Best Quotes from the Book:
- “When people hold a strong belief that is central to their sense of self, they are more likely to go to great lengths to justify and rationalize their actions, even in the face of overwhelming evidence to the contrary.”
Analysis: This quote encapsulates one of the central themes of the book – the idea that our self-identity is deeply intertwined with our beliefs, making it incredibly difficult to admit when we are wrong. It emphasizes the lengths to which we will go to protect our self-image, even when it means ignoring undeniable facts. The lesson here is to be vigilant about the beliefs we hold dearly and be open to revising them when confronted with contrary evidence.
- “The more people commit themselves to a belief or course of action, the more likely they are to stick with it, even when it’s clear that they should change course.”
Analysis: This quote highlights the sunk cost fallacy, where individuals feel compelled to continue down a path they’ve invested heavily in, even when it’s evident that it’s a dead end. It serves as a reminder of the importance of recognizing when our investments, whether they be financial or emotional, are leading us astray, and the need to cut our losses and change direction when necessary.
- “In disputes, it’s often more important to save face than to discover the truth.”
Analysis: This quote underscores the destructive nature of our need to save face in conflicts. It can prevent us from finding common ground and resolving issues, ultimately perpetuating misunderstandings and feuds. It teaches us the value of humility, the willingness to admit when we are wrong, and the importance of pursuing truth and reconciliation over personal pride.

Book Review
Tavris and Aronson’s writing style is engaging and accessible, making complex psychological concepts understandable to the layperson. They use a plethora of real-world examples, ranging from political scandals to personal relationships, to illustrate their points, making the book relatable and thought-provoking.
One of the book’s strengths lies in its relatability. Most readers will find themselves nodding in recognition as they recognize their own tendencies to justify their actions or beliefs. It offers a sense of validation, reassuring readers that these behaviors are not unique to them but rather part of the human condition.
However, no book is without its flaws. Some readers may find that “Mistakes Were Made” occasionally delves too deeply into case studies and real-life examples, which can make it feel repetitive at times. Additionally, while the book does an excellent job of highlighting the problems with self-justification, it could provide more practical guidance on how to overcome these ingrained tendencies.
