Garfield/Seglen's warning against journal-mean-citation-as-individual-proxy and Steck/Ekanadham/Kallus's warning against cosine-similarity-as-relatedness-proxy share the identical structure: a cheap scalar misapplied as a substitute for a harder judgment

claim seedling Tier 1 2026-08-31 · garfield, seglen, harald-steck, cosine-similarity, impact-factor
Does the measurement-theory or statistics literature already name the general pattern behind the Garfield/Seglen and Steck/Ekanadham/Kallus warnings — a scalar aggregate substituted for a property it cannot measure?

Halley's 1693 Breslau paper produced the first life table built on population data and founded the pricing of annuities on lives

Edmond Halley founded both transit-of-Venus parallax and actuarial annuity pricing, and each method was adopted only after his 1742 death

The bridge between the exoplanet-parallax note and the Dodson note is real: Edmond Halley is the shared ancestor of both — same polymath, two founding measurement methods, both vindicated after his death

Halley's 1716 method derives the Sun's distance from transit-of-Venus timing differences observed with only telescopes and common clocks
