In this country we are fond of polling the public to find out what it thinks about practically any given subject. We have thousands of polls about foreign policy, and the public is ever ready to express attitudes on any question, no matter how complex, about which it might be asked. It is even ready, apparently, to express its convictions on problems which do not exist. One poller, for example, conducted a survey on the public attitude toward the “Metallic Metals Act.” He found that a good sixty percent of the public had an opinion about this act and a majority of them were in favor of it—even though the “act” existed only in the poller's imagination.
