Those are good points, but what strikes me as utterly silly in what most every critic of the model say is that they threat the four letters as four axes and go from there.
They aren't. The Jungian model doesn't say, for example, that Extroversion and Introversion are one axis. It says there are four extroverted functions, and four introverted functions. Each extroverted function forms three axes: one with its introverted version, another with its opposite function in its extroverted version, and another with its opposite function in its introverted version. The letter "I" or "E" at the beginning of the four letters type tells you which of your two main functions (one of which is extroverted, the other is introverted) is the primary.
So it absolutely obvious, from the mere description of what the first letter alone means, that it won't map to the Extroversion axis of the Big Five model, and any correlation found between both won't be strong.
And yet, every single criticism of MBTI I find, and every single study trying to correlate both, present the E/I letter pair, and the Extraversion axis, should behave roughly the same, and point to them not correlating strongly (but stronger than other such not-axes pared to axes) as if this was a very important finding.
So I do take issue with how psychologists approach this. It's pretty evident they start by paying zero attention to whatever Jung wrote (irrespective of MBTI, for which I care little), then test a strawman they made, and prove this strawman is false. Which says nothing about the Jungian model itself, as it wasn't tested.
What I want to see is someone reading Jung, developing a psychometric test of what he was actually saying, and testing that one. I'm yet to see anything of the sort made, whether by proponents of by critics, I don't care which.
