Open Letter – Letter of Protest

<div>Last year, Earl Hunt published an article on international differences in intelligence in Perspectives on Psychological Science. Hunt’s article reviewed the causes and consequences of international differences in cognitive ability, problems measuring international differences in cognitive ability, and the relevance of such differences to modern society. Robert Sternberg (2013) provided a commentary on Hunt’s (2012) article, and Sternberg‘s commentary is the focus of our letter.</div>
