Introduction
In a world overflowing with information, conflicting narratives, and relentless choices, our minds instinctively seek shortcuts—patterns, biases, and illusions that help us make sense of complexity but often lead us astray. These mental traps shape the way we assess risks, make investments, and even choose our life’s direction, often without us realizing their subtle influence.
This book unearths the most common biases that cloud our judgment, not as mere flaws to be corrected, but as invitations to deepen our awareness. By understanding these cognitive distortions, we can learn to navigate uncertainty with greater clarity, make more intentional decisions, and reclaim agency over our thinking in an age where distraction and deception are the norm.
