There is considerable discussion on the so-called “mainstream pluralism”, which stems from the growth and coexistence of new research programs in economics that significantly deviate from the neoclassical core. Other disciplines have actively contributed to the birth of such programs, that are carried on by different, often separated communities of researchers. Although “mainstream pluralism” is not the pluralism heterodox economists and students groups have sought for in the recent decades, its persistence over time might provide a possible precondition for the advent of pluralism in economics. While the literature tends to regard mainstream pluralism as a transitory state towards a new, post-neoclassical, mainstream, this paper contributes to the debate by bringing in a different perspective, focusing on economics’ fragmentation and the necessity of specialization. We adopt a “late Kuhnian” framework (derived from Kuhn’s late works on specialization), considering not scientific revolutions but specialization as key engine of progress in science, and interpret mainstream pluralism as the result of economics’ recent growth in size and dive rsity. To account for the necessity of specialization in economics, we employ Ronald Heiner’s work on the competence-difficulty gap, as well as the evidence offered in some recent studies about the impact of the “burden” of previously accumulated knowledge on innovative behaviour. After a bird’s eye view on the recent history of economics in relation to other disciplines (and an analysis of Herbert Gintis’s “unity of behavioral sciences” proposal as possible new mains tream), we discuss the possibility that today’s “mainstream pluralism” might persist over time.
