Abstract in brief

The Enneagram is a personality typology used by many for self-understanding and interpersonal insight, but its scientific validity remains questionable.
Research shows mixed results regarding its reliability and validity, with some factor analyses partially aligning with theoretical models and its relatedness to other personality measures like the Big 5.
Most studies have not strongly supported the core nine types or secondary concepts like wings and intertype movement, suggesting a need for more rigorous research and clearer clinical applications in the future.]

@pompom9211 @AjaxtheGriff Call me a degenerate but there is something to the Enneagram. We need more studies and clustering work needs to be done to get evidence for the 9 types. https://t.co/du1bQ9HxpB
