T he Trust Algorithm uncovers the hidden mathematics behind human belief - revealing how credibility, authority, and identity are silently calculated in our minds and manipulated by modern systems. Blending insights from data science, social psychology, misinformation research, and algorithmic justice, the book argues that trust is not instinct but a system - one that has been corrupted by digital platforms, political exploitation, and structural bias. Through vivid storytelling and rigorous analysis, it explains why misinformation spreads faster than truth, why institutions struggle to regain credibility, and how algorithms have rewritten the rules of trust for profit. Yet it also offers a blueprint for repair: transparency, recalibration, and justice. This is not just a diagnosis of a broken system, but a manifesto for reclaiming belief in an age of manipulation. Provocative, timely, and deeply human, The Trust Algorithm challenges readers to see trust as both a currency and a code - one that can be hacked, but also one that can be rewritten. It is a call to action for anyone who cares about truth, democracy, and the future of shared reality
