People who either suffer from some disability or belong to ethnic minorities, such as African Americans and Latinos, are more susceptible to terrorism-related fears than others, according to a new study.
University of California-Los Angeles (UCLA) researchers have found that such people make more behavioural changes based on terrorism-related fears, such as avoiding certain activities, than others.
Revealing their findings in the American Journal of Public Health, the researchers say that these groups also tend to overestimate the threat of terrorism, perceiving the risk as high even when the U.S. Homeland Security Advisory System's (HSAS) colour-coded alert system rates it lower.
"Just like natural disasters have been shown to affect certain groups of people more than others, we're now seeing evidence that terrorism fears are having a disproportionate effect on some of our most vulnerable groups," said leady study author David P. Eisenman, assistant professor of medicine in the division of general internal medicine and health services research at the David Geffen School of Medicine at UCLA.
"It's important for the public to know this because it shows that terrorism's intention to induce fear and change does work - on the most vulnerable. Terrorism affects these groups even when there has not been an event in a long time.
"It also shows," he added, "that the HSAS color-coding is misjudged by citizens, and the same persons who have the most fear and avoid activities are also misjudging it," he added.
