Sometimes, having a quick, inaccurate, but easily-verifiable answer is better. For example, when you're trying to remember the name of that one function to call, or ideas on where to travel next month.

Also, not super relevant, but in e.g. combat situations one is often better off running now in any direction rather than pondering which direction is absolutely optimal for running from the lion. You'll know soon enough whether it was the right direction. There's probably a metaphor somewhere in there.
