Short answer: Yes, the evidence strongly suggests they are — though the science is still evolving on mechanisms and specifics. The observational evidence is substantial and consistent The largest review to date — an umbrella review of 45 meta-analyses covering nearly 10 million people, published in The BMJ in 2024 — found 45 analyses published in the last three years, involving about 10 millio

Short answer: It's complicated — "no" and "yes," depending on what you mean by "reverse" There's no single yes/no answer, because scientists distinguish between stopping further warming, reversing it entirely, and avoiding irreversible damage — and the news on each is different. The optimistic case: It's not "game over" Many climate scientists push back hard against pure doomism. The idea that

The question of whether the United Nations remains relevant is one of the most pressing debates in global politics. As the UN marks its 80th anniversary and navigates a critical transition—with member states currently selecting a new Secretary-General to succeed António Guterres—the organization is facing a crisis of legitimacy, effectiveness, and funding. To understand if the UN is still releva

Social media is neither clearly more harmful nor more helpful overall—it is a powerful tool whose net effects depend heavily on how it is used, by whom, for how long, the specific platforms/content, and individual vulnerabilities. Scientific evidence shows small average effects (often explaining less than 1–4% of variance in well-being), with both documented risks (especially for adolescents) and

Yes — the evidence strongly suggests ultra-processed foods (UPFs) are a public health hazard A growing and increasingly robust body of scientific evidence supports classifying UPFs as a significant public health concern. What counts as a UPF UPFs are industrially manufactured products that typically contain additives and ingredients not found in home cooking. Examples include packaged snacks,

Yes, by several key modern metrics—especially in the United States—political polarization is worse than it has been in recent decades (roughly post-World War II through the 1980s/1990s), though it is not unprecedented in all of U.S. history and does not match the intensity of crises like the Civil War era in terms of violence or existential stakes. Polarization has multiple dimensions (ideological

There is no single objective answer—it depends on values (e.g., fairness, equity vs. efficiency, property rights), definitions of “wealthy” and “higher,” measurement of tax burdens and income/wealth, and empirical trade-offs involving revenue, inequality, growth, and behavior. The U.S. (the most common reference point for such debates) already has a progressive federal income tax, but debates cent

NATO (North Atlantic Treaty Organization) is best evaluated as a net force for good in the Euro-Atlantic area by the standards of collective defense, deterrence of major war, and promotion of democratic stability among its members—but its record is mixed globally, with notable failures in out-of-area interventions and contributions to geopolitical tensions.[[1]](https://en.majalla.com/node/320506/

The question of whether the wealthy should pay a higher tax rate is one of the most enduring debates in economics, politics, and social philosophy. There is no global consensus, as the issue involves fundamental trade-offs between economic efficiency, social equity, and different views on the role of government. Here is an overview of the primary arguments on both sides of the debate. --- Arg

Social media is neither clearly more harmful nor more helpful overall—its effects are complex, typically small on average, highly variable by individual, usage patterns, platform, content, age, and context, and often reciprocal (poor well-being can drive more use, and vice versa). Sweeping claims in either direction oversimplify the evidence from meta-analyses, longitudinal studies, experiments, a

Short answer: It's genuinely contested, but the weight of recent economic evidence leans toward "yes, with caveats." This is a long-debated question in economics, and reasonable researchers disagree. Here's a balanced look at the evidence on both sides. The case for unions being good Higher wages for members. The "union wage premium" is well documented: a worker covered by a union contract ea

The question of whether wealthy individuals should pay a higher tax rate is one of the most central and long-standing debates in economics, politics, and social philosophy. There is no global consensus, as the debate involves a fundamental trade-off between economic equity (how fairly resources are distributed) and economic efficiency (how effectively a society generates wealth). Here is an over

Social media is neither purely more harmful nor purely more helpful—it is a double-edged tool whose net impact depends heavily on how it is used, by whom, the specific content and platforms, age, individual vulnerabilities, and context. Average effects on well-being are often small, but risks can be substantial (especially for adolescents), while benefits are real for connection, information, and

This is a genuinely debated topic in economics with legitimate arguments on multiple sides. Let me pull in some current research and data to give you a well-rounded picture.This is a genuinely contested question in economics, with research pointing to real benefits for union members alongside legitimate tradeoffs for firms and the broader economy. Here's a balanced picture: The Case For Unions

Yes — according to the weight of current scientific evidence, ultra-processed foods (UPFs) are increasingly viewed as a genuine public health hazard, though some scientific debate remains about precision and causality. The case that UPFs are a public health hazard A major scientific consensus has just hardened. In November 2025, a Lancet Series on ultra-processed foods and human health conclude

Whether labor unions are "good" for workers and the economy is one of the most long-standing debates in economic and social policy. To understand this debate, economists often refer to the framework established by labor economists Richard Freeman and James Medoff in their seminal book What Do Unions Do?. They argued that unions have "two faces": a "monopoly face" (where unions act as cartels to

Based on current analyses, today's U.S. political climate presents several interconnected threats, spanning institutional, electoral, and social dimensions: 1. Erosion of Checks and Balances / Executive Power Analysts point to a significant expansion of executive authority. Congress's inability to effectively fulfill its responsibilities has been accompanied by increasingly extreme assertions of

The question of whether the wealthy should pay higher tax rates is one of the most enduring debates in economics, politics, and social philosophy. Because it touches on fundamental questions about fairness, government's role in society, and economic incentives, there is no universal consensus. The primary arguments from both sides of the issue highlight the trade-offs of different tax policies.

Yes, in the United States—where the phenomenon is most intensively studied—political polarization is worse by many standard measures than it has been in recent decades (roughly since the mid-20th century), though it does not match the extreme divisions of the Civil War era, and comparisons to other historical peaks like the 1960s are more nuanced.[[1]](https://today.usc.edu/political-polarization-

Yes, a substantial and rapidly growing body of scientific evidence indicates that ultra-processed foods (UPFs) pose a genuine public health hazard, though there's important nuance about the strength of evidence for different health outcomes and ongoing debate about mechanisms. The Case That UPFs Are a Public Health Hazard Scale of the problem: The U.S. is among the biggest consumers of UPF in t

Short answer: No, but "reversing" it fully in our lifetime isn't realistic — the better goal is stopping it from getting much worse. Climate change isn't an all-or-nothing switch. It's more useful to separate the question into a few parts: 1. Can we reverse warming that's already happened? Not quickly, and some effects not at all on human timescales. True climate reversal would require activel

Whether political polarization is "worse" than in the past depends on which era of history you use as a benchmark. If you compare today to the mid-to-late 20th century, the answer is a resounding yes. However, if you look further back into the arc of American history, the country has survived several eras of equal or even greater division. --- 1. Yes, It is Worse Than in Recent Memory For an

The question of whether the United Nations (UN) is still relevant is one of the most pressing debates in modern international relations. While many critics argue that the UN is increasingly paralyzed and outdated, supporters maintain that it remains an indispensable, irreplaceable foundation of global cooperation. The UN's current relevance is best understood by looking at where the organization

NATO (North Atlantic Treaty Organization) is a collective defense alliance whose net impact is widely debated and depends heavily on one's values, geography, and view of international order. It is not inherently "good" or "evil"; it is a tool of statecraft that has delivered clear security benefits for its members while producing mixed or negative outcomes in some interventions and contributing to

The question of whether China is a threat to United States interests is one of the defining debates of 2020s global politics. Across the U.S. political spectrum, a strong consensus has emerged that China is the most significant, long-term strategic competitor to the United States. However, foreign policy experts, government officials, and economists debate whether this competition is best understo

Whether the wealthy should pay higher taxes is one of the most enduring and highly debated topics in economics, politics, and social philosophy. The discussion involves not only income taxes but also capital gains taxes, estate taxes, and potential "wealth taxes" on accumulated assets. There are compelling and deeply held arguments on both sides of this debate. --- Arguments in Favor of Raisi

Social media is neither clearly more harmful nor more helpful overall—its effects are nuanced, typically small, highly dependent on how, how much, by whom, and in what context it is used, and often bidirectional or confounded by other factors.[[1]](https://www.cell.com/trends/cognitive-sciences/fulltext/S1364-6613%2820%2930251-5)[[2]](https://pmc.ncbi.nlm.nih.gov/articles/PMC11629030/) Large-scal

Are Labor Unions Good for Workers and the Economy? The evidence is mixed and depends heavily on who you ask and what outcome you're measuring. Here's a balanced breakdown: The Case For Unions Higher wages, especially for workers who need it most. The research is fairly consistent that unionized workers earn more than comparable nonunion workers. On average, a worker covered by a union contrac

Whether political polarization is "worse" than in the past depends heavily on how you measure it and which era of the past you are comparing it to. If you compare today to the last 50 to 60 years, yes, political polarization is at its worst in living memory. However, if you look at the broader arc of American history, the nation has survived periods of equal or even more destructive division. -
