Decision-Making under Uncertainty: How Easterners and Westerners Think Differently

Abstract

It has long been known that Easterners exhibit more conservative attitudes, cautiousness behaviors, and self-control ability than Westerners; people in Eastern countries show stronger defensive reactions to societal threats than Western people. Are East Asians really risk averters or do some richer underlying preferences drive their behaviors in their decision-making under uncertainty? To answer this question, we examined the risk and ambiguity attitudes of East Asian populations in both gain and loss domains using classical behavioral economic experimental methods. Based on our sample of university students, we found that Easterners are more risk intolerant but more willing to accept ambiguous conditions than their Westerner counterparts in the gain domain. Perhaps surprisingly, Eastern people and Western people have a similar attitude toward risk and ambiguity in the loss domain. The higher level of risk aversion observed among East Asians may be due to the cultural difference between Western countries and Eastern countries. Historically, such risk aversion may make sense, because it would minimize the influence of numerous ecological and historical threats and socio-political practices. Our findings suggest that models that were designed to analyze and predict aggregate behaviors and markets may be ineffective for Eastern populations, and, in the future, it is of significance to develop appropriate representative agent models from the eastern perspective.

Evaluation of Health Science Students’ Health Fatalism and Perception Towards Patients With Epilepsy: A Cross-Sectional Global Study

“…This finding aids in interpreting the current study's findings and the fatalism assessment, especially among Muslim participants. The variation in views among different religious groups, especially easterners compared to westerners, can be attributed to the way of thinking under uncertainty which can be supported by the findings of Guo et al [55].…”

Suicidal ideation, perception of personal safety, and career regret among emergency medicine residents during the COVID‐19 pandemic

“…Although this finding requires additional investigation, prior work has demonstrated differences in risk and uncertainty tolerance between Asians and Whites, and COVID was a time of both high personal risk and uncertainty for physicians. 21 Additionally, the surge in anti-Asian racism, xenophobia, and violence that developed during the height of the pandemic may have contributed to increased personal risk concerns for Asian study participants. 22,23 Our survey question did not specify COVID risk concerns in terms of infection risk versus violence, and some respondents may have considered the latter risk of violence and harassment from patients and their families.…”

Do psychological distress and digital sports influence the willingness to take the vaccine and precautionary saving? Empirical evidence from Shanghai

“…Researchers claim that many substantial decisions are regularly made under uncertainty (Guo et al 2022 ). The uncertainty caused by COVID-19 is massive, including virus infectiousness, the time to accomplish vaccines, the possibility of new outbreaks, the duration of social distancing policy, the economic impact, the speed of economic recovery after the pandemic, changed saving and consumption behaviors (Altig et al 2020 ).…”
