I tested this by asking GPT to create an imaginary country and government. I prompted it to create it's laws and constitution. In some cases cultral beliefs too. There where many cases where it outright refused to come up with hypothetical laws or cultral stances on certain issues. I eventually accused it of creating a straw man when it didn't want to give a solid answer (it would always weasel around it). It apologised and essentially shrugged.
