Ronald K. Hoeflin (born February 23, 1944)[1] is an American librarian by profession, philosopher and amateur psychometrician.
Hoeflin stated in an interview that his goal was "to make a living publishing journals for high-IQ societies."
[8] In 1987 he earned a doctor of philosophy (PhD) from the New School for Social Research, the graduate division of The New School, with a thesis titled "The Root-metaphor theory: A critical appraisal of Stephen C. Pepper's theory of metaphysics through an analysis of its interpretation of the concepts of truth, beauty, and goodness.
[11] For over a decade, he worked on a thirteen-volume treatise titled "The Encyclopedia of Categories", which was published in 2020 online and is available to download for free.
Hoeflin standardized the test six times, using equipercentile equating with SAT and other scores, and some extrapolation at the highest level.
Attempts to eke out discrimination at the hundredth or thousandth percentile were clearly overwhelmed by the test's standard error, given that there were only 48 questions.
