“…I separately consider voting and opinion-writing behavior for dissents and concurrences for two primary reasons. First, the norms of consensus that governed when and how justices could distinguish themselves from the majority coalition have changed across time so that presently justices are less inhibited from concurring or dissenting than previously (Caldeira & Zorn, 1998;Haynie, 1992;Hurwitz & Lanier, 2004Lanier, 2003;Maveety, 2003;O'Brien, 1999;Turner et al, 2010;Walker, Epstein, & Dixon, 1988). These norms changed to first accommodate the justices' voice of dissensus generally and then they changed once again to allow their publication of concurring opinions and then later dissents.…”
