No, you are misinterpreting the conjunction fallacy. If someone assigns a greater probability to the claim that “humans are conscious and rocks are not” than to the claim that “humans are conscious”, then this will be the conjunction fallacy. But it will also be the conjunction fallacy to believe that it is more likely that “physical systems in general are conscious” than that “humans are conscious.”
The conjunction fallacy is basically not relevant to comparing “humans are conscious and rocks are not” to “both humans and rocks are conscious.”

Indeed. Thank you.

Forget humans for a second. Just focus on the statement “only physical systems in a particular type of configuration will be conscious”; without knowing which type you mean. You cannot assign a higher probability to any particular system without already having some deciding criteria. It’s when you fix your deciding criteria on the statement “x is human” that the conjunction fallacy comes back on you.
Ofcourse it’s not more likely for a human and a rock to be conscious than just for the human, you have to grant the latter just to avoid being obtuse. But who’s arguing that being human is the deciding criteria for whether a system may be conscious? That’s defenestrating any hope of investigating the phenomenon in other systems which does not do much to assist an empiricist framework for it.
“Only humans are conscious” should indeed have a lower prior probability than “Only physical systems specified in some way are conscious”, since the latter must be true for the former to be true but not the other way around.
However, whether or not only humans are conscious is not the issue. Most people think that many or all animals are conscious, but they do not think that “all physical systems are conscious.” And this is not because of the prior probabilities, but is a conclusion drawn from evidence. The reason people think this way is that they see that they themselves appear to do certain things because they are conscious, and other people and animals do similar things, so it is reasonable to suppose that the reason they do these things is that they are conscious as well. There is no corresponding reason to believe that rocks are conscious. It is not even clear what it would mean to say that they are, since it would take away the ordinary meaning of the word (e.g. you yourself are sometimes conscious and sometimes not, so it cannot be universal).
“Only humans are conscious” should indeed have a lower prior probability than “Only physical systems specified in some way are conscious”
Yes, but not lower than “only physical systems specified in some way are conscious, and that specification criteria is not “x is one of {human, dog, parakeet...}”″. If your idea of a “particular configuration” is a defined by a set of examplars then yes, “only physical systems of some particular configuration” follows. Given that, as you yourself say, whether humans are conscious or not is not the issue, we should consider “particular configurations” determined by some theoretical principle instead. And it seems to me my original argument concerning the conjunction fallacy does hold, given these caveats.
It is not even clear what it would mean to say that they are
That I must concede. But it’s not clear what it means to say a human being is conscious either (were it clear, there would not be so many impenetrable tomes of philosophy on the topic). Ofcourse it’s even less clear in the case of rocks, but at least it admits of the possibility of the rock’s inherent, latent consciousness being amplified by rearranging it into some particular configuration of matter as opposed to flashing into awareness at once upon the reconfiguration.
