WHY EVERYONE THINKS THEY'RE RIGHT

Why Everyone Thinks They're Right: The Hidden Logic of the Human Mind

Derek Williams lost $340,000 on a Tuesday. Not through recklessness or ignorance - he had an MBA from Wharton and understood portfolio theory better than most. He lost it because his brain had learned the wrong lesson from the right experience, and that lesson had been running his decisions for twenty years without him knowing it.
His brain wasn't broken. It was doing exactly what every human brain does.
In Why Everyone Thinks They're Right, Carlo Thompson reveals the hidden architecture behind human disagreement, decision-making, and behavior. Drawing on three decades of neuroscience, cognitive psychology, and clinical research, Thompson makes the case that most of what we call irrational behavior is actually perfectly rational - once you understand the brain that's producing it.
Every human brain constructs its own version of reality. Not a different opinion about reality - a genuinely different construction of what is true, what is dangerous, what is worth wanting, and what is possible. Those constructions are shaped by genetics we didn't choose, experiences we didn't control, memories that have been edited without our knowledge, and neural templates laid down by the most emotionally significant moments of our lives. The result is that the person sitting across from you - your spouse, your coworker, your teenager - is not being irrational when they see things differently than you do. They are being completely rational inside a different constructed reality.
That insight, Thompson argues, changes everything about how we understand conflict, empathy, and change.
But the book doesn't stop at understanding. It holds a crucial tension that most discussions of human behavior avoid: recognizing the logic of a pattern doesn't mean the pattern should continue. Some cognitive differences are genuinely valuable - the anxious brain that spots risks others miss, the ADHD brain that hyperfocuses on exactly the right problem, the trauma-informed mind that reads power dynamics with precision. Others cause persistent suffering that insight alone cannot reach. Knowing the difference - and knowing what to do about it - is what the second half of this book is built for.
Through the stories of Derek, Nicole, Alicia, Kevin, Sophia, Jordan, and five colleagues in one meeting room who walk away convinced everyone else was being unreasonable, Thompson builds a framework that is at once scientifically grounded and radically human. Readers will come away understanding not just why people think the way they do - but how to work with that reality rather than fight it, and when to seek the kind of help that understanding alone cannot provide.
Why Everyone Thinks They're Right is for anyone who has ever been baffled by someone they love, frustrated by someone they work with, or trapped by a pattern they can see clearly but cannot seem to change. Which is to say, it is for everyone.
