ur head at a colleague’s agony over a decision when the answer is crystal-clear,there’s a scientific reason behind it. Our own decision-making abilities can become depleted over the course of the day causing indecision or poor choices, but choosing on behalf of someone else is an enjoyable task that doesn’t suffer the same pitfalls. The problem is “decision fatigue,” a psychological phenomenon that on the quality of your choices after a long day of decision making, says Evan Polman, a leading psychologist.

Physicians who have been on the job for several hours, for example, are more likely to prescribe antibiotics to patients when it’s unwise to do so. “Presumably it’s because it’s simple and easy to write a prescription and consider a patient case closed rather than investigate further,” Polman says.

But decision fatigue goes away when you are making the decision for someone else. When people imagine themselves as advisers and imagine their own choices as belonging to someone else, they feel less tired and rely less on decision shortcuts to make those choices. “By taking upon the role of adviser rather than decision maker, one does not suffer the consequences of decision fatigue,” he says. “It’s as if there’s something fun and liberating about making someone else’s choice.”

Getting input from others not only offers a fresh perspective and thought process, it often also includes riskier choices. While this sounds undesirable, it can be quite good, says Polman. “When people experience decision fatigue—when they are tired of making choices—they have a tendency to choose to go with the status quo (现状), he says. But the status quo can be problematic, since a change in the course of action can sometimes be important and lead to a positive outcome.”

In order to achieve a successful outcome or reward, some level of risk is almost always essential. “People who are susceptible to decision fatigue will likely choose to do nothing over something,” he says. “That’s not to say that risk is always good, but it is related to taking action, whereas decision fatigue assuredly leads to inaction and the possible chagrin(懊恼)of a decision maker who might otherwise prefer a new course but is unfortunately hindered.”

Just because you can make good choices for others doesn’t mean you’ll do the same for yourself, Polman cautions. “Research has found that women negotiate higher salaries for others than they do for themselves,” he says, adding that people slip in and out of decision roles.

The top of the world is a wonderland. In winter, the temperature often fails to -30~F and the sun never rises. The ocean is surrounded by frozen ground. There are few people or trees, but to polar bears, the Arctic(北极) is home.

Polar bears have thick fur, big paws and other features that make them well prepared for life in their tough environment. In fact, they need the Arctic sea ice for survival. But climate change is causing larger and larger areas of summer sea ice to melt(融化). Experts say that if warming pat-terns continue, the Arctic could be free of summer sea ice by 2050. That may cause two-thirds of the word&39; s 20,000 polar bears to be gone by then too.

Polar bears can&39; t survive for long on land. Seals are their main source of food. The only place where polar bears can hunt seals is on the ice. Although these bears are strong swimmers, they are no match for lighming swift seals in the water. A polar bear has brilliantly clever strategies to overcome this disadvantage. In winter the bear waits motionless beside a seal&39; s breathing hole, which is a narrow tunnel through the ice. Often many hours pass before the seal comes up for air and the bear kills it with a powerful blow of its paw. In summer, the polar bears that live on land eat very little and wait for the sea ice to return.

With the sea ice forming later in the year and melting earlier, polar bears do not have enough opportunity to hunt and eat. Less sea ice makes it harder for the bears to catch the seals. The bears must swim longer distances between ice packs(大片浮冰), and they can&39; t always make it.. The ice is also getting thinner. These conditions can cause polar-bear cubs to become separated :from their mothers, who provide them with food.

Steven Amstrup is the chief scientist of Polar Bear International. The group aims to save the bears and their home. "The more people who see polar bears and understand their difficult situations, the better the chance we&39; 11 alter our warming path in time to save them," he says.
