Post-Truth

Post-truth is the political subordination of reality. It is not a failing of knowledge, but one of politics. Authoritarians use post-truth to corrupt our faith in the truth. The end goal is not to make citizens believe lies, but to make them so cynical and uncertain, they think they can never know the truth. Once this control over the information stream is achieved, leaders begin to have direct control over the populace. Post-truth marks the beginning of the descent into fascism for this reason.

Fake News

Fake news is intentionally false news. It's a key tool in the pursuit of post-truth because it muddies the waters of reality. Once misinformation is in the public sphere, it is impossible to remove. The more fake news saturates the information market, the more jaded the target population becomes. Authoritarians can further confuse people by labeling the truth as fake news; they deny facts and demonstrate their control over their country's information stream.

Propaganda

Propaganda is the most potent weapon in a post-truth leader's arsenal. It is not designed to simply fool a population. Instead, it exists to demonstrate the government's command of truth and that the truth is subordinate to the will of the leader. It shows the government's ability to lie with impunity. Even if the population doesn't believe the lie, it overwhelms their defenses, making them easier to rule.
