General Questions are Hard

I talked to one of the professors in applied mathematics to discuss my research question, and the topic of 'information' (in the statistical context) came up. I've heard about Information Theory from my boyfriend, because he is currently taking the class. He has told me that the subject is very abstract and heavy in probability theories. Anyways, professor explained how people started to question how to measure 'information' in an more objective way, and that led to theorizing on it. I thought that the more general or low-level our question is, the more difficult theorizing it is. Answering a general question, in most of the aspects of life, is difficult.
