Short answer: Yes, in most measurable ways—especially among political elites and in terms of partisan animosity—but the picture is nuanced depending on how you define "polarization" and what time period you compare to. Where the evidence strongly supports "worse than before" Congress/elites: A Pew Research Center analysis finds that, on average, Democrats and Republicans are farther apart ideo

Social media is neither purely more harmful nor more helpful—it is a double-edged tool whose net impact depends heavily on how it is used, by whom, how much, the specific platforms/content, and individual circumstances. Research (including multiple meta-analyses, longitudinal studies, experiments, and large surveys) consistently shows small average effects overall, with both benefits and risks tha

Yes, by most standard measures, political polarization—particularly in the United States—is worse now than it has been in recent decades (post-World War II era), though it is not unprecedented in American history when compared to extreme periods like the Civil War era, and trends vary by type of polarization and country.[[1]](https://www.cam.ac.uk/stories/political-division-united-states) Polariz

Yes, the weight of current scientific evidence strongly suggests ultra-processed foods (UPFs) are a public health hazard — though important debates remain about why they're harmful and how to define them precisely. What the evidence shows Large-scale reviews consistently find associations with poor health outcomes. The most cited umbrella review, published in The BMJ in 2024, came from a review

Yes, in several key measures—especially in the United States—political polarization is worse now than in recent decades (post-WWII or since the 1970s–1980s), though it is not unprecedented in American history and trends vary by type of polarization, country, and metric.[[1]](https://phys.org/news/2026-02-political-division-surged-onward.html) Polarization has multiple dimensions: ideological/issu

The U.S. political climate in late 2026 (amid a second Trump administration and approaching midterms) is marked by extreme polarization, eroded trust in institutions, economic pressures, and heightened risks of democratic strain, violence, and instability. These threats are interconnected and viewed very differently across the political spectrum—Democrats and progressives often emphasize authorita

Yes — the scientific consensus is strong and growing The evidence that ultra-processed foods (UPFs) pose a genuine public health threat has become substantially more robust and is now considered settled enough for coordinated policy action by major health bodies. The scale of the problem UPFs now dominate diets in many countries. The U.S. is among the biggest consumers of UPF in the world, an

I will look up current scientific consensus and evidence on ultra-processed foods and public health.I am reviewing key recent reviews and critiques for more detailed evidence.Yes, diets high in ultra-processed foods (UPFs) are widely regarded as a significant public health concern and hazard, based on extensive evidence linking them to poorer diet quality and elevated risks of multiple chronic dis

Social media is neither purely more harmful nor more helpful overall—it depends heavily on how it is used, by whom, how much, the specific platforms/content, and individual circumstances. Effects are typically small, bidirectional (use can influence well-being and vice versa), and highly variable. Scientific evidence from meta-analyses, umbrella reviews, and expert consensus reports does not suppo

Yes, AI chatbots are biased in multiple ways, including political, cultural, gender, racial, and other forms. This is extensively documented in academic studies, journalistic tests, and analyses of large language models (LLMs) that power tools like ChatGPT, Claude, Gemini, Grok, and others. Bias is not always intentional or extreme, but it arises inevitably from how these systems are built and tra

Yes — the accumulating scientific evidence strongly suggests that ultra-processed foods (UPFs) are a significant public health hazard, though some nuances and scientific debates remain about mechanisms and definitions. The Evidence Is Substantial and Growing Scale of consumption: UPF currently make up more than half of what U.S. adults eat on a daily basis, and two-thirds of what kids and teens
