It's funny because recently I wanted to learn about the history of intellectual property laws in China. DeepSeek refused the conversation but ChatGPT gave me a narrative where the WTO was essentially a colonial power. So right now it's the American AI giving the pro China narratives while the Chinese ones just sit the conversation out.

Then, you introduce the bias into relative unknown concepts that no one prompts for. Preferrably, obscure and unknown words that are very unlikely to be checked for ideologically. Finally, when you want the model to push for something, you introduce an idea in the general population (with a meme, a popular video, maybe even an expression) and let people interact with the model given this new information. No one would think the model is biased for that new thing (because the thing happened after the model launch), but it is, and you knew all along.

The way to avoid this kind of influence is to be cautious with new popular terms that emerge seemingly out of nowhere. Basically, to avoid using that new phrase or word that everyone is using.
