The data input to the system includes the personal traits and personal preferences of individuals, including feelings, opinions, issues and purchasing or commercial preferences. A data correlating program provides data sorting parameters that are defined by selected degrees of human trait and preference variables.

Accordingly, discreet trait and preference specific groups of individuals that would be virtually impossible to locate and sample with typical focus group approaches are capable of being located and sampled with the present system and method.
