Self-enhancement suggests that optimistic predictions are satisfying and that it feels good to think that positive events will happen. Those parts of the brain are activated to regulate emotional regulation. Here are a few examples of optimism bias: Expecting you won't have a car wreck, despite others you know have been in wrecks. In a study where participants believed their driving skills would be either tested in either real-life or driving simulations, people who believed they were to be tested had less optimistic bias and were more modest about their skills than individuals who would not be tested. But, I would still like to discuss this in more detail so that we can understand this better. Cognitive neuroscientist Tali Sharot, author of The Optimism Bias: A Tour of the Irrationally Positive Brain, notes that this bias is widespread and can be seen in cultures all over the world. Sharot also suggests that while this optimism bias can at times lead to negative outcomes like foolishly engaging in risky behaviors or making poor choices about your health, it can also have its benefits. After all, if we didn't believe that we could achieve success, why would we even bother trying? The opposite of optimism bias is pessimism bias (or pessimistic bias), because the principles of the optimistic bias continue to be in effect in situations where individuals regard themselves as worse off than others. It can also lead to poor decision-making, which can sometimes have disastrous results. People might skip their yearly physical, not wear their seatbelt, not add money to their emergency fund, or fail to put on sunscreen because they mistakenly believe that bad things won't happen to them. By believing that we will be successful, people are in fact more likely to be successful. [29] In a research study of four different tests to reduce the optimistic bias, through lists of risk factors, participants perceiving themselves as inferior to others, participants asked to think of high-risk individuals, and giving attributes of why they were at risk, all increased the bias rather than decreased it. The United Kingdom’s Iraq Inquiry, published in 2016, is particularly critical of the Ministry of Defence’s optimistic reporting and disregard of information that conflicted with an overly positive narrative.

Optimism bias is common and transcends gender, ethnicity, nationality and age. (Step two of the approach described in the Supplementary Green Book Guidance (HM Treasury 2003b, p. 3), states that projects should use the appropriate upper bound value for optimism bias as the starting value for calculating the optimism bias … Shereen Lehman, MS, is a healthcare journalist and fact checker. [3] People can control their anxiety and other negative emotions if they believe they are better off than others. [10] Because the optimistic bias can be a strong force in decision-making, it is important to look at how risk perception is determined and how this will result in preventative behaviors. order now. There are two researched ways of reducing the Optimism Bias (Jolls & Sunstein, 2006): Highlight the Availability Heuristic (make past bad events more easily retrievable from one’s memory) and use Loss Aversion (highlight losses that are likely to occur because of these bad events). [9] The optimistic bias is strongest in situations where an individual needs to rely heavily on direct action and responsibility of situations. You say that the financial crisis in 2008 is essentially a result of optimism bias. For example, telling someone the risks of dying from a particular habit such as smoking can actually make them more likely to believe that they will not be negatively affected by the behavior. However, groups of people are considered to be more abstract concepts, which leads to less favorable judgments. Health Psychol. [8][12] Prior experience suggests that events may be less controllable than previously believed. [3], Pessimism bias is an effect in which people exaggerate the likelihood that negative things will happen to them. In health, the optimistic bias tends to prevent individuals from taking on preventative measures for good health. People are less likely to experience the optimism bias when they are comparing themselves to very close loved ones such as friends and family members. While investor beliefs in their ability to predict probable outcomes (overconfidence) increases with information, studies show there is no corresponding increase in prediction accuracy. [3], "Egocentric thinking" refers to how individuals know more of their own personal information and risk that they can use to form judgments and make decisions. Optimism bias is typically measured through two determinants of risk: absolute risk, where individuals are asked to estimate their likelihood of experiencing a negative event compared to their actual chance of experiencing a negative event (comparison against self), and comparative risk, where individuals are asked to estimate the likelihood of experiencing a negative event (their personal risk estimate) compared to others of the same age and sex (a target risk estimate). [21][22] There is a growing body of evidence proving that optimism bias represents one of the biggest single causes of risk for megaproject overspend.[23]. Students also showed larger levels of the optimistic bias than non-students. [12] For example, when drivers are asked to think about a car accident, they are more likely to associate a bad driver, rather than just the average driver. [1], Optimism bias influences decisions and forecasts in policy, planning, and management, e.g., the costs and completion times of planned decisions tend to be underestimated and the benefits overestimated due to optimism bias. [29] Other studies have tried to reduce the bias through reducing distance, but overall it still remains.[14]. [8] While this only applies to events with prior experience, knowing the previously unknown will result in less optimism of it not occurring. [7] Likewise, difficulties can arise in measurement procedures, as it is difficult to determine when someone is being optimistic, realistic, or pessimistic. This is explained in two different ways: For example, many smokers believe that they are taking all necessary precautionary measures so that they won't get lung cancer, such as smoking only once a day, or using filtered cigarettes, and believe that others are not taking the same precautionary measures. Every cloud has a silver lining. In one study, researchers had one group of participants list all factors that influenced their chances of experiencing a variety of events, and then a second group read the list. But by definition, we can't all be above average. Therefore, when making decisions, people have to use other information available to them, such as population data, in order to learn more about their comparison group. [3], It is also possible that someone can escape egocentric thinking. Those who read the list showed less optimistic bias in their own reports. In “Tali Sharot: The Optimism Bias,” examples are provided about how optimism can help to succeed more in life. [1] Optimistic biases are even reported in non-human animals such as rats and birds. Research has found that people show less optimistic bias when experiencing a negative mood, and more optimistic bias when in a positive mood. While we often like to think of ourselves as highly rational and logical, researchers have found that the human brain is sometimes too optimistic for its own good. A new form of optimism bias, namely post-project optimism bias, is defined. 1995;14(2):132–140. While individuals know how to think about themselves as a single person, they still think of others as a generalized group, which leads to biased estimates and inabilities to sufficiently understand their target or comparison group. Optimism Bias. Example 1 – How the optimism bias can affect clinical research. - Adolescents with… The human brain doesn’t always supply accurate information. Clinical research, especially private-sponsored research, exhibits the optimism bias by failing to cite negative results. Clin Psychol Rev. The neural basis of always looking on the bright side. [2], Four factors can cause a person to be optimistically biased: their desired end state, their cognitive mechanisms, the information they have about themselves versus others, and overall mood. ", "Do Moderators of the Optimistic Bias Affect Personal or Target Risk Estimates? Taking stock of unrealistic optimism. [7][8] Problems can occur when trying to measure absolute risk because it is extremely difficult to determine the actual risk statistic for a person. Experts believe that our brains may be wired by evolution to see the glass half-full. 4. optimism bias figure is to be selected from the UK DfT guidance. Infrequent events are more likely to be influenced by the optimism bias. [3] This suggests that overall negative moods, including depression, result in increased personal risk estimates but less optimistic bias overall. The study suggests that bias is stronger for negative events as they are more likely to be involved in risky results and bad behaviours. [31][32] Surveys of smokers have found that their ratings of their risk of heart disease showed a small but significant pessimism bias; however, the literature as a whole is inconclusive. Optimism Bias is a tendency for judgment to be clouded by excitement for the future. Optimism bias (or the optimistic bias) is a cognitive bias that causes someone to believe that they themselves are less likely to experience a negative event. It is also known as unrealistic optimism or comparative optimism. [3] With regards to the optimistic bias, individuals will perceive events more favorably, because that is what they would like the outcome to be. However, unconditional risk questions in cross-sectional studies are used consistently, leading to problems, as they ask about the likelihood of an action occurring, but does not determine if there is an outcome, or compare events that haven't happened to events that have. It contrasts with optimism bias. She has co-authored two books for the popular Dummies Series (as Shereen Jegtvig). Curr Biol. Examples of optimistic bias in a sentence, how to use it. Thank you, {{form.email}}, for signing up. This also suggests that people might lower their risks compared to others to make themselves look better than average: they are less at risk than others and therefore better.[3]. It is part of brain network showing extensive correlation between rostral ACC and amygdala during imagining of future positive events and restricted correlation during imagining of future negative events. [16] This might contribute to overly optimistic attitudes. However, it is likely that many other smokers are doing the same things and taking those same precautions. Research published in 2011 has also shown that people who are depressed or anxious are less likely to experience the optimism bias. So why are we so geared toward optimism? Generally in negative events, the mean risk of an individual appears lower than the risk estimate of others. [30], People with depression are particularly likely to exhibit pessimism bias. Optimism bias examples includes people believing that they are less at risk of being a crime victim, first-time bungee jumpers believing that they are less at risk of an injury than other jumpers, smokers believing that they are less likely to contract lung cancer or disease than other smokers, or traders who think they are less exposed to losses in the markets. [18] For example, people who underestimate their comparative risk of heart disease know less about heart disease, and even after reading an article with more information, are still less concerned about risk of heart disease. This helps us maintain our emotional equilibrium despite sometimes negative events. [17] Another example is that if someone believes that they have a lot of control over becoming infected with HIV, they are more likely to view their risk of contracting the disease to be low. [3] Because information about others is less available, information about the self versus others leads people to make specific conclusions about their own risk, but results in them having a harder time making conclusions about the risks of others. The Idea of Optimistic Bias in Thinking, Fast and Slow, a Book by Daniel Kahneman But we are also highly motivated to be so optimistic. Functional neuroimaging suggests a key role for the rostral Anterior Cingulate Cortex (ACC) in modulating both emotional processing and autobiographical retrieval. [8][10] Research suggests that the bias comes from an overestimate of group risks rather than underestimating one's own risk. 1980;39(5):806-820. doi:10.1037/0022-3514.39.5.806, Prater J, Kirytopoulos K, Ma T. Optimism bias within the project management context: a systematic quantitative literature review. This essay has been submitted by a student. When we are evaluating our risks, we compare our own situation to that of other people, but we are also egocentric. 2013;4:6. doi:10.3389/fpsyg.2013.00006, Weinstein ND, Klein WM. The optimism bias is more likely to occur if the negative event is perceived as unlikely. This leads to differences in judgments and conclusions about self-risks compared to the risks of others, leading to larger gaps in the optimistic bias. Perspect Psychol Sci. [11], The optimistic bias is possibly also influenced by three cognitive mechanisms that guide judgments and decision-making processes: the representativeness heuristic, singular target focus, and interpersonal distance.[3]. For example, studies show that optimistic patients are more likely to eat healthily and engage in exercise. [8] This is then used to demonstrate the bias' effect. Most people have a tendency to overestimate the chances of experiencing a positive (like getting a … The following are some of the factors that make the optimism bias more likely to occur: Below are some of the factors that decrease the optimism bias: While researchers have attempted to help people reduce the optimism bias, particularly to promote healthy behaviors and reduce risky behaviors, they have found that reducing or eliminating the bias is actually incredibly difficult. These explanations include self-enhancement, self-presentation, and perceived control. Read more at: http://psychyogi.org/psychology-concepts/the-optimism-bias/ Also regarding egocentric thinking, it is possible that individuals underestimate the amount of control the average person has. The relevance of optimism bias therefore goes further than the issues of driving education and the framing of safety advertising campaigns, however. Ethic Theory Moral Prac. Therefore, researchers need to be aware of the optimistic bias and the ways it can prevent people from taking precautionary measures in life choices. This optimism, she also explained in a 2012 TED Talk, can act as a self-fulfilling prophecy. The difference is that we are in an improbable way worried about our society's future. Kendra Cherry, MS, is an author, educational consultant, and speaker focused on helping students learn about psychology. [8], An example: participants assigned a higher probability to picking a card that had a smiling face on its reverse side than one which had a frowning face.
