I was once admonished by a GP because during a consultation when I was going through a tough time and reached out for support, I explained the things that were bothering me, causing anxiety and starting to impact all aspects of my life, and was told rather disdainfully that "I think too much".
I was told last year, by a psychiatrist involved in the care of my batshit SM who had turned on my DF and myself for reasons partly mental health related, and likely partly organic, that "I wasn't a doctor, and therefore should wind my neck in" when questioning the proposed course of action. What I voiced, and feared, came to pass with tragic results for my DF. But I was apparently "paranoid" and voicing my concerns due to my own nefarious agenda.
Years ago, during a fraught situation, again while at odds with "authority" I was forced to submit to psychological examination for legal purposes. They couldn't find anything measurably wrong with me, but the third psychiatrist told me loftily that I should "humble myself" because who was I to question the consensus of experts - it was a groupthink situation, and while it felt very much like a conspiracy, it could be more described as a "preserving the status quo that has served us well till now" scenario.
Point is, the urge or need to control narrative and perception has many motivations, and is applied up and down the scale. Think of the scandals that have dominated the news in the last few years. Post Office. Definitely a conspiracy. Contaminated blood? My hobby horse - nuclear test veterans - my Dad was one.
The tactics of suppression are psychological. And I agree Edward Bernays is a good place to start to track how sophisticated, and yes, lucrative the field is.
The pandemic was fertile testing ground. The 77th brigade is a real thing. Everyone held in place, dependent on technology, being fed information from multiple sources, conflict over reliability, and as always I will hark back to the now demised "State of Fear" threads, which started as discussions of a book by the same name, and ended with fears of right wing extremism and civil unrest.
Currently the news is full of war rhetoric despite the ceasefire in the Middle East. Now we are encouraged to prepare for war on our own shores. This is scoffed at by some, embraced by others. If one dares suggest "they're up to something" well, that's conspiracy theory.
And the "nebulous they" - these days, anyone with a vested interest in steering public opinion and compliance, mostly driven by money, and access to digital tools. Which is why AI is such a threat.
It's not just a question of conspiracy theory versus actual conspiracy, it's reality versus complete fantasy, and eroding our ability to distinguish between the two. Our greatest weapon is our own mind, but it's also our greatest weakness.
By the way OP you might enjoy a YouTube channel called Truthstream media. They cover this sort of thing.
