Quick answers
Does this atlas rank groups by IQ, race or nation?
No. Pathways and evidence stay individual. Scores are browsing aids — never group biological or racial ranks.
What did SMPY change?
Above-level SAT at 12–13 revealed residual differences among the already high, and later adult outcomes in STEM.
Are olympiad medals a gift assay?
They measure contest craft under a syllabus. Coaching density (China, Korea, Russia физмат) is already in the score.
Did Ramanujan prove genes are everything?
He also had the Cambridge correspondence and a tradition of temple-school calculation. A jagged profile, not a racial parable.
Is fast arithmetic the talent?
It is one visible skill. Proof, modelling and spatial insight can be quiet in timed tests.
Do girls “lack” maths talent?
This page will not run that folk story. Participation, stereotype and coaching explain much of historic gaps; we do not rank sexes as essences.
Practice means designed work with feedback — Ericsson’s construct, not Gladwell’s hour ticket.
Where Macnamara et al. 2014 published domain bands (games ~26%, music ~21%, sports ~18%, education ~4%), this page uses those rounded figures and does not invent new precision.
Steps
- Give a harder page
Above grade, untimed first.
Ceiling check.
- Ask for a reason
One written why.
Proof seed.
- Offer a hint ladder
Dynamic assessment.
Zone.
- Log designed practice
Weak problem types, not only mocks.
Ericsson, modestly.
- Find a circle
Club or camp.
Peers.
- Name the flavour
Contest ≠ research.
Honesty.
Checklist
- Ceiling lifted — Grade test may be maxed.
- Reasons written — Not only ticks.
- Coaching named — Hours are a variable.
- No group rank — IMO is not anthropology.
- Girls not written out — No essence story.
- Mentor exists — Gagné catalyst.
- Load checked — Camp ethics.
- ~4% humility for homework — Macnamara education band.
Drills
- Two-speed set — Same idea, then a proof version.
- Hint-then-retry — Dynamic mini-test.
- Explain to a younger student — Teaching as check.
- Contest then open problem — Switch flavours.
- Error journal — Which structure was missed.
Pitfalls
- Speed as destiny — Hides proof minds.
- National league tables as genes — Systems, not essences.
- 10,000-hour posters in algebra — Wrong Macnamara band.
- Harvesting contest children — Medals without a life.
Tools
- Above-level past papers — Honest ceiling.
- A proof notebook — Reasons dated.
- Art of Problem Solving-type communities — Peers, with adult watch.
- SMPY/CTY information in more languages — Access.
Mathematical talent: design the hour; retire the poster. Education is not a diagnosis.
