Decisionmaking Questions re Issues, Ideas and Causes

For me (and maybe some of you) these are really important questions:

How do you decide:
1. What issues, ideas and causes you take a clear position on?
2. What issues, ideas and causes you admit you don't know the answer to or are reexamining your position on?
3. What issues, ideas and causes do you prioritize -- either to study and understand better, or to promote a certain answer or approach to?
4. As a leader how do you balance the need to be a. consistent or b. growing and changing?

In deciding this, which of these decisions do you make:
1. alone (or with God)
2. with your spouse or family
3. with some form of community
4. by default (because you've been taught it or you're part of a community that has a "required" viewpoint on the subject)
