The is-ought fallacy occurs when the assumption is made that because things are a certain way, they should be that way. It can also consist of the assumption that because something is not now occurring, this means it should not occur. In effect, this fallacy asserts that the status quo should be maintained simply for its own sake. It seeks to make a value of a fact or to derive a moral imperative from the description of a state of affairs.
