'''Attitude polarization''', also known as '''belief polarization''' and '''polarization effect''', is a phenomenon in which a disagreement becomes more extreme as the different parties consider evidence on the issue. It is one of the effects of ''[[confirmation bias]]'': the tendency of people to search for and interpret evidence selectively, to reinforce their current beliefs or attitudes.<ref>{{wikicite|id=idFine2006a|reference=Fine, Cordelia (2006a).
