Perspectives on Post-Truth

‘Post-truth’ denotes a cluster of phenomena that pose significant epistemic and societal challenges, including the proliferation of confirmation bias, denial of scientific findings, reinforcement of beliefs within echo chambers, and rampant spread of misinformation, conspiracy theories, and fake news—most notably via social media platforms. These phenomena have tangible effects, manifesting in a societal schism and contributing to public opinion polarization. Trust in scientific institutions and expertise is eroding, and the fragmentation of public opinion in opposed ‘epistemic tribes’ threatens the very foundations of democratic societies, undermining the role of scientific bodies in public discourse and policy-making. Drawing on diverse methodologies, theoretical frameworks, and expert insights, the contributions to this book scrutinize core post-truth phenomena through a multi-disciplinary lens and construct a nuanced understanding and an effective toolkit to confront the challenges posed to our social fabric.
