How often do you add noise to your search queries? What sort of noise to add (whether it's truly random or based on your subconscious) is another matter.
There are extensions which can do it for you. I don't bother, because I'm using ddg for search. One can whip up something similar for llm-s as well and I'm sure that soon someone will right one for chat gpt. This will avoid the subconscious bias.
