Conversations in <i>Evaluation</i> – Exploring 30 years of debates in our field

Based on an original bibliometric analysis, this article examines three decades of Evaluation’s publications, mapping the key conversations and debates that have shaped the journal. Using a network analysis of cross-citations and a systematic review of the journal’s authorship, we identify eight clusters of closely interconnected articles that represent central thematic areas: ‘evaluative complexity’, ‘theory-based evaluation’, ‘realist evaluation’, ‘dialogue in evaluation’, ‘evaluation use’, ‘evaluation systems’, ‘politics of evaluation’ and ‘accountability’. We detail the content of each cluster, highlighting key authors and specific subtopics, and trace the intellectual exchanges both within and across these thematic boundaries. Our findings reveal a broad conceptual shift over time, in which early emphasis on evaluation use and dialogue has given way to growing interest in evaluation systems and capacity, theory-based approaches and complexity. In sum, we offer a cross-cutting perspective on some of the evolving debates that have shaped the European evaluation community over the long term.
