Compton's New Handbook Takes Stock of Inoculation Theory's Past, Present, and Future
A new volume published by Wiley brings together leading scholars to explore one of the most influential—and still evolving—theories of persuasion and resistance.
The Handbook of Inoculation Theory and Practice, edited by Bobi Ivanov (University of Florida), Kimberly Parker (University of Kentucky), and Josh Compton (Dartmouth College), is the first handbook devoted entirely to inoculation theory. The book includes contributions from 45 scholars across more than 30 chapters, covering topics such as health communication, political messaging, education, media, and emerging technologies like generative artificial intelligence.
Inoculation theory, first developed in the 1960s, explains how exposure to weakened forms of persuasive arguments can help people recognize and resist stronger attempts later. Over time, the theory has expanded far beyond its original settings, finding use in areas like public health campaigns, crisis communication, conspiracy research, and digital media.
Instead of presenting inoculation as a fixed or final framework, the handbook treats it as a dynamic theory—one that continues to be tested, refined, and challenged as persuasive environments change.
"This project started with a fairly simple question," said Compton, Professor of Speech at Dartmouth College. "What does inoculation theory look like now, after decades of work across very different domains? The answer, we found, is that the theory has a strong core—but it's still evolving in important and sometimes surprising ways."
Throughout the volume, contributors revisit foundational concepts while also exploring newer applications and directions. Several chapters focus on long-standing theoretical questions, including the mechanisms behind resistance to persuasion, the durability of inoculation effects over time, and the conditions under which those effects generalize—or fail to generalize—across issues and contexts. Other chapters expand the theory into new areas, such as therapeutic applications, social diffusion processes, and persuasive environments shaped by new technologies.
"Taken together, the chapters present a theory that is consistent yet flexible," Compton said.
The editors describe the volume as both a reflection and a guide for future research and practice. By incorporating a wide range of perspectives, the handbook seeks to clarify what defines inoculation theory while also emphasizing productive disagreements and open questions.
"Editing this book was a chance to pause and take stock of a theory I've been studying for 25+ years," Compton noted. "There's a lot of thoughtful, careful work out there. Bringing it all together in one place made clear not only how far the theory has come, but how much work still remains. There's still so much more I want to know."
