In Infinite Love is the Only Truth (2005), Icke introduces the idea of "reptilian software." He says that there are three kinds of people. The highest level of the Brotherhood of the Snake are the "Red Dresses." These are "software people," elsewhere called "reptilian software," or "constructs of mind." They lack consciousness and free will, and their human bodies are holographic veils.
A second group, the so-called "sheeple"—the vast majority of humanity—have what Icke calls "back seat consciousness." They are conscious, but they do whatever they are told and are the main source of energy for the Brotherhood. They include the "repeaters," the people in positions of influence who simply repeat what other people have told them. Doctors repeat what they are told in medical school and by drug companies, teachers repeat what they learned at teacher training college, and journalists are the greatest repeaters of all.
The third group, by far the smallest, are those who see through the illusion; they are usually dubbed dangerous or mad. The "Red Dress" genetic lines keep obsessively interbreeding to make sure their bloodlines are not weakened by the second or third levels of consciousness, because consciousness can rewrite the software.
