An indication of relevant information impacting a change in opinion or conclusion for a given issue is derived using questionnaires while providing pertinent discussion materials and forums. A randomly selected group from a population (32) is polled to collect a range of opinions on a given topic (34), and then selectively exposed to material pertinent to the topic to improve group topic knowledge (36). Another group composed of volunteers from the population (46) is also initially polled (48) and selectively exposed to topic-pertinent materials (52). Both groups discuss or deliberate about the given topic (38, 50), and are subsequently polled (40, 54). Changes in opinions or conclusions are correlated to the selection of material to which the group was exposed (42, 56). By obtaining a correlation to topical materials, an impact of particular items in the materials can be measured for specific responses by either group. |
