# Tests of Hereditary Intelligence **Status: stub.** Article 5 of six in [[Lippmann Intelligence Testing Series]], published in *The New Republic* on 22 November 1922. The direct assault on the hereditarian inference. [[Walter Lippmann]] grants for argument's sake that the tests measure *something* consistently, then asks what licenses the leap from that something to inborn, heritable capacity. His answer is: nothing in the data. Environment, schooling, language, nutrition, and early childhood development are entangled with whatever native endowment exists, and the testers had performed no operation capable of separating them — while systematically ignoring the developmental years in which the entanglement is formed. He closes with the epistemological verdict that gives the series its lasting force: the hereditarian reading rested on "a will to believe, not the methods of science." The conclusion had preceded the evidence. That is the standing charge against [[Scientific Racism]] in every subsequent generation. *Stub — expand with: the full text argument in sequence, verbatim passages, and the specific psychometric claims rebutted.* See also: [[Lippmann Intelligence Testing Series]], [[Walter Lippmann]], [[Eugenics]].
