This book examines the psychology behind micro-targeted tactics used in election campaigning and the advent of increasingly sophisticated dynamic Agent-Based Models (ABMs). It discusses individual profiling, how data and modelling are deployed to enhance the effectiveness of persuasion and mobilization efforts in campaigns, and the potential limitations of these approaches. Madsen particularly explores how psychological insight and personal data are used to generate individualised models of voters and how these in turn are applied to optimise persuasion strategies tailored to a specific person. 

Finally, the book considers the broader democratic dilemmas raised by the introduction of these tactics into politics and the critical civic importance of understanding how these campaigns function.This timely work offers fresh insights for students and scholars of political psychology, philosophy, political marketing, media, and communications.
