Optimism Bias | Vibepedia

Optimism bias is a cognitive bias that leads individuals to overestimate the likelihood of positive events and underestimate that of negative events, with implications for decision-making, public health, policy, economics, and law. This bias is common across cultures, genders, ethnicities, nationalities, and age groups, and is influenced by factors such as mood, desired end state, and cognitive mechanisms. As noted by experts like Daniel Kahneman and Amos Tversky, optimism bias can have significant effects on individual and group decision-making, and has been studied in relation to various fields, including psychology, economics, and public health, with researchers like Tali Sharot and Timothy Wilson contributing to our understanding of this phenomenon.
