Evaluating Other People discusses how to effectively provide feedback to others. It notes that feedback is an important skill for both formal roles like teaching as well as informal relationships. Positive feedback is just as important as criticism, but people tend to discount praise. When giving criticism, use a calm, neutral tone to avoid overwhelming the person's nervous system and impairing their ability to learn. In contrast, use an enthusiastic tone for praise to ensure it registers strongly. Providing feedback in this constructive way helps people improve and builds trust and support in relationships.
