Boy is that a dismissive overstatement. Briggs began thinking about personality in 1917, intentionally read biographies to get more data on personalty, and incorporated Jung's ideas in 1923 when his book was published, albeit with her own interpretation. Meyers did an apprenticeship with a test developer to learn how to make tests. So both Meyers and Briggs were, in fact, reasonably well versed in the field. They did not even make the test until 1944, after they'd been thinking about these ideas for over 20 years. Note that the Big 5 was not developed until the 1980s, almost half a century after they developed their theory. Ass-pulling this is not.
Wikipedia hates on the MBTI, but the actual test that you have to pay for is hardly "Barnum effect, flattery, and confirmation bias": you have 50 or so questions that you have to choose between two options of what you do. Now, you do have to answer what you actually would do rather than what you think is best or what you should do or what you should do culturally, so there is some confounding effects there.
More recently I’ve been considering neuro-divergence in the context of these personality types. Specially ADHD and Autism. ADHD by example has a whole system effect for someone, with resultant strengths and challenges very much informing part someone’s personality.
Folks with Autism often have traits of being: direct, seek deep details, are able to stick with a few topics to deep excellence, can sometimes struggle reading people’s emotions.
And yes while generalisations, I wonder on how different neurodivergence’s may be hiding in plain sight within some of these personality systems.
I’ve def seen jokes online that notice that certain MBTI profiles are commonly gateway diagnosis for say ADHD/Autism.
