In Decision Design, entrepreneur and clinical researcher Tasher Adaarewa shows some of how the mind works as he gets down to the business of decision making. Based on the author's synthesis of wide reading and research, he boils down designing decisions into three parts sprinkled throughout the book: the environment in which you make and test decisions, how to think about your choices, and building confidence in the decisions you make. Decision Design blends contemporary business stories and research from behavioural economics, behaviour change, leadership, and emotional intelligence. From these, each chapter follows the life of Abraham, highlighting specific action steps for setting a personal vision, building rich, enduring relationships and walking with God as the patriarch did. Drawing on wisdom from the Bible, the author urges readers to focus on the calling for which God has uniquely equipped and qualified them. Through these lenses of scripture, science and business, the book offers insights into how we make choices in our business and personal lives and guard against the mental tendencies and shortcuts that can get us into trouble.
