In the novel trilogy (and the plays), the interjection "fnord" is given hypnotic power over the unenlightened. Under the Illuminati program, children in grade school are taught to be unable to consciously see the word "fnord". For the rest of their lives, every appearance of the word subconsciously generates a feeling of unease and confusion, preventing rational consideration of the text it appears in. The uneasiness and confusion create a perpetual low-level state of fear in the populace. The government acts on the premise that a fearful populace keeps them in power.
