I'll side with those who go with the "gut feeling", instinct, and subconscious.
When I was younger, I was scared to death making decisions, even the trivial ones. Then I learned about some decision making techniques. Then I learned some intuitive making techniques. While my life progressed, I noticed, that even if I make a decision I regret at first, it all turns out fine in the end. I don't know how - it is a miracle.
So at the moment I can' say I make any decisions at all. I just follow the flow, the next actions are pretty obvious for me.
Since I do not fear the outcomes, I do not spend much thought for alternatives.
If I start going along some path, and it leads to a dead end, I always have time and resources to alter the situation to the best.
