I think the JW mindset in conducive to conspiracy theories, because you already believe that whole sections of society can have a secret agenda, like scientists, that there is a secret knowledge and privelage said status to be had to feel you are lucky to know it when most of the world doesn't. All of this is about eg.
i went through it all as a JW looking for answers, about everything and everywhere. There was a huge appeal to thinking you knew something others didn't. But in reality, the people purporting these theories are not experts and in the vast majority, do not have grasps of the sciences, history or general accurate data.
Beyond a doubt a huge issue is the lack of ability to critically assess data. That is a life saving skill in an Information Age.
On top of all this, it is also great fun! Since being a young boy I was fascinated with radio at night, I felt like I was getting access to adult data, I was into talk radio, listened to it for decades. I used to stream Alex Jones, Art Bell Coast to Coast, James Whale, all of them, loved it, it was garbage, but back then in was enthralling.
