风险还是回报:当决策不确定时,人们最想先知道什么?
加州大学圣地亚哥分校的一项新研究揭示了人们在面对不确定决策时的信息偏好顺序:大多数人首先希望了解潜在风险,而非潜在回报。研究表明,在不确定性情境下,风险信息比收益信息更受重视,这一发现对理解人类决策行为具有重要意义。

A state-designed worm from 2005 called Fast16 sat undetected on VirusTotal for nearly a decade. It intercepted executable files at the kernel level and silently altered floating-point calculations in high-precision engineering software like LS-DYNA, which was used in Iran's nuclear weapons research. Unlike Stuxnet, Fast16 received little public attention for over twenty years.
Paul Graham reports that Y Combinator startups now have over 75% of their code written by AI, a threshold crossed at least one to two years ago. This parallels a similar transformation at Google, where AI-written code went from 0% to 75% in about two years.
Scientists are increasingly concerned about the potential collapse of the Atlantic Meridional Overturning Circulation (AMOC), a critical ocean current system. Such a collapse could have severe consequences for North America and Europe.
A compromised version of the LiteLLM Python package (version 1.82.8) was briefly available on PyPI, capable of exfiltrating sensitive credentials like SSH keys and cloud secrets. The malicious package affected any project that depended on LiteLLM, though it was only available for about an hour before discovery.
A supply chain attack has compromised the popular npm axios HTTP client library with 300 million weekly downloads. Malicious versions install a remote access trojan, though some users may have avoided infection through version pinning or older installations. Security experts warn this is a live compromise affecting one of npm's most depended-on packages.
