matrix; and (f) finally ordering the items based on the matrix obtained in step (f). The present invention is particularly useful for surveying purposes, among others.
