In politics, centrism or the centre is a political outlook or specific position that involves acceptance or support of a balance of a degree of social equality and a degree of social hierarchy; while opposing political changes which would result in a significant shift of society either strongly to the left or the right. Centre-left and centre-right politics both involve a general association with centrism combined while leaning somewhat to their respective sides of the spectrum. The term is often used interchangeably with the Third Way, a political position popularized by Bill Clinton, Tony Blair and Paul Keating in the 1990s, whereby policies favored a balanced approach and the removal of extreme ideologies.
