The Counterspeech Trias Taxonomy: Behavioral, Affective, and Cognitive Techniques Synthesized from a Systematic Literature Review

This paper presents the Counterspeech Trias Taxonomy, a comprehensive classification of counterspeech techniques against hate speech and other forms of incivility in social media.The taxonomy categorizes counterspeech techniques into three primary psychological-functional domains, paralleling the behavioral, affective, and cognitive components of attitudes and persuasion: (1) Behavioral techniques appeal to social norms and evaluate behavior, (2) affective techniques influence through emotional engagement, and (3) cognitive techniques aim to change beliefs or understanding through information and reasoning.The techniques were identified through a systematic literature review of English and German sources published between 2004 and June 2025, describing specific intervention techniques against hate speech and other forms of incivility. Through an iterative and inductive empirical-to-conceptual approach, 16 distinct techniques were identified and organized into seven strategies within the three overarching approaches.An initial search conducted in March 2024 established the tripartite structure based on 43 sources. Two subsequent updates (November 2024 and June 2025) added 11 additional sources, resulting in a final sample of 54 articles.The Counterspeech Trias Taxonomy clarifies the concept of counterspeech by detailing its elemental techniques, enabling a precise definition and facilitating systematic investigations into the effectiveness of different techniques. By providing a psychologically grounded framework, the taxonomy supports systematic investigation of counterspeech effectiveness and the development of evidence-based interventions to foster constructive online discourse and democratic participation. Furthermore, it offers a practical basis for educating community managers and citizen counter-speakers.
