The problem is, we already have replications being done by Indian and Chinese scientists and... they're not very good. Here's one: "Local Literature Bias in Genetic Epidemiology: An Empirical Evaluation of the Chinese Literature", 2005:
"We targeted 13 gene-disease associations, each already assessed by meta-analyses, including at least 15 non-Chinese studies. We searched the Chinese Journal Full-Text Database for additional Chinese studies on the same topics. We identified 161 Chinese studies on 12 of these gene-disease associations; only 20 were PubMed-indexed (seven English full-text). Many studies (14–35 per topic) were available for six topics, covering diseases common in China. With one exception, the first Chinese study appeared with a time lag (2–21 y) after the first non-Chinese study on the topic. Chinese studies showed significantly more prominent genetic effects than non-Chinese studies, and 48% were statistically significant per se, despite their smaller sample size (median sample size 146 versus 268, p < 0.001). The largest genetic effects were often seen in PubMed-indexed Chinese studies (65% statistically significant per se). Non-Chinese studies of Asian-descent populations (27% significant per se) also tended to show somewhat more prominent genetic effects than studies of non-Asian descent (17% significant per se)."
Most of the research on cognitive biases and other psychological phenomena that we draw on here is based on samples of students at US universities. To what extent are we uncovering human universals, and to what extent facts about these WEIRD (Western, Educated, Industrialized, Rich, and Democratic) sample sources? A paper in press in Behavioural and Brain Sciences the evidence from studies that reach outside this group and highlights the many instances in which US students are outliers for many crucial studies in behavioural economics.

Broad claims about human psychology and behavior based on narrow samples from Western societies are regularly published in leading journals. Are such species-generalizing claims justified? This review suggests not only that substantial variability in experimental results emerges across populations in basic domains, but that standard subjects are in fact rather unusual compared with the rest of the species - frequent outliers. The domains reviewed include visual perception, fairness, categorization, spatial cognition, memory, moral reasoning and self‐concepts. This review (1) indicates caution in addressing questions of human nature based on this thin slice of humanity, and (2) suggests that understanding human psychology will require tapping broader subject pools. We close by proposing ways to address these challenges.
