Most effective disaster risk communication practices are based on the equitable distribution of crisis messages to the target population. Priority is given, for example, to conveying evacuation messages to as many people as possible using language and media appropriate to that audience. Cognitive dissonance (CD) studies, however, show that well-intentioned disaster management messages can not only generate unintended public reactions, but can also strengthen public sentiment to reject or reject the essages themselves. A review of the literature focused on the effects of gnitive dissonance on communication, disaster management will yield two tcomes. First, a re-search will show that a basic understanding of CD can p disaster communicators create more effective messages and, second, it introduce an early cognitive dissonance index (CDI) that can be easily orporated into existing crisis communication models. This "upgrade" to the ting risk communication framework is an efficient method of closing the loop from theory to practice and starting to take into account the power of CD in our national and international disaster communications Communication; Disaster management, risk analysis, crisis communication, cognitive dissonance
