© 2018 Inderscience Enterprises Ltd.In this article, we explain why economics has not become an evolutionary science since Veblen published his seminal 1898 paper, 'Why is economics not an evolutionary science?' One cause of economists' reluctance to displace non-evolutionary preconceptions in economics is that the history of economics in the second half of the 20th century has been characterised by conceptual schizophrenia, defined as a state where economists do not change their minds although critical scientists provide abundant counter-arguments and refuting evidence. The (evolutionary) 'drift' that Veblen thought would transform economics into an evolutionary science has become an evolutionary process itself. We argue that an alternative path for the heterodoxy, akin to speciation in biology, is needed.
