Rav Nahman makes a good point about אמונת חכמים--faith in the wise. But I think one needs to develop a certain kind of common sense to know in what exact points the sage was correct and to be able to filter out the areas where he might have been wrong.
In universities it is common to give advice to students to think for themselves. Read the material and come to their own conclusions. However how would this work if you are in a hospital? What would be the best approach? Listen to the doctor? Or think for yourself and come to your own conclusions?
Sometimes however even experts can be wrong.
You need some kind of common sense to tell when it is best to listen to the experts and when to develop your own approach.
