Hanlon's razor ("never attribute to malice that which is adequately explained by stupidity") applies to much more than most people seem to think. If humans were capable of scheming half of the stuff that's attributed to conspiracies we'd be a multi-planetary species by now. Nah, usually it's not a big bad plan by a big bad shadow cabal, people were just dumb and fucked up, or got unlucky and failed to prepare for it, or both.
