The Bolivian-born Ichazo began teaching programs of self-development in the 1950s.
His teaching, which he calls "Protoanalysis", uses the enneagram figure among many other symbols and ideas.
The types are normally referred to by their numbers, but sometimes their "characteristic roles" (which refers to distinctive archetypal characteristics) are used instead.
Various labels for each type are commonly used by different authors and teachers.
Ichazo disowned Naranjo and the other teachers on what he felt were misinterpretations and uses of the Enneagram.
For some Enneagram theorists the lines connecting the points add further meaning to the information provided by the descriptions of the types.Sometimes called the "security" and "stress" points, or points of "integration" and "disintegration", some theorists believe these connected points also contribute to a person's overall personality.From this viewpoint, therefore, at least four other points affect a person's overall personality; the two points connected by the lines to the core type and the two wing points.While Enneagram teachings have attained some degree of popularity, they have also received criticism including accusations of being pseudoscience, subject to interpretation and difficult to test or validate scientifically.The scientific skeptic Robert Todd Carroll included the Enneagram in a list of pseudoscientific theories that "can't be tested because they are so vague and malleable that anything relevant can be shoehorned to fit the theory".]), is a model of the human psyche which is principally understood and taught as a typology of nine interconnected personality types.Although the origins and history of many of the ideas and theories associated with the Enneagram of Personality are a matter of dispute, contemporary Enneagram claims are principally derived from the teachings of Oscar Ichazo and Claudio Naranjo.It is believed people function in all three forms of instinctual energies but one may dominate.According to some theorists, another instinct may also be well-developed and the third often less developed.Naranjo's theories were partly influenced by some earlier teachings of George Gurdjieff.As a typology the Enneagram defines nine personality types (sometimes called "enneatypes"), which are represented by the points of a geometric figure called an enneagram, In business contexts it is generally used as a typology to gain insights into workplace interpersonal-dynamics; in spirituality it is more commonly presented as a path to higher states of being, essence, and enlightenment.
