--- - |2 Abstract This special issue brings together seven contributions which, in spite of the diversity of the topics and theories being covered, all make use of Self‐Determination Theory (SDT) as their guiding, complementary, or contrasting framework. In this commentary we first reflect on how SDT has developed organically and conservatively from “within,” based on emerging patterns of evidence, as well through ongoing challenges from other models and frameworks. We then discuss each of the various contributions to this special issue, addressing themes that include SDT's breadth of methods, and its relevance to topics such as narcissism, wisdom, individual differences, big‐five traits, and the neuropsychology of motivation, among others. Across these discussions we highlight fruitful avenues for research and cross‐fertilization across the fields of personality, development, motivation, and neuroscience. At the same time, we counter some claims made about SDT, and forward certain cautions regarding the integration of SDT and other personality frameworks and models. We conclude by revisiting the value of broad theory for coordinating complex research findings across levels of analysis, and perhaps more importantly, for pointing us to the right questions.
