Individual User-Derived Assessments of Earthquake Early Warning Systems
Does statistical evidence accompanied by messages of what the numbers imply impact perceived effectiveness of a measure for reducing disaster risk
Case information focusing on a particular person does not provide representative evidence on the risks or benefits for a given population. However, research on judgement and decision‐making has revealed that statistical information focusing on the population is much less influential on recipients than case information, as exemplified by the identifiable victim effect. On the other hand, studies on persuasion have reported that explanatory message…
Human behavioral response to earthquake early warnings (EEW)
When people are defeated by artificial intelligence in a competition task requiring logical thinking, how do they make causal attribution
The Effects of Earthquake Experience on Intentions to Respond to Earthquake Early Warnings
Warning systems are essential for providing people with information so they can take protective action in response to perils. Systems need to be human-centered, which requires an understanding of the context within which humans operate. Therefore, our research sought to understand the human context for Earthquake Early Warning (EEW) in Aotearoa New Zealand, a location where no comprehensive EEW system existed in 2019 when we did this study. We un…
A comparison of perceived effectiveness of preventive behaviors against Covid-19 between the public and medical experts
This brief report documents the results of a survey that measured the public's and doctors' perceived effectiveness of preventive behaviors against COVID-19, in Japan. Medical doctors ( n = 117) and the general public ( n = 1086) participated in our online survey. The results of the analysis of mean scores indicate that there were only slight differences in perceived effectiveness between the two groups, while the differences in distributions wer…
May risk communication with non-experts contribute to post-disaster restoration of normalcy? A survey on the disaster-struck prefectures after the Great East Japan Earthquake
Post-disaster risk communication's primary goal is to restore a sense of normalcy for residents who have faced hardships. The Fukushima and Miyagi prefectural residents who experienced severe damage from the Great East Japan Earthquake were the participants (men = 257, women = 296, age = 58.40 ± 14.85) of this study, which investigated a mediation model of effective risk communication on restoring a sense of normalcy. The characteristics of risk …
Earthquake early warning in Aotearoa New Zealand
Earthquake early warning (EEW) can be used to detect earthquakes and provide advanced notification of strong shaking, allowing pre-emptive actions to be taken that not only benefit infrastructure but reduce injuries and fatalities. Currently Aotearoa New Zealand does not have a nationwide EEW system, so a survey of the public was undertaken to understand whether EEW was considered useful and acceptable by the public, as well as perceptions of how…
When Descriptive Norms Backfire
This study aimed to examine the adverse effects of descriptive norms in the context of disaster preparation, although the cumulative evidence has demonstrated that descriptive norms desirably promote social behavior. Descriptive norms inevitably inform that some people do not prepare; therefore, the secondary meaning can be utilized to confirm the receiver's already possessed attitudes, and it results in a backfire. We conducted two preregistered…
The Effects of the Passage of Time from the 2011 Tohoku Earthquake on the Public’s Anxiety about a Variety of Hazards
This research investigated whether the Japanese people's anxiety about a variety of hazards, including earthquakes and nuclear accidents, has changed over time since the Tohoku Earthquake in 2011. Data from three nationwide surveys conducted in 2008, 2012, and 2015 were compared to see the change in societal levels of anxiety toward 51 types of hazards. The same two-phase stratified random sampling method was used to create the list of participan…
Public judgment on science expenditure in the national budget of Japan
How does the public assess an appropriate financial allocation to science promotion? This article empirically examined the subadditivity effect in the judgment of budgetary allocation. Results of the first experiment showed that the ratio of the national budget allocated for science promotion by participants increased when science was decomposed into more specific categories compared to when it was presented as “science promotion” alone. Consiste…
Public anxiety after the 2011 Tohoku earthquake
In 2011, Japan received a massive blow from the Tohoku Earthquake and the ensuing disaster at the Fukushima Dai-ichi Nuclear Power Generation Plant (hereafter, the Fukushima Nuclear Plant), with 18, 000 people dead or missing, and more than 330, 000 evacuated long-term. Anxiety among the people of Japan concerning earthquakes and nuclear accidents is higher than ever, but other hazards confront them as well. This research investigated whether the…
Trust in a High‐concern Risk Controversy
A community survey examined factors affecting the trust of four groups involved in a high concern controversy over the risks posed by motor boats to the quality of a municipal water supply. In an effort at conceptual integration the survey results were used to examine the relationships between three concepts of trust. Perceived agreement in values between self and four controversy‐involved groups was found to be the most powerful predictor of tru…
