This book offers a behavioral science perspective on how scientific practice becomes compromised and provides recommendations for improvement. Broadening the discussion of research integrity beyond replication, publication biases, statistics, and methods, this book addresses the full complexity of the issue and serves academics and policy makers concerned with the reliability and validity of scientific findings across the social sciences. It tackles challenges presented by published reports and textbooks, addresses the ways that institutional review boards (IRBs) can influence the course of research, and discusses the weaknesses of meta-analysis, which is often recommended as a possible corrective measure for suboptimal scientific practice. The book concludes with an organizing framework to investigate how scientists' behaviors can impact the reliability and validity of scientific research.
