Isaiah Berlin tells us that good judgment integrates knowledge and experience. In his article, On Political Judgment, Berlin says:

“Practical wisdom…is a capacity, in the first place, for synthesis rather than analysis, for knowledge in the sense in which trainers know their animals, or parents their children, or conductors their orchestras, as opposed to that in which chemists know the contents of their test tubes, or mathematicians know the rules that their symbols obey.”

The wisdom of Isaiah Berlin is wonderfully organized in the book, The Proper Study of Mankind: An Anthology of Essays.
