IT'S ALL BS

It’s All BS dives deep into how biases shape our perceptions, decisions, and interactions. Drawing from psychology, behavioral economics, and personal experience, Mark Shub reveals how subconscious mental shortcuts control our thinking. With a blend of research and storytelling, he challenges readers to recognize their biases, question assumptions, and make clearer, more intentional choices. This book isn’t about eliminating bias—it’s about understanding it, breaking its grip, and taking control of how we think, live, and engage with the world.
