Polora Picks

Short pieces on the questions people actually ask at work, written by Polora's editors and checked by several AI models before they reach you. Each pick keeps the full record of that check.

  1. Is Intel still the biggest US chip company? By revenue, it is now fourth of six Business & Economy

    Of six large US chip companies, Intel brought in the most revenue every quarter from 2019 through 2022. By early 2026, Nvidia, Broadcom and Micron had all passed it, and Nvidia's quarterly revenue was about six times Intel's.

  2. Has every month's hottest on record come since 2023? Science & Health

    Yes. In NASA's global temperature record, which goes back to 1880, each of the 12 calendar months had its warmest reading in 2023 or later. The 12 warmest full years are the last 12, 2014 to 2025.

  3. Why are so many cruise ships registered in Panama, Liberia or the Bahamas? Business & Economy

    Mostly because a US flag would bring US shipbuilding and US crewing rules. The flag country is mainly responsible for checking a ship's safety, and other countries' ports inspect it too. Whether a cruise company pays US tax on its shipping income depends mostly on where the parent company is incorporated.

  4. Why did baseball games get shorter? A century of drift, then a pitch clock Culture & The Arts

    A nine-inning big-league game took 1 hour 48 minutes in 1920 and 3 hours 10 minutes in 2021. In 2023, the first season with a pitch clock, games lost 24 minutes, by far the biggest one-season drop since 1920, even though batters struck out about as often as before.

  5. Since 2000, US pay rose 137%. Which prices rose faster? Business & Economy

    Average hourly pay for most US private-sector workers has more than doubled since January 2000, faster than prices overall. Hospital care, tuition and childcare, car repair, rent, eating out and gasoline all rose faster than pay, while toys got cheaper and clothes barely moved.

  6. What happens to the clothes you drop in a donation bin? Business & Economy

    Only part is resold nearby. The rest is sorted, sold by the kilo and often shipped abroad in bales, where many clothes are worn again. What those kilos fetch has long helped pay for the bin on your street.

  7. How did coal fall from half of US electricity to about a sixth? Science & Health

    Natural gas first, then wind and solar. Coal fell from 52% of US electricity in 2000 to 16% in 2025; gas took the top spot in 2016, and wind and solar together passed coal in 2024.

  8. Is the poop you pass today from last night's dinner, or from something you ate days ago? Science & Health

    Usually from meals eaten a day or more ago, mixed together. In studies of healthy adults, the first trace of a meal usually took over a day to appear. The urge after eating is your colon moving out what was already there.

  9. What is the white crust on old batteries, and why do dead or unused ones leak? Science & Health

    On an ordinary alkaline AA it isn't acid. It is leaked alkaline liquid that the air has turned into a salt. Dead cells can leak when current is forced through them, and heat and age can make unused ones leak too.

  10. Are there now more US jobs in health care than in factories? Business & Economy

    Yes, by 5.9 million. In September 2026 health care counted 18.6 million US jobs to manufacturing's 12.7 million. Health care pulled ahead in September 2008 and has stayed ahead every month since, though in January 1990 factories had more than twice as many jobs.

  11. Does IKEA make its money selling furniture, or selling the IKEA name? Business & Economy

    Both. The company that owns the IKEA name rarely runs the stores. It charges them 3% of their sales, but takes in far more by selling them the goods, and does not say which of the two earns it more profit.

  12. Who really makes money from the Olympics, the host city or the IOC? Business & Economy

    The IOC has the safer income. It sells TV rights and global sponsorships years ahead, while public bodies in the host country pay for venues, transport and security. Paris 2024's organisers ended €75.7 million ahead, and France's auditors counted about €6.65 billion in public spending, most of it by the national government.

  13. Do airports make more money from parking and shops than from airlines? Business & Economy

    Not overall. Airlines still pay the larger share worldwide and across US airports, though not at every airport. Of the 44% that US airports earn from other sources, parking and ground transport come first, far ahead of the shops.

  14. Who decides when a new word gets into the dictionary? Culture & The Arts

    No committee votes on new English words. Dictionary editors add a word once they see wide use over several years and judge the evidence strong enough. An entry records how a word is used. It does not certify the word as correct.

  15. Is a Big Mac more expensive than in 2014, once you count inflation? Business & Economy

    Barely. The Economist recorded a US Big Mac at $4.29 in July 2014 and $6.22 in July 2026; adjusted for consumer prices overall, that is only 3.4% more. The real jump came between 2005 and 2014, and since then the price has roughly kept pace with inflation.

  16. Who actually decides what you pay for a prescription at the pharmacy? Science & Health

    No single party decides it. For an insured prescription, the price comes out of contracts among the drug maker, your health plan and the pharmacy benefit manager the plan hires, and the plan's choice of copay, deductible or coinsurance shapes your share most directly. If you are paying toward a deductible or a percentage of the price of a brand-name drug, your share is often figured on the price rung up at the counter, which follows the list price, not on the lower price your plan pays after rebates.

  17. Why does Starbucks hold over a billion dollars of customers' money? Business & Economy

    Because money loaded onto a Starbucks card or the app is paid before any coffee is made, and Starbucks books it as a debt it repays in drinks. In June 2026 that debt, counted together with unspent rewards points called Stars, stood at about $1.7 billion. Card balances earn customers no interest and carry no deposit insurance.

  18. Who actually decides your credit score? Business & Economy

    Private companies build the scores lenders use. FICO is one, and VantageScore, owned by the three credit bureaus, is the other. Lenders choose which score to use. For many mortgages, a federal agency sets which scores are allowed.

  19. How much has the $7.25 federal minimum wage lost since 2009? Business & Economy

    Since July 2009, the federal minimum wage has stayed at $7.25 an hour, and rising prices have taken away 36% of what it buys. It is the longest the floor has ever gone without a raise, and before 2026 it had not been worth this little since 1949.

  20. Has working from home gone back to 2019 levels? Business & Economy

    No. In September 2026, US workers in a large monthly survey still worked about 27% of their full paid workdays from home, nearly four times the 2019 level. That is far below the 2020 peak, and the decline has slowed to about a point a year since 2022.

  21. Are eggs cheaper now than in 1980, after inflation? Business & Economy

    Yes. In August 2026 a dozen eggs averaged $2.27 in US cities, which after inflation is less than in any month of 1980. For the average production and nonsupervisory worker, a dozen also took about half as many minutes of hourly pay as in January 1980.

  22. How many people live where fertility is below 2.1? By 2023, two-thirds Science & Health

    By 2023, 67.1% of people lived in a country where the fertility rate was below 2.1 children per woman, roughly the level at which each generation replaces the last. In 1960 it was 3.9%. Most of that rise came in two single years : 1991, when China crossed the line, and 2020, when India did.

  23. Why were seven of America's ten biggest cities in California, Texas or Arizona by 2020, when in 1950 only one was? Business & Economy

    Counted inside city limits, the way the census counts cities, the top ten moved south and west after the Second World War. Part of that, the Census Bureau says, is where city lines are drawn : most of the rising cities took in a lot of land, and counted by whole metro areas, only three of the ten largest are in those states.

  24. Where does Amazon's profit come from? Mostly the cloud, not the store Business & Economy

    Mostly from Amazon Web Services (AWS), its cloud business. In 2025, AWS brought in 18% of Amazon's sales but 57% of its operating income. In three of the years between 2014 and 2025, the cloud earned more than the whole company, which means everything else at Amazon, taken together, lost money.

  25. How did a memory-chip maker's gross margin overtake Nvidia's? Business & Economy

    Mainly through higher memory prices, Micron says, driven by AI demand it describes as outpacing what the industry can supply. By mid-2026 Micron kept about $85 of gross profit from every $100 of sales, a level Nvidia did not reach in any of its quarters in this data, which starts in 2008. In early 2023, Micron's cost for the chips it sold, swollen by a write-down of chips still in stock, was bigger than its sales.

  26. Does Disney make more money from its theme parks than from its movies? Business & Economy

    Yes, by a wide margin. In fiscal 2025, Disney's parks, cruises and merchandise earned $10.0 billion in operating income, more than twice the $4.7 billion from film, TV and streaming combined. Disney does not report a profit figure for movies alone.

  27. Is Guinness World Records paid by the companies that break its records? Business & Economy

    Not for the verdict, Guinness says. Individuals chasing a record for themselves can apply free, but brands must pay : for help choosing a record, a judge or the logo. An executive said in 2023 that this work brings in about half its revenue.

  28. How does U.S. News decide which colleges rank best? Business & Economy

    By a weighted formula it keeps revising. For national universities, 52 percent is how students fare after enrolling, 20 percent is college leaders rating rival schools, and acceptance rate counts for nothing.

  29. Do brands pay supermarkets to get their products on the shelf? Business & Economy

    Yes, though not every store or product. A US chain may ask a brand to pay just to stock a new product, and the brand may then fund its discounts and displays. Trader Joe's says it charges no such fee.

  30. Does a hurricane's category tell you how dangerous it is? Science & Health

    Not really. The category, 1 to 5, rates only a hurricane's strongest sustained wind, while roughly eight to nine in ten people killed directly by US hurricanes since 1963 died in water : rain floods, storm surge and surf.

  31. Why does printer ink cost more than the printer? Business & Economy

    For HP, the money is in the refills. Its then chief executive said it loses money on printers and earns it on supplies such as ink and toner, which bring in about two thirds of its printing revenue.

  32. Do gas stations make money selling gas? Business & Economy

    Yes, but only cents : a US industry group puts what a station keeps at 10 to 15 cents a gallon before tax. The store earns most of the gross profit, yet in 2025 fuel kept stores profitable.

  33. Is a diamond still worth what you paid for it? Business & Economy

    Usually it never was. A diamond bought in a shop has long sold back for a fraction of its price, because the shop price carried a retail markup, while anyone buying it back pays wholesale or less. Separately, De Beers, the company that long controlled most of the world's diamond supply, held the price level up. Lab-grown stones have weakened that system, and De Beers is up for sale.

  34. How accurate is the calorie count on a food label? Science & Health

    It is usually an estimate, not a measurement. Label calories are typically calculated from protein, carbohydrate and fat using per-gram factors from around 1900. The US test for packaged food fails a product only when a sample drawn from a batch holds more than 20 percent more calories than the label states. Fewer calories than stated does not fail that test.

  35. Is McDonald's really a burger company, or a landlord that sells burgers? Business & Economy

    Both. In 2025 McDonald's reported $10.4 billion in rent from franchisees against $6.0 billion in royalties, but that rent is tied to how many burgers its restaurants sell.

  36. Does a 90% on Rotten Tomatoes mean critics think a movie is great? Culture & The Arts

    No. A 90% means 9 in 10 counted critics leaned positive, however mildly. A film most critics call merely fine can outscore one half of them call a masterpiece.

  37. How do free mobile games make money when almost nobody pays? Business & Economy

    Largely from a tiny group of big spenders, plus ads. In a 2016 study of tens of millions of players, 1.9 percent bought anything in a month, and 0.19 percent brought in 48 percent of purchase revenue. Ads earn from many who never pay, and the mix varies by game.

  38. Is a product labeled 'Made in Italy' actually made in Italy? Business & Economy

    Partly. Under EU rules, 'Made in Italy' names the country where the last substantial stage of manufacture took place, not a mere finishing touch. A shirt sewn in Italy from imported fabric can carry it.

  39. How does a book become a New York Times bestseller if it isn't just about sales? Culture & The Arts

    Sales count, but the Times decides how. It surveys stores it won't name, weights them by a formula it doesn't publish, skips some kinds of books and judges bulk buying.

  40. Who decides when a recession has officially started? Business & Economy

    In the US, no government agency does. A committee of eight academic economists at a private nonprofit, the National Bureau of Economic Research, names the month a recession began. It does not use the 'two quarters of falling GDP' rule, and it names the month only after the fact, often many months later.

  41. Why does a tire company decide which restaurants get Michelin stars? Culture & The Arts

    Because Michelin started the guide in 1900 to get French drivers on the road and wearing out tires, and never let it go. Today, in many newer places, tourism boards help pay for the guide to come, after Michelin judges the local dining worth a look. Michelin says the stars themselves are not for sale.

  42. How do stock apps make money if trading is commission-free? Business & Economy

    Mostly not from the free stock trades. In 2025, Robinhood made $302 million from stock trades out of $4,473 million in revenue. Option orders, crypto, and interest on loans and idle cash earned far more.

  43. How does a bank make money on a free checking account? Business & Economy

    Mostly by paying almost nothing on your balance. In September 2026 US interest checking averaged 0.07 percent while short-term Treasury debt paid around 3.6 percent. That gap, plus card and penalty fees, is what pays for most free accounts.

  44. Who decides which companies get into the S&P 500? Business & Economy

    A committee of S&P Dow Jones Indices staff decides. Published rules on size, profit and share trading set who may normally be considered. The committee chooses from that pool, can pass over a company that meets every rule, and does not apply the entry rules to companies already inside.

  45. Why is a big smart TV so cheap now? Business & Economy

    The broad reason is that, over the long run, the screen inside became much cheaper to make. Some brands also earn money after the sale, from home-screen ads and viewing data. In 2024 Vizio's TVs and sound bars made a gross loss, and its profit came from that second business.

  46. Do car dealerships actually make money selling new cars? Business & Economy

    Yes, but it is a small share of their profit. At AutoNation, a large US dealer group, new cars brought in almost half of 2025 revenue but only 13.4% of gross profit. Repairs and service made 47.6%, and loans and warranties sold with the car most of the rest.

  47. How do gyms make money when most members barely show up? Business & Economy

    A low-cost gym sells far more memberships than it has room for at one time, because members come at different hours and some rarely come at all, while the dues arrive either way. At Planet Fitness, the company behind the brand also takes a royalty on franchise clubs' dues and fees, 7% under its current agreement, and sells them their equipment.

  48. Does Coca-Cola actually make the Coke you drink? Business & Economy

    Usually not, for a can or bottle. In most countries a separate bottler mixes, fills and delivers it with Coca-Cola's concentrate, and Coca-Cola keeps the more profitable part.

  49. 회식 삼겹살은 막내가 구워야 할까, AI 넷의 토론에서는 누가 이겼을까? AI & Society

    심판 AI 제미나이는 혼자 ‘막내가 굽는다’를 편 키미에게 1위를 줬습니다. 나머지 셋은 모두 ‘잘 굽는 사람이 굽는다’ 편이었고, 제미나이도 현실의 집게는 그쪽에 주라고 덧붙였습니다.

  50. 여러 AI에게 동시에 묻는 서비스, AI끼리 토론시키려면 어디가 맞을까? AI & Society

    AI끼리 토론시키는 게 목적이라면 실험 속 AI 모델들은 대부분 폴로라를 꼽았습니다. 답을 나란히 비교하려면 ChatHub, 개발자라면 OpenRouter Fusion이었습니다. 폴로라 운영자가 폴로라에서 돌린 실험입니다.
