Well worth the long read, even with the absence of a conclusion on either side of the imaginary dichotomy!
PS The results of MBTI can be replicated for free in your kitchen. Grab with your right hand as much custard as you can hold. In your left hand place an old fish. While concentrating on not dropping any custard, rate on a scale from ‘short’ up to ‘loud’, the relative smelliness of the fish. The resulting Custard to Smelly Fish Ratio can reveal amazing things about you. Send your CSFR to me, written on some high denomination currency and I’ll write back with an explanation. Don’t laugh, it’s equally valid as MBTI.
