Skinner (1948) imagined a world in which the natural science of behavior would be applied to free us from coercive cultural practices, and its applications could contribute to intentional cultural design to achieve that end. He elaborated on these ideas in several subsequent, nonfictional works (e.g., Skinner 1953Skinner , 1971Skinner , 1974Skinner , 1981Skinner , 1987. These works provided the conceptual and theoretical bases for many behavior scientists to begin to consider the evolution of cultures and the selection of cultural practices (e.g., Baum 2005;Couto and Sandaker 2016;Glenn 2004;Houmanfar et al. 2010;Malott and Glenn 2006) and to actively challenge behavior scientists to work toward mitigating some of the world's most pressing challenges (e.g., Biglan 2015Biglan , 2016Biglan and Embry 2013;Dixon et al. 2018;Mattaini and Aspholm 2016;Wilson et al. 2014).Cultural and behavioral systems science brings together a broad range of behavior scientists with different influences, specializations, and focus areas from within and outside of behavior science. Two fairly well-known examples of such work include Brethower's (1972) Total Performance System and Glenn's (1986) conceptualization of the metacontingency (see also Glenn et al. 2016 for the most recently agreed upon terms and definitions). Brethower's work was strongly influenced by general system(s) theory (e.g., von Bertalanffy 1968; cf. Brethower 2008) and is broadly applied by behavior scientists who consider their specialization behavioral systems analysis or organizational behavior management (e.g. McGee and Crowley-Koch, this issue). Glenn's seminal contributions to cultural and behavioral systems science were inspired by anthropology (i.e., cultural materialism;Harris 1964Harris , 1979 see also Glenn 1988) and biology (cf., Glenn 1991;Hull et al. 2001) and is very influential with those behavior scientists who describe their specializations as cultural systems analysis and/ or cultural selection. Even though many working in cultural and behavioral systems science identify with a specific lineage or claim a particular specialization, many also
