The best way to read someone else’s emotions is by listening to their voice instead of looking at their face. Studies have shown watching a person’s facial expressions, even when also focusing on their voice, can be misleading if you are trying to figure out how they really feel. People are skilled at masking their facial emotions, so paying closer attention to what is said and how they are saying it gives fewer mixed cues and can help you analyze their feelings more accurately.
