“…Theories answering this question can roughly be grouped into two macrolevel categories. Some theories focus on bottom-up processes, describing how communication between persons shapes the fate of cultural or political development (e.g., Conway et al, 2009; Conway & Schaller, 2005, 2007; Conway et al, 2006). Other theories focus on top-down processes, describing how preexisting ecological conditions might shape cultural or political milieus in systematic ways (e.g., Kitayama, Conway, Pietromonaco, Park, & Plaut, 2010; Kitayama, Ishii, Imada, Takemura, & Ramaswamy, 2006; Schaller & Murray, 2008; Van de Vliert, 2013a; Welzel, 2013).…”
