I'm don't believe in conspiracy theories however, because I'm mature enough to accept that sometimes bad things happen for reasons other than "evil underground cabal of satanists".
especially this one - these people seem like they're in denial about their actions causing climate change causing their catastrophic weather, so they invent invisible bogeymen to blame.
I imagine that when they get dumped by their girlfriend, they'll blame it on George Soros manipulating her via 5G raditation instead of "well maybe she didn't like you being an abusive alcoholic who cheated on her?"
My friend works in IT and earns probably in the 99th or 98th percentile in the country. It's not that. In fact I don't think economic wellbeing is related at all. Poland has been doing great economically for the last 30 years, and yet the conspiracy theories are spreading.
I mostly blame social media. Previously if you wanted to know how the climate works you looked it up in encyclopedia, watched some TV or asked a teacher. They mostly weren't spreading bullshit.
Now you search internet and there's so much bullshit confirming all your wrong ideas you can spend weeks reading just that.
I also know a huge amount of conspiracy theory believers in the medical area. Also otherwise competent.
If anything, the correlation with loneliness or low status was reverse: the richer and high-status, the more blatant and visible those beliefs were. People in low-prestige professions, or poor? It was very rare to see them talk about it.
