Moderation is the process or trait of eliminating, lessening, or avoiding extremes. It is used to ensure normality throughout the medium on which it is being conducted. Common uses of moderation include:
- A way of life emphasizing perfect amounts of everything, not indulging in too much of one thing.
- A moderator may remove unsuitable contributions from the website, forum or chat room they represent in accordance with their moderation system.
- Ensuring consistency and accuracy in the marking of student assessments.
- A "moderator" is one name for the formal position of one who presides over a discussion, helping to ensure that the discussion is balanced among its many voices, for example in the Methodist church's use of the term for the heads of its conferences.
- A neutron moderator is used to slow down neutrons in a nuclear reactor.
