“…In line with this hypothesis, experimental research across many species, from honeybees to parrots to orangutans, has provided evidence that individuals in more resource-rich environments exhibit greater exploratory behaviors (e.g., Damerius et al, 2017; Forss et al, 2015; Katz & Naug, 2015; Mettke-Hofmann et al, 2002). In humans, some studies showed that familial socioeconomic levels or other factors of environmental quality were associated with higher levels of curiosity in kindergarten (Shah et al, 2023; see also: Xu et al, 2023), more creativity in elementary school children (Zhang et al, 2018), and heightened levels of openness in adolescence (Lloyd et al, 2022; see Oh et al, 2023, for longitudinal data; see Menardo et al, 2017, for a negative association between childhood adversity and exploration in a behavioral task). Data from the World Values Survey also demonstrate a strong correlation between a country’s gross domestic product per capita, a proxy for environmental affluence, and the average level of trait openness to change in this country: Individuals in higher gross domestic product societies tend to be more open to change (Korotayev et al, 2019).…”
