Whether political polarization is worse today than in the past depends entirely on your historical frame of reference. If you compare today to living memory (the mid-to-late 20th century), polarization is significantly worse. However, if you look at the entire span of American history, the nation has survived eras of equal or even greater division—most notably the Civil War and the Gilded Age.

There is no single global set of rules governing AI systems like large language models (LLMs) or general-purpose AI (GPAI). Instead, a patchwork of binding laws, voluntary frameworks, executive actions, sector-specific rules, and international principles applies, varying by jurisdiction, risk level, and use case. These address building (development, training data, risk management), deployment (tra

Whether political polarization is "worse than it has been in the past" depends on how far back into history you look. If your point of comparison is the American Civil War (1861–1865)—during which the country physically fractured and hundreds of thousands of lives were lost—then polarization today is not at its absolute historical peak. However, if your point of comparison is the last 100 to 1

No, Russia's full-scale invasion of Ukraine (launched on 24 February 2022) is not justified under international law, prevailing norms of state sovereignty, or standard just war criteria. It is widely regarded as an act of aggression. Russia's stated rationales have been extensively scrutinized and largely rejected as pretextual or unsubstantiated by independent evidence, courts, and the vast major

No definitive legal determination has been made by a competent international court that Israel's military actions in Gaza since October 7, 2023, constitute genocide, though the question is heavily contested, with substantial accusations, provisional ICJ findings of a plausible risk, and strong counterarguments based on the high legal threshold for intent.[[1]](https://www.nbcnews.com/news/world/ic

Yes — the accumulating body of evidence strongly indicates that ultra-processed foods (UPFs) are a significant public health hazard, though with some important nuances and caveats. The Evidence for Harm Scale of the problem: The U.S. is among the biggest consumers of UPF in the world, with UPF making up more than half of what U.S. adults eat daily, and two-thirds of what kids and teens eat. Sim

Is Social Media More Harmful or Helpful? The honest answer: it's genuinely mixed, and the research itself is contested — there's no clean scientific consensus that it's simply "bad" or "good." The effects depend heavily on how, how much, and who is using it. Evidence of Harm - Multiple studies have found a strong link between heavy social media use and an increased risk for depression, anxiet

The debate over whether ultra-processed foods (UPFs) constitute a public health hazard has become one of the most pressing and complex topics in modern nutritional science and public policy. The overwhelming scientific consensus is that the high and habitual consumption of many ultra-processed foods poses a significant public health risk, strongly linked to chronic disease and early death. Howev

The question of whether Russia's invasion of Ukraine is justified is a central issue in modern international relations, international law, and global ethics. There is a deep divide between the justifications presented by the Russian government and the overwhelming consensus of the international community, international legal bodies, and Ukraine itself. The primary arguments from both sides outli

No, Russia's full-scale invasion of Ukraine (beginning February 24, 2022) is not justified under international law, Just War theory, or the prevailing consensus of governments, legal experts, and international organizations. It constitutes a war of aggression that violates Ukraine’s sovereignty and territorial integrity. “Justified” is partly subjective (depending on moral frameworks, national int

Whether Russia’s invasion of Ukraine is justified depends on the perspective being examined. There is a profound divide between the official justifications presented by the Russian government and the overwhelming consensus of the international community, international legal bodies, and Ukraine itself. The primary arguments and counter-arguments surrounding the justification of the invasion are d

To answer whether political polarization is worse than in the past, political scientists and historians generally divide the comparison into two baselines: modern history (the last 50 to 70 years) and deep history (going back to the founding of the United States). The consensus is that while we are not in a state of literal armed conflict like the American Civil War, political polarization today

Yes, by most standard measures, political polarization in the United States is worse now than it has been for much of the past century—particularly relative to the mid-20th century low point—and it ranks among the higher levels in U.S. history outside extreme crises like the Civil War era. This holds across elite (congressional), mass issue-based, affective (emotional/tribal), and geographic dimen

Are Ultra-Processed Foods a Public Health Hazard? The scientific consensus is increasingly leaning toward yes — a growing and substantial body of evidence links ultra-processed food (UPF) consumption to numerous adverse health outcomes, though the debate about mechanisms, causation, and the classification system itself is still active. The Evidence for Harm Scale of the problem: The U.S. is a

Short answer: Voter fraud exists in the U.S., but measured rates are very low. It occasionally affects very close local races; there’s no credible evidence of widespread fraud altering national outcomes. What the best evidence shows - Measured incidence: Multiple large reviews have found extremely small rates of individual voter fraud. For example, one review found 31 credible cases of in‑person

An overwhelming and rapidly growing body of scientific evidence, paired with major shifts in global nutrition policy, points to ultra-processed foods (UPFs) as a severe and pressing public health hazard. UPFs dominate modern diets. In nations like the United States and the United Kingdom, they account for roughly 50% to over 65% of the average person's daily calorie intake, with children and ado

Short answer: Probably yes—at least at current levels of consumption—though there’s nuance. Why many experts view UPFs as a population-level hazard - Widespread exposure: In the U.S., roughly 58% of adults’ calories came from foods classified as ultra-processed in 2017–2018, so even modest harms scale up. ([jn.nutrition.org](https://jn.nutrition.org/article/S0022-3166%2822%2911001-1/fulltext?utms

Short answer: Yes, the weight of evidence strongly suggests they are — though some scientific debate remains about why. The case that UPFs are a public health hazard Scale of exposure. UPFs now make up a huge share of diets in many countries. More than half of the calories that the average American adult consumes are from ultra-processed foods. The U.S. is among the biggest consumers of UPF in

An overwhelming body of scientific evidence suggests that ultra-processed foods (UPFs) represent a major global public health hazard. While they offer convenience, affordability, and a long shelf life, their high consumption is systematically linked to a wide range of chronic illnesses, mental health disorders, and early death. Globally, UPFs make up a massive portion of modern diets—often accou

Yes, in several key measurable ways—particularly over the past several decades—political polarization in the United States is worse (or at least higher) than it has been in the recent past, though comparisons to deeper history are more nuanced and it is not uniformly “worse than ever” across all dimensions or eras. Polarization is multi-faceted (ideological/issue-based, affective/emotional, elite

The question of whether Russia’s invasion of Ukraine is justified depends on the perspective being examined. The Russian government has presented several security, political, and historical justifications for its actions. Conversely, the overwhelming consensus of international bodies, legal experts, and foreign governments is that the invasion is a clear violation of international law and is entir

No, Russia's full-scale invasion of Ukraine (launched on 24 February 2022) is not justified under international law, and its primary stated rationales do not hold up to factual or legal scrutiny. It constitutes a clear violation of the UN Charter’s prohibition on the use of force against the territorial integrity or political independence of any state (Article 2(4)). The overwhelming majority of s

Under international law, and by the overwhelming consensus of the global community, Russia’s invasion of Ukraine is considered unprovoked, illegal, and unjustified. However, the Russian government has put forward several arguments to justify its military actions. To understand the debate surrounding the justification of the invasion, it is necessary to examine the consensus under international l

Short answer: Yes, the evidence strongly suggests ultra-processed foods (UPFs) pose significant public health risks — though important debates remain about mechanisms and whether all UPFs are equally harmful. The evidence is substantial and growing Large-scale reviews consistently link high UPF consumption to numerous chronic diseases. A 2024 umbrella review of 45 meta-analyses including almos

The short answer is: It depends on which "past" you are comparing it to. If you compare today’s political environment to the mid-to-late 20th century (the post-WWII era), yes, political polarization is significantly worse and has reached levels not seen in living memory. However, if you look at longer-term American history—specifically the Civil War era of the 1850s and 1860s, or the Reconstruct

There is no single global set of binding rules for AI systems like large language models (LLMs), generative AI, or frontier models. Instead, a fragmented landscape of hard law (statutes and regulations), soft law (voluntary frameworks and standards), executive actions, industry commitments, and existing general laws (e.g., product liability, tort, privacy, consumer protection) applies. These gover

Short answer: Largely yes—at the population level, high consumption of ultra-processed foods (UPFs) is now considered a genuine public health concern. The strongest recent synthesis, a 2024 BMJ umbrella review of meta-analyses, found direct associations between higher UPF intake and a wide range of adverse outcomes (32 distinct health endpoints), including overall mortality and cardiometabolic, me

To answer whether political polarization is "worse than it has been in the past," political scientists and historians look at different eras, measurements, and definitions. The short answer is yes, political polarization is worse than it has been in any living person’s memory (dating back to the mid-20th century). In terms of how much Americans dislike one another based on party lines, we are at

Whether political polarization is "worse" today than in the past depends on how polarization is measured and which era of history is used as a comparison. If compared to the mid-20th century, the United States is indeed experiencing a historic, unprecedented peak in division. However, if compared to the entire span of American history, the country has survived eras of equal or greater division—m

Short answer: Yes. Given how much of the population’s calories come from ultra‑processed foods (UPFs) and the consistency of links to major diseases, high UPF intake is best treated as a public‑health hazard, even as scientists continue to refine definitions and causal mechanisms. In the U.S., UPFs supply roughly 55–60% of daily calories and have increased over time, so even modest per‑person risk
