This is from Oyserman, D. (2017). Culture three ways: Culture and subcultures within countries. Annual review of psychology, 68, 435-463:
Knowing what is normative or valued in one’s society provides an interpretive lens through
which to understand experiences with others and what is likely or expected in social interchange
(Fiske & Taylor 2013). In this way, core themes influence perception and experience regardless of
whether one personally endorses them (Zou et al. 2009) and whether most people actually endorse
that theme. Therefore, a theme may be perceived as core long after it no longer is, or even if it
never was, core. This has been termed the illusion of universality or pluralistic ignorance (for a
review, see O’Gorman 1986)
