Eddie discussion in The Leftish Agenda centers around the concept of the 'big lie', a psychological manipulation technique in which a massive falsehood, when told convincingly and often enough, may pass as a truth to many. The episode began by tracing its sinister beginnings back to Adolf Hitler in 'Mein Kampf' and its subsequent weaponization in totalitarian regimes to distract the public and secure control. Eddie then looks at how modern applications in U.S. election fraud claims and public health misinformation persistently shape discourse, stressing social media's role in echoing these lies further. The episode also covers the psychological mechanisms, such as cognitive dissonance, confirmation bias, and reliance on authority figures, contributing to the technique's effectiveness. Eddie emphasized the need for critical thinking and media literacy to counteract the 'big lie.'
