implicit (prior) assumptions

I realised when being briefed about writing newspaper articles that there are some similarities with a statistical hypothesis and more generally similarities with anything that need to be `created'. By that I mean something that is created (superfically as new thing).

What I mean is this: For a new experiment there's assumption made even before you'd done anything. These assumption come from the simple fact that you'd decided to do an experiment in the first place. The motivation to do a particular experiment is already biasing the experiment. Out of all possible experiment, why was this one chosen? Even given the fact that the experiments aim to answer a particular question, then there would be more than one way to skin a cat i.e. the question could be answer in alternative ways. So, what the question is and how we decide to answer it e.g. what type of data do we collect and this is even before we start thinking about how to use the data.
The similarity with writing a newspaper article follows fairly obviously. How is it that one article is written over another hypothetical article? The simple fact that some one has chosen to write an article on a perticular subject has alrready biased the content. And this is before the `angle' of the piece is taken in to account.

Prior implicit assumptions are harder to pin down but are still important when considering the credibility, validity and bias of some knowledge.
