Over the years, the General Theory has been as controversial as it has been influential. However, many of the controversies have been fanned by misunderstandings of the General Theory. In addition, resolution to the controversies were sometimes delayed because the models used to account for specific phenomena were not yet developed. This chapter addresses these controversies by showing how specific empirical phenomena once thought by some to challenge the General Theory are actually predicted a priori by retrieving effectively from memory (REM) models originally designed to account for forgetting.
