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.
The first patient who died on my watch was an older man with a faulty heart — the main pump had failed and his heart was beating irregularly and far too fast. We tried to slow it down with treatment, but it suddenly stopped beating completely. Later, whenever I would have a case like that one, I found myself second-guessing my clinical management. However, it turns out that thinking twice may actually cause more harm than good.
In a working paper, Emory University researchers found that when doctors delivering a baby have an adverse outcome, they are more likely to switch to a different delivery method with the next patient, often unnecessarily and sometimes with worse results.
Because doctors make so many decisions that have serious consequences, the fallout from second-guessing looms especially large for us. A 2006 study found that if a patient had a bleed after being prescribed warfarin, the physician was about 20% less likely to prescribe subsequent patients the blood thinner that prevents strokes. However, if a patient had a stroke and was not on warfarin, physicians were still no more likely to prescribe warfarin to their other patients.
These findings highlight interesting behavioral patterns in doctors. In the blood-thinner study, doctors were more affected by the act of doing harm (prescribing a blood thinner that ended up hurting a patient) and less affected by letting harm happen (not prescribing a blood thinner and the patient having a stroke). Yet a stroke is often more permanent and damaging than a bleed.
But this phenomenon is not unique to medicine. “Overreaction to Fearsome Risks” holds true for broader society.
For instance, sensational headlines about shark attacks on humans in Florida in 2001 caused a panic and led the state to prohibit shark feeding expeditions. Yet shark attacks had actually fallen that year and, according to the study, such a change was probably unnecessary given the extremely small risk of such an attack happening.
Humans are susceptible to emotional and often irrational thinking when processing information, adverse events and mistakes. As much as we don’t want to cause an unfortunate event to recur — in a medical setting or in the wider world — we need to be aware that a worst case scenario doesn’t necessarily mean we did anything wrong. When we overthink, we fail to rely on thinking based on what we know or have experienced. Instead, we may inadvertently overanalyze and come to the wrong conclusion.
I have treated dozens of patients who presented with the same illnesses as my first patient, who died more than a year ago. Instead of second guessing myself, I trusted my clinical instinct and stayed the course. Every one of those patients survived. You should trust your instinct in your life, too.

Although it has been revealed in recent years that plants are capable of seeing, hearing and smelling, they are still usually thought of as silent. But now, for the first time, they have been recorded making ultrasonic cries when stressed, which researchers say could open up a new field of precision agriculture where farmers listen for water-starved crops.
Itzhak Khait and his colleagues at Tel Aviv University in Israel found that tomato and tobacco plants made cries at frequencies humans cannot hear when stressed by a lack of water or when their stem is cut.
Microphones placed 10 centimetres from the plants picked up sounds in the ultrasonic range of 20 to 100 kilohertz, which the team says insects and some mammals would be capable of hearing and responding to from as far as 5 metres away. A moth may decide against laying eggs on a plant that sounds water-stressed, the researchers suggest. Plants could even hear that other plants are short of water and react accordingly, they speculate.
On average, drought-stressed tomato plants made 35 sounds an hour, while tobacco plants made 11. When plant stems were cut, tomato plants made an average of 25 sounds in the following hour, and tobacco plants 15. Unstressed plants produced fewer than one sound per hour, on average.
It is even possible to distinguish between the sounds to know what the stress is. The researchers trained a machine-learning model to discriminate between the plants’ sounds and the wind, rain and other noises of the greenhouse, correctly identifying in most cases whether the stress was caused by dryness or a cut, based on the sound’s intensity and frequency. Water-hungry tobacco appears to make louder sounds than cut tobacco, for example.
Enabling farmers to listen for water-stressed plants could “open a new direction in the field of precision agriculture”, the researchers suggest. They add that such an ability will be increasingly important as climate change exposes more areas to drought.
“The suggestion that the sounds that drought-stressed plants make could be used in precision agriculture seems feasible if it is not too costly to set up the recording in a field situation,” says Anne Visscher at the Royal Botanic Gardens, Kew, in the UK.
She warns that the results can’t yet be broadened out to other stresses, such as salt or temperature, because these may not lead to sounds. In addition, there have been no experiments to show whether moths or any other animal can hear and respond to the sounds the plants make, so that idea remains speculative（推测的）for now, she says.
