"The Fortress of Belief – Why facts make us fight harder for our lies" explores the "Backfire Effect." We assume that if we show someone facts that disprove their belief, they will change their mind. Neuroscience shows the opposite: When our core beliefs are challenged, the amygdala (fear center) activates as if we are being physically attacked. We double down on the lie to protect our identity. Psychologist Rachel Wall explains why debunking myths often spreads them and why political arguments on social media are futile. The book provides strategies for "bypass persuasion"—how to frame information so it doesn't trigger the brain's defense mechanisms. "The Fortress of Belief" is a guide to navigating a post-truth world. It teaches readers that you cannot win an argument with logic alone when the other person is fighting a battle for their psychological survival.
