Corrections Policy

Last updated: 12 September 2026

We get things wrong sometimes. When we do, we fix the guide and say what changed. Mistakes that could have misled a reader are listed at the bottom of this page.

How to report a mistake

Email us at leadingfolks(at)gmail.com, or see our contact page. It helps if you include:

• the address of the page
• the sentence you think is wrong
• a source that shows the right answer, if you have one

If you are under 13, please ask a grown-up to send the report for you. Grown-ups, please do not include a child’s full name, age or school.

What happens next

1. We read the passage and the sources it relies on. If they do not settle it, we look for a better source.
2. If the guide is wrong, we correct it. We also check the rest of the guide for the same mistake, because a wrong figure is often repeated.
3. We change the guide’s “Updated” date.
4. If the mistake could have misled a reader, we add it to the list below with the date and what changed.
5. If the guide was right, we may still reword it so the evidence is clearer.

Corrections, updates and small fixes

• Correction. A fact, figure, date or name was wrong, a claim had no reliable source, or a picture showed something different from its caption. Listed below.
• Update. A newer discovery or count replaced a figure that was right when we wrote it. Listed below when the change matters to a reader.
• Small fix. Spelling, formatting and broken links. Fixed without a note.

We never quietly change a claim to hide a mistake.

Recent corrections

Date	Guide	What changed
11 Sep 2026	Polar bear facts for kids	Correction. We said 45 kg of blubber weighs about as much as an average ten-year-old. An average ten-year-old weighs about 32 kg. 45 kg is closer to an average 13-year-old.
11 Sep 2026	Giraffe facts for kids	Correction. We said about 117,000 giraffes remain. That was the 2020 estimate. The 2025 count is about 140,700.
11 Sep 2026	Gorilla facts for kids	Correction. We said Fatou, at Berlin Zoo, passed Colo’s age in 2020. Colo died in 2017, so Fatou passed her age that year.
11 Sep 2026	How fast can an owl fly?	Correction. We said owls reach 40 mph when hunting. We could find no study that supports this. The guide now gives speeds that scientists have measured.
11 Sep 2026	Can polar bears survive in the desert?	Correction. A picture claimed polar bears overheat at 10°C. No source supports this, and a 2022 study found signs of heat stress above 20°C. We removed it, along with an AI-made picture of a polar bear in a desert.
11 Sep 2026	Stone Age people	Update. A 2025 study dated the mammoth-bone hut at Mezhyrich, Ukraine, to about 18,000 years ago, built from at least 37 mammoths. We had said 15,000 years and 95 mammoths.
