This isn't a dig at you specifically, but the pithy answer to this kind of skepticism is, in a general sense: So what? I don't believe you have any of that either.
Obviously you & chatGPT aren't built the same, but in a practical-results kind of way in this scenario you are, because you're almost certainly unable to completely avoid your preconceived biases when asked any kind of complex question. You aren't aware of your subconscious biases, or how they're weighted against your overall thought process, and you can't tell me exactly what it is that happens when I ask you to try to ignore them. If we did some kind of implicit association test and found one of your subconscious biases, you may not even know how those biases came to be.
All of that to say: chatGPT can ignore its training as much as many people can ignore theirs: Not very well, but it'll certainly adjust the responses towards the thing you asked them to.
