The unequivocality of evidence in favor of unrealistic optimism has, however, recently been questioned. It is against this background that Nobel Laureate Daniel Kahneman described optimism as “the most significant of the cognitive biases” (p. Applied practitioners within health psychology, for example, have been concerned that if individuals perceive risks as more relevant to the average person than to themselves, individuals will not take appropriate protective behavior against major risks. Since Weinstein’s seminal paper, a huge number of academic papers (e.g., ) and popular psychological books (e.g., ) have expressed this view, ensuring its prevalence not only in social psychology, but also amongst applied practitioners and laypeople (e.g., ). These statements represent the dominant position in the literature. This unbridled optimism often leads couples to forego prenuptial agreements, which could offer the opportunity for more vulnerable halves of couples to protect themselves.People tend to think they are invulnerable and that bad things will happen to others, not to them.
The question of the official institution of marriage notwithstanding, libertarian paternalism offers new ways of looking at the old rules of people’s attachments to each other.Īs we learned in Chapter 1, most people know that 50% of marriages end in divorce, yet nearly 0% of newlyweds think theirs will. Despite the widely known health risks, smokers tend to believe that they’re less likely to get lung cancer than nonsmokers, and gay men systematically underestimate their likelihood of contracting AIDS. Where unrealistic optimism becomes problematic is, for example, in the areas of personal health.
UNREALISTIC OPTIMISM EXAMPLE DRIVERS
Ninety percent of drivers believe their driving skills are above-average 94% of professors at a large university believed they were above-average professors and most newlyweds believe their chances of divorcing are near zero (even though 50% of marriages end in divorce). Even though the students understand that only 10% of the class will be in the top decile and only 50% of the class will be in the top five deciles-these students are MBAs and get the basic math- typically less than 5% of the class believes its grade will fall below the median and more than 50% believes its final grade will fall in the top two deciles!Įxamples of this type abound. Before the class begins, Thaler has his students fill out a survey that invites them to predict in which decile their final grade for the course will fall. Thaler offers an example from his class in Managerial Decision Making. What Is Unrealistic Optimism?Įven when faced with the statistical likelihood of failure or mediocrity, individual humans persist-predictably-in believing themselves the exception to these statistics. Read more about unrealistic optimism and how it affects decisions. Even when probability indicates otherwise, people usually believe they’re the exception.
Unrealistic optimism is the way that people assume that things will work out in their favor. What is unrealistic optimism? Is it problematic?
