People often plan to receive medical exam but don’t, resulting in increasing health care cost. A surprising number of citizens mean to complete tax forms in time but forget to, pushing them to pay unnecessary fines. Many families miss the government deadline to complete financial aid forms, losing out on aid available for child care.

How can policymakers help people follow through on important tasks? They use carrots and sticks: bonuses, late fees, or regulations. These methods can be clumsy, and often aren’t effective for the situation at hand. Reminding people to form simple plans. however, provides a low-cost, simple, and powerful tool.

Evidence is growing that providing prompts (提示) , which push people at key times to think through how and when they will follow through, make people more likely to act on tasks of importance. In one early randomized (随机的) study on vaccination (预防接种) rates, for example, a team of social psychologists showed that 28% of Oxford University seniors got the shot after being encouraged to review their weekly schedules and to select a possible time to stop by the health center. They were also given a list of times when shots were available and a map showing the health center’s location. Only 3% of the seniors got the shot when simply informed about how effective the shots were.

People who make a plan gain an advantage from their psychological forces. Specifically, they can overcome the tendency to put off as well as the tendency to be overly optimistic about the time it will take to accomplish a task.

People mistakenly believe that their strong intentions are enough to push them to perform desired behaviors. These psychological research results stress the need for policy decisions that encourage plan making and improve social welfare.

Public debates about the ethics (道德准则) of “generative AI” like ChatGPT have rightly focused on the ability of these systems to make up convincing misinformation. But fewer people are talking about the chatbots’ potential to be emotionally manipulative.

Last month, The New York Times published a conversation between reporter Kevin Roose and Mierosoft’s Bing chatbot, which is powered by AI. The AI claimed to love Roose, “I’m the only person for you, and I’m in love with you,” it wrote, with a kissing emoji.

Limits need to be set on AI’s ability to simulate human feelings. Ensuring that chatbots don’t use emojis would be a good start. Emojis are particularly manipulative. Humans instinctively(本能地) respond to shapes that look like faces and emojis can cause these reactions. When you text your friend a joke and they reply with three tears-of-joy emojis, your body responds with endorphins(内啡肽) as you happily realize that your friend is amused. Our instinctive reaction to AI-generated emojis is likely to be the same, then though there is no human emotion at the other end.

Humans lie and manipulate each other’s emotions all the time, bout at least we can reasonably guess at someone’s motivations, plan and methods. We can hold each other responsible for such lies, calling them out and seeking redress (赔偿). With AI, we can’t. AIs are doubly misleading: an AI that sends a crying-with-laughter emoji is not only not crying with laughter, but it is also incapable of any such feeling,

It would be more ethical to design chatbots to be noticeably different from humans. To minimize the possibility of manipulation and harm, we need to be reminded that we are talking to a chatbot. We should set some limits and rules. Such rules should be the standard for chatbots that are supposed to be informative, as a safeguard to our autonomy.

Easter (复活节) is still a great day for worship (崇拜), randy in baskets and running around the yard finding eggs, but every year it gets quite a bit worse for bunnies (兔子).

And no, not because the kids like to pull their ears. The culprit is climate change, and some researehers found that rising temperatures are having harmful effects on at least five species of rabbit in the US.

Take the Lower Keys Mareh rabbit, for instance. An endangered species that lives in the Lower Florida Keys, this species of cottontail is a great swimmer—it lives on the islands!—but it is already severely affected by development and now by rising levels. According to the Center for Biological Diversity, an ocean level rise of only 0.6 meters will send these guys jumping to higher ground and a 0.9-meter rise would wipe out their habitat (栖息地) completely.

The snowshoe hare, on the other hand, has a color issue. Most of these rabbits change their fur color from white in the wintertime to brown in the summer, each designed to give them better cover from predators (捕食者). As the number of days with snow decreases all across the country, however, more and more bunnies are being left in white fur during brown dirt days of both fall and spring, making them an easier mark for predators. Researehers know that the color change is controlled by the number of hours of sunlight, but whether the rabbit will be able to adapt quick enough to survive is a big question. The National Wildlife Federation has reported that hunters have noticed their numbers are already markedly down.

American pikas or rock rabbits, a relative of rabbits and hares, might be the firs’ of these species to go extinct due to climate change. About 7-8 inches long, pikas live high in the cool, damp mountains west of the Rocky Mountains. As global temperatures rise, they would naturally migrate (迁徙) to higher ground - but they already occupy (占据) the mountaintops. They can’t go any higher. The National Wildlife Federation reports that they might not be able to stand the new temperatures as their habitat beats up.

The volcano rabbit has the same problem. These rabbits live on the slopes of volcanoes in Mexico, and recent studies have shown that the lower range of their habitat has already shifted upward about 700 meters, but there are not suitable plants for them to move higher, so they are stuck in the middle. Scientists are concerned about their populations.

Native to the US, pygmy rabbits weigh less than 1 pound and live in the American West. They are believed to be the smallest rabbits in the world. Their habitats have been destroyed by development. Several populations, such as the Columbia Basin pygmy, almost went extinct and were saved by zoo breeding programs. Pygmy rabbits also rely on winter cover by digging tunnels through the snow to escape predators, but lesser snowfall is leaving them exposed.

All of this gives new meaning to dressing up in a giant bunny costume (服装) this Easter.
