Optimistic bias is a mistaken belief that one’s chances of experiencing a positive event and outcome are higher than those of the peers. According to Tali Sharot’s experiments, research and findings in the cognitive science have contributed and facilitate the increased understanding of the biological basis of optimism. Optimism bias is grounded in our setting in which we tend to think of the positive feedback and outcome as well as desirable changes that are likely to arise depending on our culture and setting (Sharot, 2012). Culture is the peoples' way of life that is shared and includes the ideas and the traditions; it contains all the aspects of the values, beliefs, and influences the viewpoints, rules and institutions in the individual setting. The culture has a close correlation with the individuals thinking and reasoning process that tend to build our optimistic bias.
