This idea was surprising to me too, but when I thought about it I realised it shouldn't be:
- We know that different people frequently react differently to the same stimuli (and that this is true even of very young children).
- Basically everything else in the human body shows genetic variation. It would be weird if the brain didn't.
- There is a strong evolutionary rationale for a population having a variety of complimentary congnitive styles.
I think the MBTI is most interesting is it taken to be only the genetic component of personality (providing us with AFAIK the only theory of the structure of that aspect of personality), while simultaneously leaning into the idea that personality is modified by nurture and environment (but that these changes are not described by one's MBTI type).
