Devil's advocate
In common parlance, a devil's advocate is someone who, given a certain argument, takes a position they do not necessarily agree with (or simply an alternative position from the accepted norm), for the sake of debate or to explore the thought further.
In common parlance, a devil's advocate is someone who, given a certain argument, takes a position they do not necessarily agree with (or simply an alternative position from the accepted norm), for the sake of debate or to explore the thought further.
In taking this position, the individual taking on the devil's advocate role seeks to engage others in an argumentative discussion process. The purpose of such a process is typically to test the quality of the original argument and identify weaknesses in its structure, and to use such information to either improve or abandon the original, opposing position.
It can also refer to someone who takes a stance that is seen as unpopular or unconventional, but is actually another way of arguing a much more conventional stance.
