I discovered this year that I am WEIRD \u2014 a term utilized by psychologists to refer to the narrow segment of humanity, approximately twelve percent of the global population, whose reactions have subtly represented the entire species in about ninety-six percent of the studies in the psychology journals examined by researchers.<\/p>\n
I had perused years of popular psychology headlines without ever posing the one question that turns out to be crucial: who, precisely, participated in these studies?<\/p>\n
Not \u201chumans,\u201d as the headlines suggested. A very specific type of human, recruited from a very specific type of environment, typically because they were enrolled in an undergraduate course led by the individual conducting the study.<\/p>\n
The acronym that subtly challenges a century of headlines<\/p>\n
WEIRD stands for Western, Educated, Industrialized, Rich, Democratic. It was introduced in 2010 by psychologists Joseph Henrich, Steven Heine, and Ara Norenzayan, in a paper for Behavioral and Brain Sciences that did not shy away from its blunt title: \u201cThe weirdest people in the world?\u201d Their argument was not that Western researchers had been careless. It was that an entire field had spent decades quietly mistaking one small, historically atypical slice of humanity as a representative of the species, and had constructed a science of \u201cthe mind\u201d almost entirely from it.<\/p>\n
The ninety-six percent statistic traces back to an earlier review by psychologist Jeffrey Arnett, who examined six major American psychology journals and determined that the vast majority of published studies \u2014 from a discipline that asserts to explain how people think, in general \u2014 had gathered their human subjects from Western, industrialized nations, predominantly the United States. Henrich\u2019s team took that finding and posed the question that actually changes the perspective: what occurs if the group psychology studies most is also, across a lengthy list of measurable characteristics, the most peculiar one to examine?<\/p>\n
Twelve percent representing everyone else<\/p>\n
That reframing is the aspect that genuinely impacted me. WEIRD populations aren’t a neutral baseline from which other cultures diverge at the edges. On an impressive number of dimensions, they are the outliers \u2014 the exception subtly generalized into the norm. Henrich and his colleagues compiled cross-cultural data indicating that Western subjects are unusually susceptible to certain visual illusions that individuals in other societies hardly notice, exceptionally individualistic in how they view themselves, and particularly inclined toward specific concepts of fairness in economic bargaining scenarios, while being notably analytical rather than relational in their reasoning about causes and effects.<\/p>\n
Psychology spent a century depicting \u201cthe human mind,\u201d predominantly by querying the one demographic least representative of it.<\/p>\n
Some specific examples in the original paper provide details that reshape your understanding of an entire field. The M\u00fcller-Lyer illusion \u2014 two lines of equal length that appear different due to the angled fins at their ends \u2014 is presented in introductory psychology courses as a nearly universal peculiarity of human visual perception. It isn\u2019t. Researchers assessing populations outside industrialized, structured environments, areas lacking many rectangular buildings and right angles that influence visual perception in a particular manner, have found that the illusion scarcely registers for certain groups. The leading explanation \u2014 that it\u2019s a side effect of growing up surrounded by a lot of straight walls \u2014 is now also questioned by researchers revisiting the original data, but the cross-cultural gap in susceptibility is firmly established.<\/p>\n
The same trend is evident in economic games designed to evaluate fairness. In the Ultimatum Game, one player proposes a division of money, which the other can accept or reject; if rejected, both players receive nothing. American undergraduates, the population the game was designed for, consistently punish offers they deem too stingy, even at a loss to themselves \u2014 a discovery documented for years as evidence of an inherent human sense of fairness. Conduct the same game across small-scale societies with varying economic structures, and both the offers made and the offers accepted shift significantly, sometimes in the opposite direction. The \u201cinnate\u201d instinct was, at least partially, a learned one, calibrated to a market economy most of the species has never experienced.<\/p>\n
Coming to realize I fit into that twelve percent \u2014 sufficiently Western-adjacent, educated enough, online enough \u2014 felt more like an uncomfortable examination of everything I had previously considered settled truth from psychology headlines. How much of \u201chumans tend to\u2026\u201d was actually \u201cpeople who read the same few magazines as the researcher tend to\u2026\u201d? I doubt I\u2019ve interpreted a \u201clandmark study finds\u201d headline in the same way since.<\/p>\n
What I intend to do with this now<\/p>\n
I\u2019m not suggesting that anyone should dismiss a century of research, and neither did Henrich, Heine, and Norenzayan \u2014 their argument was not that WEIRD psychology is incorrect, only that it has been severely exaggerated as universal. What has shifted for me is smaller and<\/p>\n","protected":false},"excerpt":{"rendered":"
