Can observation be a good starting point the selection of a topic?

The starting point for any science is systematic observation. As we accumulate knowledge and propose explanations, the observations become more detailed, we look for things that we did not know to look for before, and we pay more attention to the conditions or context in which the observations occur.

depends on what they need

1. state-issued photo ids. provide them for free for those who can't afford them.

2. the system we have seems to be working nearly perfectly. seems like about 31 cases per billion votes cast

3. the national policy for hiring new employees which requires proof of eligibility to work. there are something like 20 types of identification which can be used for this.
