When someone asks for our opinion and we answer the question with the phrase "I don't know?", what are we actually saying? Do we actually have no idea what so ever (which would be an accurate use of the phrase) or are we using it to keep us from being wrong? Often times, people say "I don't know" to a question about their opinion, in order to avoid commitment. By saying "I don't know", the door is open for the person who asks the question to give the answer and allows the initial "responder" to avoid having a "wrong" opinion. The unfortunate situation is that the "responder" does not have the opportunity to be correct, either. Also, "I don't know" is a lazy response. It leads us to believe that the person hasn't put any thought into the question or the potential options. "Why do you think today was such a bad day"? The question asks for an opinion ("What do you THINK ..."). "I don't know". Well, then how do you expect to learn from today to make tomorrow better? There are many reasons why someone may have a bad day. Some reasons are under their own control and others may not. It could also merely be an attitude. Whatever the reason, "I don't know", does not allow for growth. Answering incorrectly at least rules out some options. "I don't know" is an acceptable answer to a question for a specific fact but when we are asked for our opinion or thoughts on a subject, "I don't know" is lazy and prevents our own growth.
