In addition to optimistic bias which can be a biased phenomenon in perceived susceptibility, including illusion of control which is a distorted phenomenon, the current study attempted to demonstrate the influential relationship between these two important variables and COVID 19 personal preventive behaviors and social distancing practice. Conducting Survey utilizing online pannel from Macromill Embrain, the present study performed regression analysis, setting personal preventive behavioral variables such as mask wearing, hand washing, using hand sanitizer as independent variable, and analyzed how these independent variables influence control illusion and optimistic bias. As a result, COVID 19 personal preventive behavior didn't have direct effect on optimistic bias and control illusion except for hand washing. Finding, also, showed that control illusion affected optimistic bias, and the relation between these variables was different depending on demographic variable such as gender and age.

The present study aims to investigate the sequential mediation model in the relationships between optimistic bias, subjective perception, risk perception, and the future time perspective in terms of a particulate matter and depression, using the sequential mediation model. An online self-reported survey was conducted on 545 participants who agreed to participate in the current study. We considered depression as a dependent variable, optimistic bias as an independent variable, and subjective perception of particulate matter, the risk perception of particulate matter, future-time-perspective as mediators. The sequential mediation analysis was conducted using the SPSS Macro. The results show that optimistic bias was not directly related to depression, but was related to indirect paths through the subjective perception of particulate matter, the risk perception of particulate matter, and future time perspective. More specifically, the lack of optimistic bias was related to a tendency to subjectively perceive the quality of air pollution more seriously and a limited future time perspective, which subsequently related to depression. Future studies should pay more attention to the effects of particulate matter on the quality of life and mental health.

In the acceptance of new technology products, not only the characteristics of the product itself, but also the consumer's psychological perception of the product has a great influence. This study analyzed the effects of psychological variables such as perceived risk, technology trust, and optimistic bias on consumers' intention to accept new technology products. This study selected nanotechnology, and we found consumers with high perceived risk showed relatively low intent to accept nanotechnology products compared to consumers with high perceived risk. However, in case of high level of technology trust, consumers with high perceived risk did not show any significant difference in the intention to accept nanotechnology products. We also found that such moderating effect of technology trust is mediated by optimistic bias. We hope that the findings of this study can give meaningful implications to nanotechnology developers, marketers, and policy makers in nanotechnology industry.

시스템 다이내믹스는 인과지도(Causal map)를 통한 시스템 이해를 그 출발점으로 한다. 특히 시스템 사고(systems thinking)는 저량-유량 흐름도를 통한 컴퓨터 시뮬레이션을 통하지 않고서 인과지도 분석만을 통한 시스템의 이해를 시도한다. 그러나 과연 인파지도만을 가지고 시스템을 동태적 변화를 이해/예측할 수 있는가에 관하여는 낙관적 전망과 부정적 전망이 혼재되어 있는 상황이다. 본 연구에서는 인과지도 구축을 통하여 시스템의 변화를 이해하는 데 있어서 어떠한 인지적 편향(bias)이 개입되는지를 탐색하고자 한다. 만일 심리적 편향이 존재한다면. 시스템 사고는 오류로부터 자유로울 수 없을 것이다. 본 연구에서는 이러한 오류의 존재를 탐색함으로써 시스템 사고의 제한정과 그 극복방안에 관하여 논의하고자 한다.(중략)

This study examined the linkage between positive cognitive bias and entrepreneurial intention. Self-enhancement, unrealistic optimism, and illusion of control have been collectively referred as positive cognitive bias. We examined the effects of positive cognitive bias on attitudes toward success and failure. And we also examined the effect of attitudes toward success and failure on entrepreneurial intension. This study investigated these relationships using 240 high school students. The result of analysis indicated that the self-enhancement bias and unrealistic optimism bias had positive effects on attitude toward failure, but it had not any effect on attitude toward success. The illusion of control bias has positive effects on attitude toward success, but it had not any effect on attitude toward failure. The attitudes toward success and failure had positive effect on entrepreneurial intension. Then results of this study suggests that the cognitive biases showed a role of antecedents of attitudes toward success and failure. Finally, this study concluded with a discussion of the implications of the research findings and directions for future research.

Entrepreneurial self-efficacy is an important variable that explains people's attitudes and behaviors toward start-ups. In this study, we focused on individual psychological characteristics variables such as luck in belief and positive cognitive bias that affect entrepreneurial self-efficacy. Among these variables, we paid particular attention to luck in belief. The belief that business success depends on luck is widespread, but scientific verification about it has not been much. The reason for the academic indifference is that luck is a kind of superstition, related to precognition or extrasensory perception, and randomly caused by the external environment. The study of luck began in earnest as a measure to measure luck as an individual characteristic variable such as personality was developed. The purpose of this study is to examine the existing studies on luck in belief and to examine the effect of this luck in belief on positive cognitive bias and entrepreneurial self-efficacy through empirical analysis. For empirical analysis, this study conducted an on-line survey of 400 ordinary people and conducted a structural equation model analysis using AMOS 21.0 to verify the hypothesis. As a result of hypothesis testing, all hypotheses that luck in belief would have a positive effect on positive cognitive bias(self-enhancement bias, illusion of control bias, unrealism optimistic bias) were adopted. The hypothesis that positive cognitive bias(self-enhancement bias, illusion of control bias, unrealistic optimism bias) will have a positive effect on entrepreneurial self-efficacy was also adopted. Additional analysis was conducted to examine the mediating role of positive cognitive bias in the relationship between luck in belief and entrepreneurial self-efficacy, which showed that 'luck in belief→positive cognitive bias →entrepreneurial self-efficacy' were statistically significant. Through this, we confirmed the mediating effect of positive cognitive bias in the relationship between luck in belief and entrepreneurial self-efficacy. In the conclusion, the implications and limitations of the study were presented based on the results of this study.

Many studies in the field of information security reveal the need to increase awareness. However, although awareness of information security has been raised to a considerable extent, actual security behavior has been shown to fall short of that. Therefore, we wanted to identify the role of psychological factors in making information security decisions by conducting a experimental study. The results show that there are differences in perception of information security risks according to the probabilistic distance and the degree of relative optimism due to social distance. In relation to their relative optimism and intention of information security, they reduced the level of perceived risk compared to those close to them and found that their influence varied according to their probabilistic distance. This study has made valuable attempt in terms of methodology and it is meaningful that the psychological factor is taken into consideration for the information protection behavior, so that the range of relative optimism that actually affects the perception of risk is narrowed. It is expected to contribute to the improvement of information security level of information technology users and protection of information assets by empirically identifying necessity of various approaches to decision making process for information security.

The purpose of this study was to identify nursing students' knowledge, attitudes, and optimism bias about cancer, and the degree of national cancer prevention health behavior and to identify factors affecting cancer prevention behaviors. The data were collected from June 3 to June 28, 2020 for 241 nursing college students at J-C University. As a result of the study, nursing students' knowledge of cancer was 23.28±5.62 points, attitude was 40.33±8.15 points, optimistic bias was -.13±1.48 points, and national cancer prevention health behavior was 3.47±.59 points. National cancer prevention health behaviors of nursing students correlated with knowledge, attitudes, and optimistic biases on cancer. Among them, variables affecting cancer prevention health behaviors are attitudes toward cancer and optimism bias, which is 37.0 %. Therefore, it is necessary to develop a program to increase attitudes toward cancer and reduce optimism, and to practice cancer prevention health behaviors by reducing biases through positive attitudes and awareness of the importance of health behaviors through systematic and continuous education.

Recently, various risks of smartphone hacking are emerging. Smishing crime techniques become more cunning and its damage has been increasing, thereby requiring effective ways of preventing and coping with smishing. Especially, it is emphasized the need for smartphone users' security awareness and training besides technological approach. This study investigates the effective method for providing news messages in order to improve the perception of risk from smishing. This research empirically examines that the degree of optimistic bias on risk perception can vary depending on news frame, topic type, and involvement regarding smishing. Based on the findings, it identifies the factors influencing risk perception and verifies effective ways of promoting individual security awareness on smishing. The results of this study provide implications that assist in educating, campaigning and promoting information security awareness for smart device users.

Despite increasing damages caused by violations of COVID-19 precautions, studies on violations of precautions have not yet received much attention. This study identified antecedents that could theoretically influence the intention to violate COVID-19 precautions based on the black swan theory, and collected 215 responses by conducting an online survey from February 11, 2021 to March 10, 2021. As a result of the regression analysis, this study found that dissonance with COVID-19 preventive information, representativeness bias, and availability bias increase the intention to violate COVID-19 precautions. However, optimistic bias did not have a significant effect on the intention to violate precautions. This study not only provides new antecedents but also suggests theoretical evidence for decreasing intention to violate precautions. This study also proposes the necessity to identify differences in violation intention by regions, countries, and theories.
