Question: How much confidence should a person express in her own opinions? I work with a woman who constantly makes declarative statements about things for which she lacks sufficient facts and knowledge. The result is that she is often contradicted and people have to tell her, "That's not true." She will argue with them and then they have to prove her wrong so that the conversation can move forward. By contrast, I've noticed that I often express uncertainty in ways that undermine confidence in my knowledge and experience. The default position I tend to take is that maybe I am missing something and the other people in the conversation can give me that information. How does one learn to strike the right balance between being open to new facts and information but also being confident in one's own knowledge and experience?
