Slippery slope refers to a belief that often is fallacious, but not always.


With the slippery slope the person will not take an action or let it occur, because s/he believes that this will lead inexorably to a bad end. This is likened to starting to walk down an icy hill.


The classic slippery slope is a single, continuous slope. An alternative is the slippery stairs, with the downward trajectory involving a series of separate stages.
