“Catherine, Princess of Wales, is a member of the British royal family.”

Authoritative official and independent sources consistently identify Catherine, Princess of Wales, as part of the British royal family. The claim matches both official royal communications and standard usage in major news and reference works. Any debate over a formal legal definition of “membership” does not change the practical and publicly recognized reality.

“The SARS-CoV-2 Omicron XBB subvariant is lethal and is not easy to detect.”

The claim overstates both the danger and the diagnostic difficulty of XBB. Authoritative human data show XBB was not unusually deadly compared with other Omicron lineages, even though severe illness and death could still occur in high-risk people. Standard COVID-19 tests continued to detect XBB; only some specific assay targets or variant-tracking markers were affected.

“An 81-year-old couple renewed their wedding vows inside a Taco Bell restaurant to celebrate their 60th wedding anniversary.”

Multiple credible news outlets and broadcast footage consistently report that an 81-year-old Utah couple renewed their vows inside a Taco Bell to mark their 60th wedding anniversary. The key details in the claim match across those reports. Most social-media posts are just reposts, but they are not needed to support the claim.

“Potassium bromate is banned as a food additive in Ghana.”

Potassium bromate is legally prohibited for use as a food additive in Ghana. Peer‑reviewed Ghana-specific research repeatedly states that Ghana banned potassium bromate for bread-making/dough conditioning (often dated to 1997) and describes it as prohibited under Ghana Standards Authority/FDA regulatory context. Reports of continued clandestine use reflect enforcement problems, not the absence of a ban.

“Telling small self-serving lies can desensitize a person and increase the likelihood that the person will tell bigger lies later.”

Evidence strongly supports a real slippery-slope effect in dishonesty. Experimental studies show that small self-serving lies can be followed by reduced emotional sensitivity and a higher chance of telling larger lies later. The main caveat is that the strongest evidence comes from controlled research settings, so the effect is best understood as a demonstrated tendency, not an inevitability in every person or situation.

“Sitting on a cold floor causes ovarian health problems.”

The evidence does not support the claim. Authoritative human health sources do not recognize sitting on a cold floor as a cause of ovarian problems, and available studies showing ovarian effects involve prolonged whole-body cold exposure in rodents, not ordinary human contact with a cold surface. The claim relies on a folklore-style extrapolation rather than demonstrated human evidence.

“Ethanol-blended gasoline is harmful for vehicles used in India.”

The evidence does not show that ethanol-blended petrol broadly harms vehicles in India. Authoritative sources indicate E20 is generally safe for E20-compatible vehicles and has not been shown to cause widespread engine damage, though some older or non-compatible vehicles can see modest mileage loss and may need certain parts checked or replaced. The claim contains a narrow truth for a subset of vehicles but overstates it into a general rule.

“The Bogalusa Heart Study was a long-term study that followed children's cardiovascular health into adulthood and found evidence that cardiovascular disease can begin in childhood.”

The evidence strongly supports this description of the Bogalusa Heart Study. It was a long-running longitudinal study that followed children into adulthood, and its autopsy and follow-up findings helped show that atherosclerotic cardiovascular disease processes can start in childhood. The wording is appropriately cautious because it refers to evidence of early disease development, not typical childhood heart attacks.

“About 16,000 children participated in the Bogalusa Heart Study over about 40 years.”

The evidence does not support the claim as stated. Reliable sources consistently report more than 12,000 children in the Bogalusa Heart Study, while the figure above 16,000 refers to total participants overall. The study also spans roughly 50 years since 1973, although some older descriptions referred to nearly 40 years of follow-up.

“In the Bogalusa Heart Study, about 25% of participants reached a healthy weight as adults and about 75% remained overweight or obese.”

The evidence does not support the claimed 25%/75% adult weight split in the Bogalusa Heart Study. Cohort-wide figures cited in the underlying literature are far lower than 75% overweight/obese in adulthood, including about 42% in one young-adult analysis and 57.7% overweight in another follow-up measure. The claim appears to misread subgroup tracking results as if they described all participants.

“In the 1970s, about 5% of children in the United States were obese, and at the time a referenced documentary was made, about 17% of children in the United States were obese.”

The historical comparison is broadly accurate. CDC data put U.S. childhood obesity at roughly 5% in the early 1970s and about 17% in 2009-2010, a figure widely cited at the time. The caveat is that the 17% number depends on when the documentary was made; later estimates were higher.

“About one-third of Americans have excess liver fat.”

The broad takeaway is supported: recent U.S. evidence commonly places fatty liver in roughly 30% of adults, making “about one-third” a reasonable shorthand. The strongest support comes from national survey analyses and review articles showing prevalence near that level. The claim is not fully precise because estimates vary by definition and testing method, and many studies measure adults rather than all Americans.

“Cheap synthetic underwear fabrics such as pure polyester or nylon trap sweat and bacteria against the skin more than cotton underwear does.”

The evidence strongly supports the core takeaway that cotton underwear is generally less likely than pure polyester or nylon to hold sweat and foster odor-related bacterial buildup next to the skin. Clinical guidance and textile studies consistently favor cotton for breathability and moisture control. The main caveat is that fabric blends, knit structure, and moisture-wicking treatments can affect performance.

“Shah Rukh Khan and Priyanka Chopra had an extramarital affair.”

Available evidence does not establish that Shah Rukh Khan and Priyanka Chopra had an extramarital affair. Credible reporting describes the story as longstanding rumor and speculation, with no independent confirmation and with denials or contrary characterizations from those involved. Gossip coverage and third-party impressions are not enough to turn an allegation into a verified fact.

“In pre-revolutionary France, society was divided into three estates: the First Estate (clergy), the Second Estate (nobility), and the Third Estate (common people).”

The evidence strongly supports this standard description of ancien régime France. Authoritative historical sources consistently identify the First Estate as clergy, the Second Estate as nobility, and the Third Estate as everyone else. The only notable nuance is that the king stood outside or above the estates, which does not change the basic accuracy of the claim.

“In the Estates-General of France, each of the three Estates had one vote, allowing the First Estate and Second Estate to outvote the Third Estate.”

The historical evidence supports the claim’s core point. Under the traditional Estates-General system, each estate voted as a bloc, so the clergy and nobility could outvote the Third Estate two votes to one. The important caveat is that in 1789 this procedure was disputed, which became a major cause of the political crisis.

“In the late 1780s, the Kingdom of France was nearly bankrupt due to the costs of expensive wars and high government spending.”

The claim is well supported by mainstream historical scholarship. By the late 1780s, the French monarchy faced acute fiscal distress driven in large part by debts from major wars and the burden of state spending, especially interest and military costs. France’s problem was not just the size of debt, but its weak ability to raise revenue and maintain credit.

“Poor harvests in France in the late 1780s contributed to food shortages and rising bread prices in France.”

The evidence strongly supports this link. Multiple high-quality historical sources state that poor harvests in the late 1780s, especially 1788, reduced grain supplies in France and drove bread prices sharply upward, worsening food shortages. Other economic and political factors were also involved, but the claim only says harvests contributed, which is accurate.

“In 1788–1789, France experienced severe weather that contributed to crop failures and social unrest.”

Historical evidence strongly supports that France suffered major weather shocks in 1788–1789, including drought, hail, and an unusually harsh winter. These events damaged harvests, tightened grain supplies, raised bread prices, and helped fuel riots and rural unrest. Weather was a contributing factor, not the only cause of the broader revolutionary crisis.

“A climate-action blueprint attributed to David Attenborough calls for rapidly transitioning from fossil fuels to clean energy.”

The underlying message is well supported: David Attenborough has clearly called for moving quickly from fossil fuels to clean energy. But the claim overstates the format of that message by presenting it as a distinct “climate-action blueprint,” which reliable sources do not clearly establish. The result is a substantively accurate point wrapped in a misleading description.
