COMMUNICATION AND INFORMATION PATTERNS AMONG NEW ORLEANS EVACUEES BEFORE, DURING AND AFTER HURRICANE KATRINA


Research by Dr. Susanna Priest

Persuading people to evacuate in advance of a predicted threat, such as a hurricane, has been a perennial problem that has resulted in the loss of many lives. Unfortunately, people tend to discount warnings, especially after repeated exposure to them. University of South Carolina researchers set out to learn more about the dynamics of these reactions.

USC researchers decided to investigate how much information – and from what kinds of sources – evacuees had about Hurricane Katrina before, during and after the storm and how this information fed into their decisions to stay in their homes or leave. In particular, USC researchers focused their efforts on the information that was received up to the moment a decision was made to evacuate.

The team interviewed more than 100 Katrina evacuees in four states (South Carolina, Louisiana, Texas, and Alabama) during the fall of 2005. The team relied on a network of faculty and graduate-student collaborators to reach the broadest possible range of interviewees. Researchers wanted to know whether gaps in knowledge led some people to delay evacuation and how these gaps might vary with ethnicity or social class.

Researchers also pursued additional issues, including the effects of media deprivation, the evaluation of media performance in this crisis, and the particular experiences of women and those returning to New Orleans. Researchers even explored the parallel between elements of disaster communication during Hurricane Katrina and those that might arise as the result of a terrorist attack. The team’s future analysis will look more closely at post-evacuation information needs and communication patterns.

Contrary to their expectations, USC researchers did not find strong evidence of knowledge gaps among different groups of people, although the level of trust in authorities was likely to have been a factor and might vary by social class and ethnicity. All in all, researchers concluded that both general hurricane knowledge and awareness of this particular storm were broadly distributed. Researchers also determined that knowledge and media warnings alone were often not enough to persuade people of the seriousness of the situation.

According to USC researchers, general knowledge of hurricanes and local knowledge of flooding vulnerability, interpersonal communication (such as alerts from neighbors, co-workers, or family members), and information from the media, especially the Category 5 designation, interacted in influencing evacuation decisions. In fact, for many evacuees, interpersonal communication and patterns of “opinion leadership” were crucial to a final decision to leave. Opinion leaders ranged from family members and neighbors to television appearances from the local weatherman or the mayor. Researchers found that in many cases it took a phone call or a neighbor knocking on the door to get people to make up their minds to move.

USC researchers were not the first to study the interaction of media information with preexisting knowledge and interpersonal communication. Research on other events has demonstrated that interpersonal communication is often more powerful than media messages, which are more easily discounted. This USC team concluded that media information was generally interpreted in discussion with other individuals. Social networks, they found, were therefore crucial to individual decision making in this context. The USC research team’s findings were also consistent with research literature in disaster sociology that argues that social networks do not easily deteriorate under this kind of stress. Rather, they remain cohesive and are an important source of community and family strength. Despite pervasive media images of looting and shooting, USC researchers found that most people in New Orleans were able to rely on such networks for support.

Researchers involved in this study are continuing their analysis to determine what factors best differentiate early and late evacuators. However, the researchers did walk away with some personal reflections from the study, which have broader impacts for society. For example, they discovered that the trauma associated with the sudden and total loss of one’s possessions (even in those cases where no one in the family has been injured or killed) is difficult, if not impossible, to imagine unless it has been experienced first-hand.

These researchers are also confident that this project has produced a new understanding of communication dynamics in the wake of disaster. The team, over half of which were women, included one African-American faculty member, one Asian-American faculty member and one African-American graduate student. They hope to improve disaster communication so that response to future disasters – whether natural or willful in origin – can be improved. This project helped build the team-based, quick-response research capacity of USC’s College of Mass Communications and Information Studies and strengthened its collaborative relationships with other institutions.

So far, this USC team has submitted a panel proposal to the National Communication Association and a manuscript to the Journal of Applied Communication Research. A number of other papers are also in progress, including one on media use before, during, and after the storm, as well as one on media deprivation. Research leader Dr. Susanna Priest will participate in a workshop on this topic at the Association for Education in Journalism and Mass Communication annual meeting.
