An MBA is not enough. While there are a number of business schools that recognize the importance of critical thinking, few, if any, offer a specific course in critical thinking. Faculty members are experts in their respective fields: accounting, finance, management, marketing, sales, etc. But critical thinking, although interdisciplinary, is not specifically a business skill. Yet, successful business people do use critical thinking. In this book, Bob Schoenberg, a recognized teacher and consultant on critical thinking skills, outlines key tools and attitudes to help think more effectively about common business issues. From assumptions to frames of reference to ethics, critical thinking is the key to more effective business decisions. The revised and expanded second edition has added exercisess and a new chapter on critical thinking and social media.
