Falsity carries less information, less entropy and consequently travels more efficiently through a transmission medium.
Social media addiction is a growing phenomenon. It is a problem-space defined by the deep irony that the more connected we all become by the putatively "social" information and communication technologies, the more isolated we all feel ourselves to be. In this context, expectation is fundamentally, foundationally discontinuous with experience.
Ideological turbulence, media distrust, fake news and the hyper-inflating bias towards successfully self-propagating inflammatory rhetoric in (or as) social media is one instance of a broader principle through which life and intelligence negotiate and harness or exploit entropy in information and energy processing systems.
This contemporary information and communications technology environment provides a rich and fertile testbed for observing, borrowing and repurposing concepts and methods of influence and persuasion-for-effect.
