Unintended consequences

Because we mostly react instead of think, our actions are based on insufficient information. We grab for a solution without thinking deeply about the context of the problem: e.g: We try to cheer up a depressed person by making her realize that her life is not that bad and that the sun is shining, only to find out we have made her even more depressed. She now feels guilty about her feelings, worthless, and more alone in her unhappiness.
