Despite three decades of research and development of anti-bullying intervention, this form of systematic aggression continues to be common in schools. The present study investigated if a contributing factor might be that some pupils are unreceptive to teachers' anti-bullying lessons. It invited 8-11-year-old junior school pupils (N = 227) to indicate if this was the case, and if so, to give their reasons. Many did indicate being unreceptive (81.9%). The most common reason was "It is not for me because I don't bully anyone" (81.9%), followed by "I know enough about bullying already" (22.9%), "It is boring or I have heard it all before" (19.4%) and "Teachers have to do it but they are not really interested in stopping bullying" (14.5%). Some significant age differences emerged. Results are discussed in terms of implications for anti-bullying work in schools. (Contains 1 table.)
