Pseudoscience often rebrands itself under new names but never really goes away. Some people not only believe in acupuncture, they even believe in acupuncture for their coffee grinds. Other things have even less evidence, like chakras, astrology, and their more modern weird love child, the Enneagram.

Like The Flu Fighter Martini, just because Enneagram numbers are in The Guardian, official media outlet of the anti-science left, does not make any of it legitimate.

If you don't venture into the goofier realms of the anti-science movement - that is why you have Science 2.0 to do it for you, after all - Enneagram is basically pop psychology warmed over from the 1970s, when universities chasing student money even had paranormal labs, because the paranormal was a big craze. Armenian mystic George Gurdjieff came up with the term and then future generations fleshed out his spiritual belief that we have 9 personality types, things like Reformer and Helper and Peacemaker. Those all sound pretty good, right? Of course, like astrology, everyone has to see something they identity with regardless of which type they are, and they all have to be positive.

After that came a 'personality' assessment, invented by a 1970s (nothing more needs to be said) psychiatrist, whose precepts have been repeatedly debunked. 

The only vindication has been anecdotal that it helps with "spiritual growth" but even that is just surveys of people who believe in it claiming it helped them grow spiritually, whatever that means. if you do an unweighted meta-analysis of surveys of people who swear strawberries labeled organic prevent autism, you'd get statistical significance showing that strawberries using old-timey pesticides prevent autism.

But like all fads, it will probably have its die and Enneagram has gotten so big among progressives that even Babylon Bee has noticed:
