Avram Hiller

Avram Hiller is the author of a 2023 comment in the journal Intelligence (volume 97, article 101732) on Gignac and Zajenkowski's 2020 test of the Dunning-Kruger effect. The comment argues that the 2020 paper's equal-error result probably comes from how a comparative self-rating of intelligence was converted onto a linear scale. Gignac and Zajenkowski published a reply in the same volume.

Who they are

The comment lists his affiliation as the Department of Philosophy, Portland State University, Oregon. Nothing else about his career was checked for this page.

The comment's argument, as recorded in the vault, is about measurement. It cautions against treating ordinal ratings as if they were interval data. The abstract itself could not be retrieved for this page, so the summary rests on the Crossref and PhilArchive records.

Key ideas

The comment is a view about scaling: if a self-rating is ordinal, treating it as a linear scale can produce a result that looks like equal error across ability levels. In their reply, Gignac and Zajenkowski report re-running the analysis with the transformation Hiller suggested and again finding no support for the effect. The two papers are opposing views about the analysis, and this page does not judge between them.
