Dickens' research interests include
unemployment,
race and intelligence, and changes in IQ over time (the
Flynn effect). For example, he co-authored a 2006 study with
James Flynn showing that the black-white IQ gap in the United States had decreased in size by at least 25% between 1972 and 2002. He and Flynn had previously proposed a hypothesis for why IQ appears to be both highly heritable and significantly affected by the environment. Their hypothesis argued that individual's IQs are significantly affected by both genes and environment, but that people's environments change in response to their IQs. Dickens has also worked with Nobel prize winner
George Akerlof. Together they authored the 1982 paper "The Economic Consequences of Cognitive Dissonance". Scholars have described the Akerlof–Dickens model of cognitive dissonance as an influential early template for integrating psychological mechanisms into formal economic theory. Akerlof and Dickens also wrote two papers on inflation and unemployment in which they argued that psychological considerations lead to a long-run
Phillips curve where there is a trade-off between inflation and unemployment. ==References==
