The theories are often complex from the standpoint of how they work, or even the motivations. They are simple un how they assign blame. We all like having goodguys and badguys neatly separated with a single linear function. That is much more appealing than admitting we are all partly to blame for pretty much everything that affects all pf us, and that even the worst actors often have some good motivations and qualities. In addition to the appeal of simple humans, the complex conspiracies seem to appeal to people with very good pattern matching intelligence. Also, sometimes, conspiracies are real, and that doesn't help.
