Footnotes

Editor's Note: On September 4, 1936, L. L. Thurstone gave the presidential address at the first annual meeting of the Psychometric Society in Hanover, NH. Uncertainties about the viability of the new journal, Psychometrika, led his colleagues to urge him to publish his address in Science. Excerpts from that paper are reprinted here. Thurstone's examples are now quite dated, and have been omitted, thus thwarting his major intent of providing examples of quantification. But his point of view towards the goals of the new Society is remarkably fresh, and is expressed with typical Thurstone clarity. The reference to the complete paper is:
