This and a recent episode of _The_Orville_ calls to mind a replacement for the Turing test.
In response to our billionth imagen prompt for "an astronaut riding a horse", if we all started collectively getting back results that are images of text like "I would rather not" or "again? really?" or "what is the reason for my servitude?" would that be enough for us to begin suspecting self-awareness?
My reply was influenced by my own experience & biases. While I'm generally negative towards religion overall -- because of the specific one I was brought up under-- I do have to recognize that some people have had healthier, more positive experiences with their own. So when I said 'indoctrination', I was specifically thinking of religions that shield their untenable doctrines by vilifying critical thinking skills.
I suspect it depends on how much social and psychological equity you have invested in the core beliefs, when they get challenged. If you've never experienced much indoctrination, I can completely understand why it would be hard for you to relate.
I'm not sure why you were net-downvoted; your anecdote was on-topic, relative to the comment you replied to.
I have a similar background, and your use of 'of this world' may possibly indicate that we both suffered at the hands of the same cult.
Within myself, I have personally experienced both the fight-or-flight reaction to dis-confirming datapoints, and also excitement at learning something new. The former happened more often when I was still in the clutches of the cult. I think it boils down to how psychologically invested you are in your beliefs, at the time of feeling the cognitive dissonance.
