Truth Addict: How to Ask Questions, Test Ideas, and Get Answers in a Data-Driven World

Foreword by Charles Wheelan, author of New York Times bestseller Naked Statistics: Stripping the Dread from the Data What makes some evidence strong, some evidence weak, and some evidence total nonsense? Truth Addict is your guide to answers. Individuals, policymakers, and businesses across the globe want to make decisions based on evidence. But not all evidence is created equal. Truth Addict is the layperson's guide to data, truth, and the gap between them. Whether it's collected through laboratory experiments or public surveys, market research or archival records, data has a story to tell us―but only if we can read it. Drawing on engaging examples, John V. Kane details the logic of gathering and analyzing data as a means of getting us closer to the truth, even if the truth hurts. Developing research questions. Defining variables. Choosing metrics. Testing hypotheses. Quantifying relationships. Ruling out chance. Considering alternative explanations. Knowing not just that "correlation does not equal causation," but also how to tell the difference. These are key steps along Kane's "Road to Evidence," a journey that begins with curiosity and ends at objective knowledge. You don't have to be a math whiz to study our social world―Truth Addict provides every reader tools to uncover the reality within the numbers.
