Yea, that's what I'm saying. They didn't specify rules such that the information revealed by these four cards would allow a person to infer the rules for the whole deck but such rules could have been stated. It would be possible to disprove the rule but any number of convoluted rules could be applied to the deck that wouldn't hold for the proposed "rational" conclusion. I am guessing the person who wrote the test left some conditions out.
