This post is a follow up to the previous post on judging favorably concerning other persons, the related video on seeing the best in them, and also occasioned by a discussion on another blog (platitudes in attitudes, no longer online).
The fact is, if we are inclined to the more favorable judgment in matters where the truth is unclear, or to the extent that the truth is not perfectly clear, we will also overall be more correct, not less. If someone says something that seems false, we are more likely to understand them correctly if we suppose that they have some reason for saying what they do. Similarly, if we see someone do something that seems bad, and don't know their intention, it is not only more charitable, but probably more truthful, to suppose that they have some good intention.
