In fact, that is the pattern:
People face a situation that is confusing or seems incomprehensible and then they look for a way to assign blame.
It is easier to grasp a conpiracy theory when people you identify with—people who share your political and moral views— are doing the same.
It feels good to belong to a community of like minded people, so if a wrong idea catches hold in your group, you are more inclined to go along.
