It is about an Enneagram, but not based on the actual Enneagram. It is a sucker punch at anyone who actually wants to learn the basics of why certain fundamental personality behaviors become evident in some people, and it is a sucker punch because Naranjo didn't care to actually understand the Enneagram as he read it in the first place, he skimmed right through it, and then wrote down his own warped observations, and wrong observations at that. Naranjo focused on the black and white and labeled a maximum of 9x3 total human personalities, saying E1 think they are holy, E2 are housewives of the year, E3 are narcissists, E4 are crybabies, E5 are not social, E6 are paranoid, E7 are hyper, E8 are psychopaths, and E9 are fat (I'm not fat, so I can't be E9-- lol), inane stereotypes, which still has residues in pretty much all of the current known descriptions online. The only thing Naranjo is famous for is self-effing his own name into wikipedia.
