Absent hypotheses do not produce evidence. Often (in some cases you can notice confusion but it is hard thing to notice until it up in your face) you need to have a hypothesis that favor certain observation as evidence to even observe it, to notice it. It is source for a lot of misunderstandings (along with a stupid priors of course). If you forget that other people can be tired or in pain or in a hurry, it is really easy to interpret harshness as evidence in favor of “they dont like me” (they can still be in a hurry and dislike you, but well...) and be done with it. After several instances of it you will be convinced enough to make changing your mind very difficult (confirmation bias difficult) so alternatives need to be present in your mind before encounter with observation.
Vague hypotheses (“what if we are wrong?”) and negative (“what if he did not do this?”) are not good at producing evidence to. To be useful they have to be precise and concrete and positive (this is easy to check in some cases by visualisation—how hard it is to do and if it even possible to visualise).
