This book represents a carefully curated set of contributions that aim to inspire the current and next generation of researchers – and to encourage how the act of challenging current conceptual boundaries is needed to advance science. Social-behavioral modeling will continue to be beset by uncertainties because the social-behavioral phenomena occur in complex adaptive systems into which we have imperfect and sometimes contradictory insight. Nonetheless, such modeling – if undertaken appropriately – can help humans who must plan, operate, and adapt in their complex worlds. One of the editors themes is most welcome: complexity need not be paralyzing, especially if we take a multidisciplinary use-centric approach to working on real-world problems.All in all, this volume is a welcome contribution that will be valuable to diverse audiences in schoolhouses, research laboratories, and the workplace. It is a collection, not a textbook or single-author monograph, and it conveys an excellent sense of the current state of the art and the exciting opportunities that are nowbeing exploited.The editors deserve credit for bringing about, organizing, and personally contributing heavily to this volume that merits a prominent place in the libraries of human behavior researchers, as well as those interested in helping solve some of the larger socio-technical issues facing us.
