We argue that the narrow mentorship model based on the top-down “publish or perish” approach to success and impact facilitates processes that lead to a reduction in diversity and innovation (illustrated by the inverse gray pyramid) and a detrimental STEMM culture that supports a limited subset of scholars. By contrast, a multidimensional mentorship model supported by those in leadership roles (e.g., by university and college presidents, chancellors, and provosts) working across academic institutions will incorporate diverse measures of success and impact to create system-wide change (illustrated by the purple pyramid). We argue that the latter approach can lead to increased innovation that will transform STEMM culture where processes, which support the 2 models, and outcomes of each, are side highlighted within the oval shapes.
