Puzzling to see the @TheEconomist offering an analysis of the impact of cousin marriage without considering the recent work in Economics showing the powerful effects of the practice on economic and political outcomes. Let's review. First, the Economist's discussion: economist.com/united-states/…

Is GPT psychologically WEIRD? Using the World Values Survey and other psych measures, we seat GPT within a global perspective. The culturally more distant a place is from the US, the lower the correlation with GPT @MohammadAtari90 @blasi_lang @DorsaAmir GPT falls between Germany and New Zealand...@mmuthukrishna

Anthropologists have long argued that kinship represents the oldest and most fundamental of human institutions. Does kinship--the organization of families--impact global economic outcomes in the modern world? An interdisciplinary and international team of anthropologists and economists take a look: @DumanBRad @JF_Schulz papers.ssrn.com/sol3/papers.cf… @DrNathanNunn @GalorOded @DanielHruschka @mmuthukrishna @aiyanakoka @martinlangcz @CFCamerer @DrDaronAcemoglu @robert_t_boyd @tylercowen

New paper from the Laboratory for Culture, Cognition and Coevolutionary at Harvard @StevenHeine4 @slingerland20 @David_S_Wilson @gophilosophy_ @MicheleJGelfand trebuchet.public.springernature.app/get_content/2e… You can't understand "human" feet, bite, body temperature, hormones, vision, immune systems and much more without understanding the impact of culture. @MGurven @corenapicella

Jump starting a new field: Historical Psychology. Pop the clutch... @slingerland20 @mmuthukrishna @RachelASpicer annualreviews.org/doi/abs/10.114… Psychology must take history seriously and team up with historians and other experts. Things that occurred centuries ago influence how we think, reason and perceive now.

Is the free exchange of diverse views out in the academy? This open letter, from a supposedly learned society, calls for the silencing and demotion of @sapinker based largely on tweets going back a decade.

The letter reads like a parody of academic discourse. They open with a dose of innuendo and guilt by association, but then publicly wash their hands. They dissect a scattering of Pinker’s statements, always confidently asserting the least charitable interpretation.

The WEIRD scale is out in Psychological Science. If you are a psychological scientist and want to generalize your findings beyond Americans, or whichever narrow sliver of humanity you started with, how can you make the best use of your resources? @mmuthukrishna @Adrian_V_Bell Cultural distance from the USA and China using a measure firmly grounded in cultural evolutionary theory. @wgervais

Interesting findings on personality variation across 15 nations by Laajaj et al in @ScienceAdvances. Kudos to the authors. Imho, they show little evidence for the BIG 5 model of personality outside the WEIRD societies. advances.sciencemag.org/content/5/7/ea… However, analyzing a wide range of data with large-samples, they do find 1 dataset that does better in giving them data that matches the USA's BIG-5. It's an online website of mostly young, educated people that must respond in English, German, Dutch or Spanish.

When I discuss my concern that psychologists and behavioral economists rely on a thin and peculiar slice of humanity in order to understand HUMAN psychology, they often reply with the strong intuition that they (but perhaps not others) are studying “basic processes,” etc. To assess how difficult it is to identify these “basic process” without both evolutionary theory and serious cross-cultural research, let’s put aside psychology and focus on physiology and anatomy. Surely, those are “basic.” #WEIRDPeopleProblem

Many psychologists seem very concerned about diversity among their faculty and grad students. But, nearly a decade after the WEIRD People problem was identified as a scientific issue, there's been essentially no change in the diversity of psychology PARTICIPANTS. >90% WEIRD In Psychological Science in 2017, nearly 50% of all samples were American, but NO participants from Africa or Latin America. 6.6% from "Asia", which includes China, India and the entire Middle East. There was NO information on sources for nearly a quarter of the samples! Generic

Proper analyses of Whitehouse et. al.’s data reveals that moralizing god PRECEDE the rise of complex societies, but serious data concerns persist. psyarxiv.com/jwa2n @babeheim @DrQueue @martinlangcz @willismonroe @mmuthukrishna @slingerland20 @RachelASpicer @aiyanakoka To see the issue, first take a look at the data the authors’ analyzed. 1 = moralizing god present, 0 = evidence of no moralizing gods, and NA = Missing data.
