Gut feelings.

Three factors come into play in decision making for everyone: logic, data, and gut.

You should continually learn about the world and your place in it by gathering data. This data can be analyzed to help you make decisions. And target specific data to add when confronted with a challenging decision. But data analysis is inherently flawed when decoupled from logic. The data may be telling you one thing, but you could have insufficient data, be mistaking correlation for causation, experiencing a Simpson's Paradox, or be in any other number of fallacies or paradoxes. If analysis results seem illogical, you should probably dig deeper. Likewise, analysis can prove, disprove, or help you refine your logic. 

This is often where people stop. But where do your gut feelings fit it? Some would argue that they should have no place in rational decision making at all. I disagree. Gut feelings are often your reaction to unanalyzed data or uncriticized logic that you've collected over time. So if your gut is telling you something, you should dig deeper into that feeling to logically explore where it is coming from. The results of this exploration can either prove your gut feeling right if there was some piece of data or logic that you had been ignoring, or prove your gut feeling wrong due to some flawed logic or incomplete data that was subconsciously weighing on you.

I would add that particularly weighty decisions also require prayer and God often points things out to us through our gut.
