> The problem with these questions is not that they are necessarily hard to answer (often they are) but that people don't even know, that they need to be asked in the beginning. Right. And what makes it even more problematic is that answers to these questions affect what answers are possible to other questions. So it is not the sum of the difficulties of the answer to each question but their product, the combinations of different possible answers.
