AlphaBetaMinds lists material corrections here: what was wrong, what it says now and when it changed. Typo fixes are not listed. Report an error through the contact page.
How corrections work
When a figure, a tool result or a statement on this site turns out to be wrong, we fix the page, change its update date and list the correction here. Spelling and layout fixes are not listed. To report an error, use the contact page and include the page address.

- Tool pages. About 690 tools without their own FAQ showed the same four answers, and one of them said every tool uses the McCrindle generation boundaries and UN population rates. That was not true of the psychology, money and slang tools. The shared answers are gone; each tool page now shows its own worked example and data.
- Calculator results. 30 calculators printed long unrounded numbers (for example 34.596000000000004), and the bedtime calculator showed times as decimal hours (20.67) instead of clock times (20:40). Both now display correctly.
- Dates. Seven data pages printed the current month as their update date whether or not the data had changed. They now show the date the data last changed.
- Data markup. Country pages described their data as covering the whole world and the years 2025 to 2040. They now name the country and the years the figures cover.

- School-year calculators. Ten school-year tools counted the school year from January instead of the month it starts. Answers for France, Japan, India, Pakistan, Nigeria and Australia were wrong for children born in some months and have been corrected.

- Daily posts. A fact-check of the first daily posts found a misattributed quote, an expert given the wrong name, a statistic that appeared in no source, outdated American Academy of Pediatrics guidance, wrong Roblox settings and a Microsoft feature that no longer exists. Every one was corrected against its source, and one post that said no health body sets an hourly screen limit for a seven-year-old now cites the Canadian and Australian two-hour guidance.
23 September 2026
- Generation boundaries. The boundaries were corrected to Pew Research Center's for the older generations and McCrindle's for Generation Alpha and Beta, and 43 places that credited a boundary to the wrong source were fixed.
- Philippines. The fertility rate for the Philippines was given as 2.7 children per woman; it has been corrected to 1.9.
