An important question in cogntive and evolutionary psychology is how the human mind anticipates the future and copes with stress and risk of disease. The parasite-stress model suggests that many patterns of human behavior and thought are adaptations to varying levels of exposure to parasites and pathogens. A growing body of health psychology research shows a link between positive future thinking and resiliency to various forms of disease. In this study, we investigate the link between historical pathogen prevalence in countries and individuals' perception of the future of humanity. We surveyed 18,981 participants across 68 nations, examining their beliefs about how well humanity will be doing 1000 years from now compared to the present. We found that individuals residing in regions with higher historical disease risk tend to have more positive views about the future of humanity than individuals residing in areas with lower historical disease risk. The difference could not be attributed to several other stress-inducing factors, such as climate stress, population density or objective or subjective socioeconomic indicators. This research contributes to a growing body of evidence demonstrating how disease risk shapes human cognition and encourages future exploration of the evolution of temporal forecasting and consciousness.
