Not sure if you mean it inaccurately predicts human cognition, or it
correctly predicts logically erroneous human cognition. My point, and
I think Richard's, is that such artificial and contrived challenges,
while of course valid in their own terms, miss the complexity and
everyday utility of extrapolating from exemplars, especially when an
abundance of apparently salient information is available. "Q: Give
the foregoing information, is Esmeralda a living human, or is she on
the planet Earth, or is she a [living human] deeply politically
concerned feminist [on the planet Earth]?" "A: If not the latter, why
the hell did you just front-load me with all that misleading priming
information? Have you never heard of conversational implicature, you
twisty weasel?"
