Dualism is a somewhat technical term, I feel many people would refuse to answer because they just looked it up and do not feel sure to speak of it. I didn't presume a yes or no answer. If they say they believe in souls, my next question would be do you believe other entities eg animals etc can have souls? If they don't believe in souls I'd ask do you think its an architectural limit in current ais but are open to possibility of future ai being conscious. "do you believe thinking can be a property of matter"? this can work too, I think I have asked do you think there is supernatural element to thinking, I don't remember getting productive or straight answers either.

There is only one instance I recently remember I got a productive conversation, that person did believe ai could be conscious but didn't believe current architectures support it. (Obviously this aligns closer to my view, but I don't necessary NEED that you answer aligned to me, just saying you believe humans have souls and others can't have is still productive outcome to me and for onlookers.)

Yes I don't believe in souls either, and I would assumed that those who believe eg due to religion can just as easily state they do.
