“…However, NCR has also attracted criticism from within and outside the approach. Critics argue that NCR lacks theoretical consistency, employs intervening variables ad hoc, and theorizes in a regressive and degenerative manner (Legro and Moravcsik, 1999; Narizny, 2017; Rathbun, 2008; NR Smith, 2018; Wivel, 2005: 367–370). In response, NCR’s advocates order their intervening variables in two ways: one is to systematize the intervening variables’ likely interaction and influence on state behavior (Ripsman et al, 2016); another is to categorize the different intervening variables, which highlights the differences and richness within NCR (Onea, 2012; Quinn, 2013; Rathbun, 2008; NR Smith, 2018; Taliaferro, 2000; Wivel, 2005).…”
