What is the optimism bias and how does it manifest?
What is the optimism bias? Thanks for asking. Today we're going to talk about a cognitive bias that causes people to believe, often mistakenly, that they are less likely to experience negative events and more likely to experience positive events than others. Estimates suggest that 80% of us display what's known as the optimism bias.
For example, we might think that we're less likely to get sick, lose our job, or have a car accident than the average person. We might also think that we're more likely to live longer, be successful, or win the lottery.
Why do we have such a bias, and how does it affect our decisions and actions?
Several factors can help explain optimism bias. First of all, according to Tali Sharot, a professor of cognitive neuroscience at UCL, the positive events that happen to us or that we hear about are more likely to cause us to update our belief systems than the negative ones. She says that the optimism bias is resistant in the face of reality.
Despite that, there are actually benefits that come with the optimism bias. It can help both our mental and physical health. Expecting positive outcomes reduces stress and anxiety levels, boosts our immune system, and motivates us to pursue our goals. It can even act as a self-fulfilling prophecy in some scenarios, meaning we succeed because we believe we can.
Optimism helps us cope with uncertainty and adversity. It gives us a sense of control over our lives and makes us resilient in the face of challenges. drawbacks of optimism bias? The flip side is it can lead us to underestimate risks and overestimate opportunities. That might make us engage in risky or harmful behaviour like smoking, drinking or gambling.
We may also neglect precautionary measures such as wearing seatbelts, getting vaccinated or saving money. The optimism bias can make us overconfident and complacent. That can impair our judgment and performance, and prevent us from learning from our mistakes or seeking feedback.
For example, in the workplace, it can make us blind to the reality of the world and the problems that need to be solved. That can hinder our ability to empathize with others, acknowledge different perspectives, or take collective action. One of the areas where optimism bias can have serious consequences is the global climate crisis.
Many people tend to believe that climate change will not affect them personally, or that it will be solved by technology or policy before it gets worse. That's despite repeated warnings from climate experts and organisations like the IPCC, whose reports have shown just how pressing the crisis is.
