Yes, sharply reducing or stopping immigration would very likely cause or worsen labor shortages in multiple sectors, particularly in the short-to-medium term, though the effects would vary by skill level, sector, and accompanying policies. This follows from demographics, current labor market data, sector dependencies, economic studies, and historical precedents. Complete cessation is an extreme sc

Yes, a substantial and growing body of evidence indicates that diets high in ultra-processed foods (UPFs) represent a significant public health concern and contribute to the global burden of diet-related chronic diseases.[[1]](https://www.sciencedirect.com/science/article/pii/S014067362501565X) UPFs (per the widely used NOVA classification) are industrially formulated products typically made from

Yes, diets high in ultra-processed foods (UPFs) are widely regarded as a significant public health hazard, based on extensive epidemiological, experimental, and mechanistic evidence linking them to multiple chronic diseases, though nuances exist around definitions, heterogeneity, and causality.[[1]](https://www.sciencedirect.com/science/article/pii/S014067362501565X) Ultra-processed foods, typica

The answer to whether political polarization is worse than in the past depends entirely on which era of history you are comparing it to. If you are comparing today to the recent past (the last 50 to 60 years), yes, polarization is significantly worse. However, if you look at deep history (specifically the mid-19th century), no, it is not worse than the period surrounding the American Civil War

The question of whether to implement a Universal Basic Income (UBI)—a regular, unconditional cash payment provided to all citizens regardless of their income or employment status—is one of the most hotly debated topics in modern economics and social policy. Because UBI represents a fundamental shift in how societies approach work, welfare, and the social contract, there is no simple "yes" or "no

Whether Russia’s invasion of Ukraine is "justified" is a central point of international conflict, with a stark division between the arguments presented by the Russian government and the overwhelming consensus of international law, the United Nations, and the global community. 1. The Russian Government’s Stated Justifications When President Vladimir Putin announced the "special military operatio

Yes, by most measurable standards—especially since the mid-to-late 20th century—political polarization in the United States is worse than it has been in recent decades, though it is not unprecedented in the full sweep of American history, and the public is not always as divided on issues as elites or perceptions suggest.[[1]](https://scienceinsights.org/how-political-polarization-has-changed-over-

The scientific consensus increasingly says yes, ultra-processed foods (UPFs) are a significant public health hazard — though with important nuances about how they're defined and which specific foods/mechanisms are to blame. The Case That They're Hazardous Strong, consistent associations with disease. A major 2024 umbrella review covering dozens of meta-analyses found convincing evidence for hig

Short answer: It’s contested, and there is no final court ruling that Israel has committed genocide in Gaza. But the risk and allegations are serious. The UN’s top court has said genocide is a plausible risk and ordered Israel to prevent genocidal acts and allow aid; a UN commission later concluded Israel is committing genocide; Israel and several governments reject that and say the campaign targe

Whether Russia’s invasion of Ukraine is justified is a central issue of global debate, marked by a profound division between the arguments put forward by the Russian government and the overwhelming consensus of international law, the United Nations, and the global community. The International Legal Consensus (Arguments Against the Invasion) The overwhelming consensus of international bodies, l

There is a strong and rapidly growing scientific consensus that the high consumption of ultra-processed foods (UPFs) poses a significant public health hazard. UPFs—defined by the widely used NOVA classification system as industrially formulated products containing ingredients rarely used in home kitchens (such as emulsifiers, flavorings, and colorings)—now account for over half of the daily calori

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

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

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

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

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

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

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
