Optimism Bias (偏见)

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. If you were asked to estimate how likely you are to experience illness, job loss, or an accident, you are likely to underestimate the probability that such events will ever impact your life. 1.

This bias leads us to believe that we are less likely to suffer from misfortune and more likely to attain success than reality would suggest. We believe that we will live longer, and that we will be more successful in life than the average. 2.

The optimism bias is essentially a mistaken belief that our chances of experiencing negative events are lower and our chances of experiencing positive events are higher than those of our peers. And this overly positive assumption doesn’t mean that we have an overly sunny outlook on our own lives. 3. People might skip their yearly physical, not wear their seatbelt, or fail to put on sunscreen because they mistakenly believe that they are less likely to get sick, get in an accident, or get skin cancer.

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. 4. If we expect good things to happen, we are more likely to be happy. This optimism can act as a self-fulfilling prophecy. By believing that we will be successful, people are in fact more likely to be successful.

5. After all, if we didn’t believe that we could achieve success, why would we even bother trying? Optimists are also more likely to take measures to protect their health such as exercising, taking vitamins, and following a nutritious diet.

A.Optimism also motivates us to pursue our goals.

B.But we are also highly motivated to be so optimistic.

C.But definitely not everyone is blessed with such luck.

D.This is because your brain has a built-in optimism bias.

E.It can also lead to poor decision-making, which can sometimes have disastrous results.

F.This optimism enhances well-being by creating a sense of anticipation about the future.

G.Various causes may lead to the optimistic bias, including cognitive and motivational factors.
