There is more public awareness of MBTI than there was in, say, the mid-1980s when Please Understand Me was published.
At the same time, it has been dismissed by those reductionists who make the clinical with peer review their God. These are those who are uncomfortable with mystery, and ambiguity. They prefer questions which have an answer, as opposed to those which give rise to further questions.
And of course, as it happens with all psychometric and diagnostic typers and criteria, over time it becomes a pop psychology and a slur, e.g., cretin, nimrod, and retard.
I also think MBTI would be given greater consideration (in the current context) if it had moved beyond description of the normative, and incorporated aspects of shadow presentation and work which would speak to trauma, schema, and maladaptive behaviors.
Those who are too comfortable with black and white thinking toss it out, just as they do with things like comparative religion and IQ. Those who are more fluid in their ascertainment, and live in a world of varying hues, have room for MBTI. Because they understand the limit of its utility, they by turn know its utility, and put it to use as they may.
So it goes with any heuristic tool. Scorn from those with no insight, and a wink and a nod from those who do.
Cheers,
