The discussion centers on the concept of "willful blindness," which refers to the tendency of individuals to ignore uncomfortable truths or information they should be aware of. This term, originally a legal concept, highlights how people often choose to remain uninformed about issues that present moral or cognitive challenges. The conversation also touches on the role of social media in facilitating this avoidance by creating echo chambers that allow individuals to engage only with agreeable perspectives, further entrenching their ignorance. The mention of Margaret Heffernan's book on the topic suggests a deeper exploration of how willful blindness operates in various contexts.
