“…On the other hand, several studies have failed to uncover evidence of a critical mass threshold (Bratton, 2002;Bratton, 2005;Reingold, 2000;Weldon, 2006), with some finding that the context in which they make their decisions and within-group differences among women are more important in conditioning and explaining women policymakers' effects on policy outputs than sheer numbers (Holman & Mahoney, 2018;Osborn & Kreitzer, 2014;Poggione, 2004b;Reingold & Smith, 2012). These findings have led some scholars to question the idea of critical mass, with many critics attributing the theory's shortcomings to its treatment of women as monolithic actors and consequent failure to account for how intergroup differences, as well as varying political and institutional factors, may lead to women to develop different policy preferences or solutions regarding women's policy concerns (Beckwith & Cowell-Meyers, 2007;Bratton, 2005;Cammisa & Reingold, 2004;Childs & Krook, 2006;Mansbridge, 1999;Osborn, 2014).…”
