Decisions are influenced by a variety of fallacies and biases that we can learn how to avoid. Critical thinking values, knowledge, and skills, therefore, are integral to evidence-based practice. These emphasize the importance of recognizing ignorance as well as knowledge and the vital role of criticism in discovering how to make better decisions. This book is for clinicians--clinicians who are willing to say "I don't know." Critical Thinking in Clinical Practice, Second Edition is designed to enhance readers' skills in making well-informed, ethical decisions. Making such decisions is no easy task. Decisions are made in uncertain, changing environments with time pressures. Interested parties, such as the pharmaceutical industry, spend millions of dollars to influence decisions made. Drawing on a wide range of related literature, this book describes common pitfalls in clinical reasoning as well as strategies for avoiding them--sometimes called mind-tools. Mental health and allied professionals will come away from this text with knowledge of how classification decisions, a focus on pathology, and reliance on popularity can cause errors.
