Don't mean to bring up 'old wounds' regarding the J/P thing; I'm just describing what I'm hearing people say.
Yeah, I know.

The idea of INTjs showing P-like attributes just won't go away easily on the forum, or in Socionics literature.
I agree with your general way of seeing it. I'm just trying my best to re-phrase the arguments so that maybe those who have such ideas eventually will start seeing what's wrong with them.

The quadra descriptions and functional descriptions that lead in that direction are ubiquitous in Socionics, even as the Socionics understanding of rational/irrational leads in the opposite direction. Hence, the contradictions are "built in" to the system.
Yes, clearly so. And for some obscure reason I don't like contradictions.
