John Charles Simon and Jennalee Donian, "Understanding Laughter and Humor: Why We Laugh, Why We Don’t, and Why It Matters" (Palgrave MacMillan, 2026)

In John Charles Simon and Jennalee Donian’s Understanding Laughter and Humor: Why We Laugh, Why We Don’t, and Why It Matters (Palgrave Macmillan, 2025), the authors put forward a comprehensive new theoretical approach to understanding laughter and the humour we use to inspire it. Applying an evolutionary and biological lens to these complex and universal human behaviours, the book distinguishes itself from classical and contemporary theories by focusing not simply on laughter’s causes and effects, but on what can be gleaned from considering its communicative meaning.
