This note introduces an eight-league framework for differentiating think-tanks based on the volume and regularity of their research output. The framework categorises think-tanks into eight distinct leagues, ranging from leading institutions (L1) to non-existent entities (L8), offering a simple method for classification. The focus is on written publications as the primary criterion for this differentiation, though other criteria could be considered. Examples include temporary think-tanks formed through EU-funded research programs and organisations with minimal or no active output. This framework aims to provide a theoretical structure for understanding the varying calibres of think-tanks.

It contributes to the literature by offering a clear and structured framework for categorising think-tanks based on their research output, providing a simple tool for differentiating their calibre. It fills a gap by introducing an eight-league model that can help classify think-tanks, especially those with limited or temporary activity, in a way that hasn’t been explicitly addressed before.
