The article argues that the Federal Reserve's recent rate hike decision, while justifiable on inflation grounds, highlights a critical lack of an underlying, transparent policy framework. The core problem is that the Fed's decisions appear discretionary, leading to market uncertainty because the committee's judgment, rather than clear data, dictates policy shifts. The author proposes that the Fed adopt a formal monetary policy rule—an algebraic formula linking the target rate to indicators like inflation and unemployment—to replace subjective guidance. Implementing such a rule would provide market predictability, enhance transparency, and shield the Fed from political attacks by making deviations from the standard easily quantifiable.
Is it time to measure cognitive stunting?
English Summary
The Brookings report argues that overreliance on generative AI poses a risk of 'cognitive stunting' in children, a condition where the lack of effortful thinking opportunities prevents the development of essential cognitive skills. This risk is evidenced by the fact that AI allows students to shortcut the necessary struggle and practice required for deep learning, leading to diminished critical thinking and neural engagement. Policy implications suggest that policymakers must treat this issue like physical stunting, necessitating the development of systematic, age-normed measures to track cognitive development in relation to AI use. Ultimately, the report calls for congressional action to establish a clear measurement framework and guide AI developers to support, rather than replace, the learning process.
中文摘要
布魯金斯智庫的報告指出，過度依賴生成式AI可能導致兒童出現「認知遲滯」（cognitive stunting）的風險。此症狀的特點是缺乏需要費力思考的機會，從而阻礙了基本認知技能的發展。報告提出，此風險的證據在於AI使學生得以繞過深度學習所需的必要掙扎與實踐，進而導致批判性思維和神經參與度（neural engagement）的下降。政策層面的啟示是，政策制定者必須將此問題視為類似於體能遲滯，有必要建立系統性、符合年齡標準的衡量指標，以追蹤與AI使用相關的認知發展狀況。最終，該報告呼籲國會採取行動，建立明確的衡量框架，並指導AI開發者應支持而非取代學習過程。

The ongoing Ebola outbreak in the DRC serves as a critical warning that the global health security system is fundamentally unprepared for future biological threats. The difficulty in containing this outbreak is compounded by the rising risk of emerging pathogens and the growing potential for AI misuse in bioweapon development. Policy must therefore shift from reactive, crisis-driven funding to sustained, proactive investment in resilient public health infrastructure, particularly in conflict zones. Addressing this requires strengthening global surveillance, ensuring consistent international cooperation, and mitigating the intersection of conflict, climate change, and disease spread.

3.A Design Lab Pilot to Inform Strategies for Expanding Access to Medications for Opioid Use Disorder in Community Mental Health Centers (RAND)
Despite MOUD being the standard of care for opioid use disorder, access remains severely limited in Community Mental Health Centers (CMHCs), which serve the primary population with co-occurring disorders. A Design Lab pilot identified payment limitations and regulatory complexity as the chief barriers to implementation. The most feasible and high-impact strategy identified was establishing a structured learning exchange between CMHC leaders and insurers to improve reimbursement understanding. Policymakers and payers are therefore advised to pilot this learning exchange model to initiate broader payment reform and expand evidence-based care for this vulnerable population.

The article argues that modern conflicts are increasingly defined by attrition, driven by three strategic gaps: the difference between nominal military power and usable capacity; the difficulty of achieving breakthroughs in a technologically advanced battlefield; and the detachment of military means from clear political objectives. Evidence from Ukraine and the Middle East demonstrates that sustained logistics, rapid technological adaptation, and proxy networks are now more decisive than sheer military size. For policymakers, this implies a strategic shift away from seeking short, decisive victories toward preparing for prolonged, high-cost engagements, requiring a focus on sustainable supply chains and defining concrete, attainable political end-states.

Congress has significantly expanded presidential tariff authority by passing the Lindsey O. Graham Sanctioning Russia and Iran Act of 2026, allowing the executive to impose up to 100% tariffs on key buyers of Russian energy and sanctions enablers. The article argues that this legislation represents a dangerous abdication of Congress's Article I authority, as it grants the executive vast, discretionary power without specifying criteria for enforcement. Historically, the executive could claim tariffs were its own doing; however, by writing and passing this new authority, Congress now owns the resulting trade policy and its economic consequences. This shift implies that future tariffs will be viewed by the public as a direct legislative action, potentially undermining the administration's credibility and creating political vulnerability.
