Hannah Arendt's "defactualization" is a concept that describes the erosion of truth and the rise of relativism in society. She argued that this was a dangerous trend, as it made it difficult to have meaningful conversations about important issues. Post-truth is a term that has become increasingly popular in recent years. It refers to a situation in which emotions and beliefs are given more weight than facts in shaping public opinion. These two concepts are closely related, but they are not the same thing. Defactualization is a broader concept that encompasses the rise of relativism and the decline of trust in institutions. Post-truth is a more specific concept that refers to the use of emotions and beliefs to shape public opinion. It is important to note that post-truth does not rely on absolute lies. In fact, post-truth often relies on half-truths and misinformation. Post-truth actors may also use facts, but they will often use them in a misleading way.
