“Being underweight in men causes a deficiency of dihydrotestosterone (DHT).”
Available evidence does not show that being underweight in men causes DHT deficiency. Research more commonly associates lower DHT with higher body fat or obesity, while underweight-related studies focus on hypogonadism or testosterone and do not directly demonstrate low DHT. The claim makes a specific causal statement that the cited evidence does not substantiate.
“U.S. golf courses used about 531 billion gallons of irrigation water in 2024 (about 1.63 million acre-feet of applied water).”
Available evidence supports the stated quantity. Multiple recent sources tied to the national GCSAA/USGA survey report about 1.63 million acre-feet of applied irrigation water in 2024, and that converts directly to roughly 531 billion gallons. The main caveat is terminology: this is applied irrigation water, not necessarily net consumptive water use.
“The European Commission fined AliExpress €550 million for breaching its obligations under the EU Digital Services Act.”
Official European Commission releases and multiple major news outlets report that the Commission imposed a €550 million DSA fine on AliExpress on 20 July 2026. The amount, regulator, company, and legal basis all match the claim. Any appeal would affect finality, not whether the fine was issued.
“More than $100 million has been invested in open source maintainers and projects through GitHub Sponsors.”
Available evidence supports the milestone. GitHub’s official blog, product pages, and documentation state that GitHub Sponsors has surpassed $100 million directed to open source maintainers and projects, and earlier milestones show a consistent growth path. The main limitation is that the total is platform-reported rather than independently audited.
“At least 10% of pilots believe that the Earth is flat.”
The evidence does not support the claim that at least 10% of pilots believe the Earth is flat. The commonly cited 10% figure refers to the general public, not pilots, and no reliable pilot-specific survey was provided. Sources discussing pilots indicate that their training and operational practice are based on Earth’s sphericity, making flat-Earth belief among pilots a fringe view, not a documented 10%+ share.
“Military historian Sir Basil Liddell Hart argued that relentless pressure applied by Australian forces forced Erwin Rommel to commit valuable reserves against them, weakening Axis defenses elsewhere.”
Reliable military-history sourcing supports the attribution. The best evidence directly reports that Liddell Hart argued Australian pressure compelled Rommel to use valuable reserves against them, reducing Axis strength in other sectors. The main caveat is that the support is presented chiefly through a secondary paraphrase rather than a verbatim primary quotation.
“Freestanding water is not readily available for lions in Kgalagadi Transfrontier Park, resulting in a lack of extra drinking water for lions.”
Natural surface water is indeed scarce in Kgalagadi, but the broader claim is misleading. Reliable sources show the park maintains many artificial borehole-fed waterholes that provide freestanding drinking water and are used by lions. So the evidence supports aridity and limited natural water, not a general lack of accessible extra drinking water for lions.
“In a linear regression model, correlation between two predictor variables can be accommodated by the model without necessarily causing a problem.”
The claim is well supported. Correlated predictors do not automatically violate linear regression assumptions or make OLS estimates biased, and many models handle moderate correlation without serious practical difficulty. The real concern is severe or near-perfect multicollinearity, which can inflate standard errors and make individual coefficients unstable, especially for inference.
“A woman was killed after a man fell from a 12-story building, landed on her, and survived the fall.”
Multiple reliable news outlets consistently reported that a man fell from a 12-story building in Nagoya, struck a woman below, and remained alive after the impact while she died. The reporting is independently corroborated across major outlets. The main caveat is that he was reported in critical condition, so the evidence confirms immediate survival of the fall, not necessarily long-term recovery.
“More than 105 million Americans are not in the labor force and are not looking for work.”
Current BLS data support the figure. In June 2026, the main seasonally adjusted household survey estimates showed about 105.8 million people not in the labor force, and that category means they were not employed and not actively seeking work during the reference period. One not-seasonally-adjusted BLS table falls just below 105 million, but that does not materially change the overall takeaway.
“Insulin therapy causes weight gain in people with diabetes.”
Clinical evidence consistently identifies insulin therapy as a common cause of weight gain in diabetes. Major guidelines and reviews describe several mechanisms, including reduced calorie loss in urine, anabolic effects, and compensatory eating to avoid hypoglycemia. The effect is not inevitable, and its size varies by regimen and lifestyle, but those caveats do not change the main conclusion.
“Domestic dogs (Canis lupus familiaris) have hair.”
Veterinary and scientific literature treats the dog coat as hair produced by hair follicles. The common “hair versus fur” distinction is mostly colloquial, not an anatomical contradiction. Rare hairless breeds are exceptions in appearance, not evidence against the species-level fact.
“In ducks with egg binding, inability to lay an egg and inability to pass feces can occur simultaneously and the duck’s condition can rapidly worsen.”
The evidence supports this as an emergency pattern seen in egg-bound ducks. Veterinary references indicate a retained egg can prevent laying and also reduce or stop fecal passage, and they warn that affected birds may deteriorate rapidly without treatment. The exact timeline and severity vary, but the core claim is well supported.
“Ducks have a cloaca through which both feces and eggs pass.”
Authoritative anatomy sources support that ducks have a cloaca, and both feces and eggs pass through it at different times. Some internal structures help keep egg-laying and fecal passage functionally separated, but that does not change the basic fact that both use the cloacal outlet.
“Copper surfaces kill bacteria through contact (without additional disinfectants).”
The evidence strongly supports that copper surfaces can kill bacteria through intrinsic contact-mediated antimicrobial action, without needing added disinfectants. EPA registrations and multiple mechanistic studies show the effect is built into the copper surface itself. The main caveat is that performance depends on conditions such as cleanliness, alloy type, and sufficient contact time.
“A 2018 Massachusetts Institute of Technology (MIT) study found that false stories spread six times faster than true stories on Twitter and were retweeted 70% more often.”
The claim is well supported by the 2018 Science study and accurate summaries from MIT and Reuters. The study found false news was about 70% more likely to be retweeted and that truth took roughly six times as long as falsehood to reach 1,500 people on Twitter. The "six times faster" phrasing is shorthand for that specific diffusion benchmark.
“Dinosaurs are birds and lizards.”
The claim is not supported by modern taxonomy. Birds are living dinosaurs, but dinosaurs are not simply “birds,” because only one dinosaur lineage survives as birds. Dinosaurs are reptiles within Archosauria, whereas lizards belong to a different reptile branch, Squamata, so calling dinosaurs “lizards” is scientifically wrong.
“Saudi Arabia's 2024 adult-skills statistics report high participation by young people in formal and non-formal education and training.”
Official Saudi statistics support this characterization. The 2024 adult-skills publication reports 64.76% participation among youth aged 15–24 in formal and non-formal education and training, well above the 29.23% rate for the broader 15–64 population. The main caveat is that “high” is a qualitative description, not a defined benchmark or cross-country ranking.
“Official graduate statistics show that Saudi Arabia produces a sizeable number of bachelor's degree graduates, alongside master's, higher-diploma, and doctoral graduates.”
Official Saudi education statistics do show large numbers of bachelor’s graduates as well as higher-diploma, master’s, and doctoral graduates. The strongest support comes from Saudi government datasets and related official statistical publications, not from a single postgraduate-only table. The claim is accurate, with only a minor caveat that “sizeable” is a qualitative term rather than a fixed threshold.
“Saudi Arabia's education policy explicitly links the establishment of foreign university branch campuses in Saudi Arabia to expertise transfer and to Saudi labour-market demand under Saudi Vision 2030.”
The evidence largely supports this claim. Saudi education policy explicitly ties foreign branch campuses to workforce development and national priorities associated with Vision 2030, while official Ministry of Education policy also explicitly treats international university cooperation as a channel for academic expertise transfer. The main caveat is that these links are spread across several policy instruments rather than stated together in one document.
