Programmers do it too. it is called 'narrowing down the error margin'. sometimes they ever do it with random course changes (and then check to see which side of the line they landed on) that is called 'drunkards walk'.
It can be helpful, even without an enemy to awoid.

Yes. This is mulling, fretting, or brooding. How many times do we make a quick decision and then decide we should consider it a bit more. We struggle and think of every possible outcome and, in the end, go back to our original choice. I'm not saying we should never do this.
Actually ... scientific research has shown that men think linearly, while women think intuitively. This is why men are generally better at math, and women are generally better at relationships.
