“For example, suppose a group of elementary schoolchildren were given the job of trying to find out what was happening to America since color TV. Teams of them could be turned loose in just making inventories of effects observable in clothing, in food, in cars, in designs, in family life, in all sorts of forms. If they merely made inventories, they didn’t have to use any ideas, they didn’t have to reach any conclusions, they merely were invited to observe, to make inventories of effects. Small children love this kind of work, and are just as able researchers as any team of sociologists in the world. And the accumulation of such inventories can be absolutely necessary and indispensable to the highest operations.”
