Ian Deary and Robert Sternberg have been writing about intelligence differences since 1982 and 1977, respectively. As Deary was retiring at the end of 2020, they discussed an idea for their first joint paper. They composed five questions related to research on intelligence differences, about: attempts to find cognitive components of intelligence; the place of theory in intelligence research; the breadth of the concept of intelligence; hard problems in intelligence; and the use of cognitive tests in the real world. They answered them separately and then responded to the other's answers.
