One (Enneagram)

Ones, in Enneagram of Personality teaching, are people of the psychological type represented by point number one on the Enneagram figure.

According to the Enneagram of Personality there are nine interconnected ego and archetypal psychological types. Although the nine Enneagram types are usually called 'personality types' (or 'character types') they are now increasingly called 'Enneatypes'.

Enneagram of Personality teachers also often use other words to describe certain distinctive characteristics of each Enneatype. Enneatype Ones are sometimes referred to as 'reformers', 'perfectionists' and other terms that seek to indicate their more distinctive personality motivations.
