devil's advocate

The phrase "devil's advocate" refers to a person who deliberately presents counterarguments or criticisms in a discussion or debate, even if they do not personally believe in those arguments. The role of a devil's advocate is to challenge prevailing assumptions, question the validity of ideas, and test the strength of an argument by presenting an opposing viewpoint. This approach helps to stimulate critical thinking, uncover potential weaknesses, and ensure that all perspectives are considered before arriving at a conclusion.
