The Seven Deadly Sins of Psychology

The Seven Deadly Sins of Psychology examines fundamental problems within psychological science and research practices. The book identifies seven core issues that undermine the field's credibility and scientific progress. Chris Chambers draws from his experience as a researcher and journal editor to analyze how these "sins" manifest in academic psychology. He presents evidence of publication bias, poor methodology, data manipulation, and other systemic failures across the discipline. The book outlines potential solutions and reforms to address each of the seven problems, including changes to funding, peer review, and research methods. Chambers documents existing reform efforts and proposes new approaches to make psychological science more reliable. This work serves as both a critique and a call to action for transforming psychological research into a more rigorous scientific enterprise. The analysis connects to broader questions about how science should be conducted and validated in the modern era.

🔍 Author Chris Chambers coined the term "scientific reformer," describing researchers who actively work to improve scientific practices while continuing their regular research 📚 The book identifies seven principal problems in psychological science: publication bias, hidden flexibility in data analysis, lack of direct replication, reliance on hypothesizing after results are known (HARKing), lack of data sharing, failure to consider statistical power, and journal obsession 🎓 Chris Chambers is a Professor of Cognitive Neuroscience at Cardiff University and pioneered the concept of "Registered Reports" - a publishing format that helps prevent publication bias ⚡ The book's publication in 2017 coincided with psychology's "replication crisis," when researchers found that many famous psychological studies couldn't be reproduced 🔬 The solutions proposed in the book have influenced research practices beyond psychology, spreading to fields like neuroscience, medicine, and biology
