Informal IQ estimate

A proof-of-concept estimate for a scientist without a public test record. The badge says Estimate because this is not a measured IQ.

Informal estimate, not a verified public IQ score.
Method and limits

Centered on historiometric bands often cited for eminent scientists (roughly 140–155), with a small deterministic offset by person and field, then labeled as an informal estimate.

  • No primary test report supports this number.
  • Achievement, occupation, and prizes are not IQ tests.
  • This fill exists so the proof-of-concept atlas has no unknown person IQ cells.

Uncertainty: Typical bands for eminent scientists are wide. A Nobel Prize or discovery does not identify a test score.
