In my experience, especially engineers are very likely to be sucked into this. More especiallier, retired engineers.

Engineers are basically taught, that a) the entire world is a clock waiting to be understood and b) they are the smartest persons in most rooms, which makes them the only ones who are capable of understanding the clock.

Their entire life is solving problems which are clear cause/effect relationships, and most importantly: solvable by them. So they start to think exactly like that. And if you look into the internal logic of conspiracies, it's always clear cause and effect. Things don't "just happen", they always have someone responsible.
