Of the more than 10,000 papers published on AGNs since the discovery of quasars in 1963, only just over 100 mention polarization. Yet these 1% of papers reveal highly non-spherical structures in AGN in a way not available by other means. Here these polarization properties are reviewed and their implications discussed. Each of the complex set of observational polarization properties of AGNs are generally treated as independent scatterers. Yet this is highly unlikely, and Occam's razor points toward simpler explanations. One such explanation is put forward, and the implications for X-ray polarimetric observations discussed.
