Assuming one must first conceive of deception before deploying it, one needs not only self-awareness but also theory of mind, no? Awareness alone draws no distinction between self and other.
I wonder however whether deception is not an invention but a discovery. Did we learn upon reflection to lie, or did we learn reflexively to lie and only later (perhaps as a consequence) learn to distinguish truth from falsehood?
I think that deception can happen without even a theory of mind. Deception is just an anthropisation of what we call being fooled by an output and thinking the agent or nodel is working. Kind of like how in real life we say animals are evolving but animals can't make themselves evolve. It's just an unconcious process
