The paper reviews and assesses the negative and positive advice which has been offered by various fellow economists to heterodox economists in general, and Post-Keynesian economists in particular, in light of changes that have occurred within neoclassical economics and in light of the rising hegemony of mainstream economics in economics departments. Various strategies are considered, among which is more engagement with orthodox dissenters, but it is concluded that the majority of heterodox economists ought instead to engage more with other heterodox economists and possibly other social sciences, developing and expanding their own agenda around real-world problems.
