If you are new to the idea of bias, there may be a lot in this book that surprises you. She does a good job capturing examples and writing about them in a conversational way that's easy to digest. If you've spent years seeking out studies, articles or papers on the topic, there's likely little that's new or novel here for you. Nutshell: it's well written and well organized – I think the star rating will depend on the audience and their existing knowledge base.
