I think the problems and solutions that may seem plagued by Forer effect are mainly due to incapability of formal and natural languages to describe and evaluate the data.
Humans are very hard to be described with words. The problem applies to all personality systems, and even to astrology and the like. The truth is that
we simply cannot test such systems properly (for now). We rely on our common intuition more than reasoning.
It's similar to the continuous/discrete, or analogous/digital problems of translation. Reality sometimes is far more complicated than any amount of words could describe.
As an illustration, one of my favourite photo effects "halftone" - here's a couple of years old picture of myself with such effect:

That's how far our textual descriptions are from some aspects of reality, as far as I'm concerned.
