How did you hear about pakistani food? Where did you hear about Pakistan recently enough to recall it? Was it food related or not? If you look deep enough, yes sometimes unconsciously, we make these decisions that seem random but they are not. In a real scenario, not one just made up for the sake of debate, theres gonna be underlying reasons for your "random" choice. You could even try your darndest to be random and choose the first thing that comes to mind but you are still digging for things that it ties to "that would be unlikely therefore random" when in reality its just a word or concept you've unconsciously defined as unusual or different. I don't think there is a human element or ability to choose chaos like you think there is. It just appears that way because thats the only way we are capable of perceiving it
