Opinion

In general, an opinion is a belief about matters commonly considered to be subjective, and is the result of emotion or interpretation of facts. An opinion may be supported by an argument, although people may draw opposing opinions from the same set of facts. Opinions rarely change without new arguments being presented. It can be reasoned that one opinion is better supported by the facts than another by analysing the supporting arguments. In casual use, the term opinion may be the result of a person's perspective, understanding, particular feelings, beliefs, and desires. It may refer to unsubstantiated information, in contrast to knowledge and fact-based beliefs.

Collective or professional opinions are defined as meeting a higher standard to substantiate the opinion. (see below)
