Most of this study has been devoted to establishing the facts on the information and attitudes that were present and how they were distrib uted among the population. We have examined who believed and who said what. The sources from which they acquired such information have often been a matter in which we have relied on inference, the effects of it almost always so. As we now sum up our conclusions, it is to these inferences that we turn. We wish in the closing pages not so much to review the facts as to take note of patterns in the effects of communica tions and most particularly of those patterns which probably apply wherever men are reaching national decisions under the impact of per suasive messages from a multitude of global sources.
