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.
Is it just high g?
Cognitive starting points help. Time, patrons, and not being forced into one guild help more. Many high-IQ lives are narrow.
Did Leonardo invent the type?
He is the brand. Ibn Sina and others already lived multi-domain scholarly lives.
Can you train polymathy?
You can train a second domain (see late-bloomers). Whether the world allows two recognitions is a labour-market problem.
Is T-shaped the same?
T-shaped (depth plus a little breadth) is a workplace slogan. Polymathy is two or more depths. Do not flatten.
Are prodigies polymaths?
Rarely. Prodigies are usually domain-specific (Winner). A second domain may arrive later.
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.
