3 . Scientists are embracing artificial intelligence (AI) — from developing “self-driving” laboratories to replacing human participants in social-science experiments with robots. Many disadvantages of AI systems have been discussed. In an article published in Nature this week, social scientists say that AI systems carry a further risk: that researchers perceive such tools as possessed of superhuman abilities when it comes to objectivity, productivity and understanding complex concepts.

Scientists planning to use AI “must evaluate these risks now”, write co-authors Lisa Messeri and Molly Crockett. The article is a warning about what could be lost if scientists embrace AI systems without thoroughly considering such risks.

Messeri and Crockett examined around 100 papers and books, published mainly over the past five years. From these,they put together a picture of the ways in which scientists see AI systems as enhancing human capabilities.

In one “vision”, which they call AI as Oracle, researchers see AI tools as able to tirelessly read and digest scientific papers. In another vision, called AI as Arbiter, systems are perceived as evaluating scientific findings more objectively than do people. In a third vision, AI as Quant, AI tools seem to perform better than the human mind in analyzing data sets.

Messeri and Crockett also predict risks that arise from these visions. One is the illusion (幻觉) of explanatory depth, in which people relying on another person-or，in this case，an algorithm (算法) — for knowledge are likely to mistake that knowledge for their own. Another risk is that research becomes skewed (偏颇的) towards studying the kinds of things that AI systems can test.

If you’re a scientist planning to use AI, you can reduce these dangers through a number of strategies.All members of the scientific community must view AI use not as unavoidable for any particular task, but rather as a choice with risks and benefits that must be carefully weighed.

4 . Are you longing for a travel experience full of iconic attractions, which is not only immersive but also intimate? Offering attentive guides, unique experiences, and the perfect combination of exploration and friendship, small group travel is redefining the holiday experience.     1    .

●Explore uncharted but safe territories. Take a journey to breathtaking destinations that might otherwise be frightening to explore independently.     2    , ensuring you don't miss out on the essence (精髓) of each destination. It can also offer exciting exclusive experiences. With smaller coaches and personalized schedule, you'll deep into local cultures and taste authentic flavors at every turn.

●Be guided by the local guides.     3    . Small group tours are led by knowledgeable guides who not only speak the language but also offer insights into the culture, history, and hidden treasures of each region. These guides ensure your journey is enriched with authenticity and discovery.

●     4    . Whether you're travelling alone or with friends, small group travel fosters a sense of community. With groups typically including fewer than 30 people, you'll have the opportunity to form meaningful connections and create lasting memories with fellow adventurers. From shared experiences to newfound friendships, it cultivates a sense of friendship that enhances the overall holiday experience.

●Start your adventure with peace of mind. Small group tour operators take care of everything. With convenience at the forefront, you can explore outside your comfort zone, knowing that every detail has been thoughtfully arranged.     5    , offering assistance in case of emergencies and give you peace of mind through licensed and bonded services.
