Abstract
The proliferation of leadership models can leave practitioners confused about which model to use in guiding their leadership development initiatives. Although ‘new’ leadership models (e.g. authentic, ethical, and servant leadership) suggest theoretical differences, empirical research has shown considerable overlap among these models and longer standing ones such as transformational leadership. With extant literature questioning the added empirical value of these newer models, this paper aims to distil the best evidence about transformational leadership into a ‘primer’ that can help practitioners use evidence-led practices in their leadership development. To do so, we briefly review major leadership models, highlight evidence for empirical redundancy between new leadership models and transformational leadership, and discuss meta-analytic findings between transformational leadership and outcomes of leadership. Our review suggests that these newer leadership models add little incremental validity beyond transformational leadership in predicting various leadership outcomes. Moreover, transformational leadership demonstrates medium to large effect sizes on a range of individual, team, and organisational outcomes. Taken together, our findings suggest that organisations can benefit by focusing their resources on transformational leadership development, rather than on the latest leadership fad.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
