We are now at the point in our political degeneration where words are literally being redefined in an attempt to manipulate the perception of reality itself.
This is quite true. I think another relevant factor here is speed. The world nowadays seems to move so much faster than it did even a few years ago. It is partly 24-hour new culture, and partly everyone competing for attention on the internet, with everyone desperate to be first to report the latest developments. Each 'fact' is a headline only for a brief moment, before it is rapidly submerged by the next. If we combine this with the rise of social media and its facilitation of alternative methods of information dissemination, informal and unverified, without the responsibilities traditionally incumbent on print media and TV channels, then we reach a situation where people are bombarded with facts and 'facts', interlaced with misinformation, denuded of context, or just outright lies.
This is entirely intentional. People are inundated with conflicting 'truths', and these truths aren't open to careful analysis to determine what is accurate and what is not, because the sheer pace of news means that there is limited opportunity to evaluate what is truly happening before the next story is upon us. And once people become intellectually cast adrift like this, it becomes easier to erode their beliefs and to manipulate their behaviours. We can take Trump as a prime example here - lies after lies, each outrage quickly replaced by the next. It is the pace with which this all gets refreshed that prevents any in-depth study, and the pervasive climate of uncertainty that underpins it all provides a frictionless surface upon which all of this 'old' news can just slide away and be forgotten...
“We live in a world where the powerful deceive us. We know they lie, they know we know they lie, they don’t care. We say we care, but we do nothing. And nothing ever changes. It’s normal. Welcome to the post-truth world.”
