It is rational to not waste time and energy thinking about things that are unlikely to matter. Being rational doesn't mean that you always make the correct choices according to some artificial metrics, it means that you make the correct choices based on the information available to you and your goals. Intuition and folk tales is a part of the information available to you, so keeping them in mind is a part of being rational (although you shouldn't put too much weight on them either).
