“…Understanding the nature of this shift is critical, as Americans' perceptions of socioeconomic mobility shape the extent to which they trust and act in ways consistent with the prevailing social system, which includes both beneficial and harmful elements (see Browman, Svoboda, et al, 2019). For example, experimental research has found that among adolescents and young adults from lower socioeconomic status (SES) backgrounds, holding weaker mobility beliefs (i.e., believing that their low SES is unlikely to change) reduces persistence and resilience in domains that are promoted as means to upward mobility (i.e., academics; Browman et al, 2017;Browman, Svoboda, et al, 2019;Laurin et al, 2011) and can contribute to poorer psychological well-being (Kraus & Tan, 2015). At the same time, American adults holding weaker perceptions of mobility view their society as being less meritocratic and just, thereby reducing their tendency to rationalise and defend unfair economic and social policies -normally a major barrier to societal change (Day & Fiske, 2017;Newman et al, 2015;Shariff et al, 2016).…”
