You see conspiratorial thinking as some kind of bug in the thinking of insuffciently skeptical and analytical minds; a branch of stupidity. But it's not. It's a self-defense mechanism which, like other things considered antiquated and ineffcient like borders and control over immigration saves people from mass death.
These things don't exist because people are stupid and can't reason. They exist because people aren't stupid and do reason and then believe in their own mind's creations.
No matter how smart or sophisticated or computer-aided your reasoning is, no matter how big your data set becomes, you will only match and elucidate upon, but not beat, instincts which evolved under real Darwinian pressures which make you aware and wary of things which kill en masse.
"Technically" in which sense? Which political science course taught you that? Or are you referring to some specific government?
That describes most plans people have.
So the planners deceive and dissemble. That is how the world has always worked.
What's more, it's instinctive knowledge that this is happening all the time. Suspicion of those in power is a human instinct which, like all instincts, optimizes our survival chances under the conditions for which it evolved. WRT to political conspiracies, those conditions still hold today.
The way to think about conspiracy theories is the same way you think about inventors and inventions.
Nature produces inventors (conspiracy minded individuals) many of whom produce only harebrained inventions ("conspiracy theories" so called) some more who produce hit and miss inventions and a few which produce inventions which are overwhelming important and matter to survival ("Hitler is going to kills us all, we must flee right now!" - spoken by a Jew in 1933 Munich).
What this mapping between domains, inventions and conspiracies, also implies is that just because someone was wrong about one conspiracy doesn't mean they are wrong about all conspiracies and their credibility should not be automatically bankrupted if they believe one or two false conspiracy theories.
I do read some conspiracy theory sites and like to hear plausible (non-alien/ lizard people) ones because I want my mind to at least entertain the idea. It's like panning for gold. Most of it is nothing. Once in a while, maybe a little taste of something and I retain it dimly awaiting future possible supporting evidence.
For example, the "desperate labor shortage" and "Americans don't like STEM" meme is a clear conspiracy amongst employers and attorneys and their clients to control engineering wages and have more of the profits go to business owners. I used to not know about that "conspiracy theory" then I heard it and wondered if it could be true then over time the evidence for it became incontravertible.
Just to give one example.
But the older I get, and the more understanding I have over how large organizations are ran, the more I realize that conspiracies actually do happen, but in much more subtle ways.
What actually happens is that over a long periods of time, people collaborate with and promote those who think like them, with similar biases and incentives. Then when a major decision needs to be made, everyone at the table think the same way and agree on the same solution. This works even across organizations, as people's career are made through networks and relationships transcending organizational boundaries.
It is difficult to get a group of people to understand something when all their salaries depends upon them not understanding it.
Some people end up coming up with conspiracy theories based on their outsider observations.
Of course if one tries pointing this out the response is sometimes "oh, they're so powerful that they like to mock us", but more commonly just to accuse you of being a shill/deep-state-agent/whatever.
To be clear, I don't think the Illuminati are real, but I don't think your reasoning is sound either.
Looks like it's already centuries old even, from 1600s Sweden: https://en.m.wikipedia.org/wiki/Axel_Oxenstierna#Quotation
Neither would I classify MK-Ulta that way: "Techniques included the covert administration of high doses of psychoactive drugs (especially LSD) and other chemicals, electroshocks, hypnosis, sensory deprivation, isolation, verbal and sexual abuse, as well as other forms of torture."
Or the releasing of biological weapons (MK-Naomi): "at least three covert techniques for attacking and poisoning crops that had been examined under field conditions."
Or Operation Notherwoods: "to both stage and actually commit acts of terrorism against American military and civilian targets, blaming them on the Cuban government, and using it to justify a war against Cuba."
Or the Tuskegee experiment: "The purpose of this study was to observe the natural history of untreated syphilis; the African American men in the study were only told they were receiving free health care from the Federal government of the United States."
The list goes on and on and on and on.
