Summary
Personality traits like extraversion and neuroticism influence disaster preparedness. Understanding these traits can help promote essential food stockpiling behaviors for future emergencies.
Area of Science:
- Disaster preparedness and risk management
- Psychological science and behavioral economics
Background:
- Food security is a critical concern during large-scale disasters.
- The Nankai Trough Earthquake poses a significant risk of food shortages.
- Individual psychological factors may influence disaster preparedness behaviors such as food stockpiling.
Purpose of the Study:
- To investigate the association between the Big Five personality traits and food stockpiling behaviors.
- To identify personality factors that can be leveraged to promote disaster food stockpiling.
Main Methods:
- A web-based survey was conducted with 1,200 participants in predicted high-risk areas.
- The Japanese version of the Ten-Item Personality Inventory (TIPI-J) was used to assess the Big Five personality traits.
- Mann-Whitney tests and multivariable logistic regression analyses were performed to analyze the data.
Main Results:
- No significant association was found between the Big Five personality traits and overall food stockpiling status.
- High extraversion was positively associated with initiating food stockpiling behavior.
- High neuroticism was positively associated with interrupted food stockpiling behavior.
Conclusions:
- While overall stockpiling is not directly linked to personality, specific traits influence different stages of the behavior.
- Targeting individuals with low extraversion and high neuroticism may be key to promoting effective food stockpiling strategies.
- Psychological insights are crucial for enhancing community resilience and disaster readiness.

Human fear responses to certain stimuli, such as darkness, heights, deep water, and blood, can often arise despite the absence of direct negative experiences. This phenomenon is rooted in evolutionary psychology, which posits that humans have developed a predisposition to fear stimuli that historically posed significant survival threats. This predisposition, known as preparedness, suggests that early humans who developed a fear of potentially dangerous entities, such as venomous snakes and...

Personality traits represent consistent patterns in behavior, thoughts, and emotions, reflecting an individual's tendencies across various situations.

These traits are stable over time, offering a reliable framework for predicting how people might act in different contexts. However, they do not define every moment of an individual's life. In contrast to traits,...

According to some social psychologists, people tend to overemphasize internal factors as explanations—or attributions—for the behavior of other people. They tend to assume that the behavior of another person is a trait of that person, and to underestimate the power of the situation on the behavior of others. They tend to fail to recognize when the behavior of another is due to situational variables, and thus to the person’s state. This erroneous assumption is...

Hans and Sybil Eysenck developed a widely recognized theory of personality, which emphasizes the role of temperament and genetically based differences in shaping individual traits. Their theory posits that biological factors primarily determine personality and can be understood through two main dimensions: extroversion/introversion and neuroticism/stability.
In the extroversion/introversion dimension, highly extroverted people are sociable, outgoing, and easily connect with others. In contrast,...
