Beyond WEIRD Psychology: Measuring and Mapping Scales of Cultural and Psychological Distance

Summary from Twitter thread:

🚨Now out in Psychological Science! Beyond WEIRD Psychology: Measuring and Mapping Scales of Cultural and Psychological Distance

https://journals.sagepub.com/doi/10.1177/0956797620916782

1/ The world is not WEIRD vs non-WEIRD.

How psychologically and culturally distant is the US from Canada? China from Japan?

2/ CFst is a lens for looking at differences between and within populations. It’s flexible, robust, and theoretically-meaningful.

Issue with existing approaches:
1. Societies are distributions of traits. Mean estimates are misleading. Brazil looks like Turkey on Hofstede:

2. Variance captures some of this (Turkey is culturally tighter than Brazil), but how do you capture nominal traits like political priorities: “give people more to say”, “maintain order in the nation”, “fight rising prices”, or “protect freedom of speech”?3. Genetic distance is a proxy, but can be misleading: Hong Kong is more than an order of magnitude more genetically similar to China than to Britain, but is culturally similar to both due to Britain’s century-long history in Hong Kong.4. Linguistic distance is better, but the resolution is low. Difficult to distinguish the cultures of Australia, Canada, the UK and the US, all of whom speak English.3/ Fst is theoretically meaningful within evolution: measures how genotype frequencies forsubpop differ from expectations if there were random mating over the entire population. i.e. it measures the degree to which the populations can be considered structured and separate.4/ For cultural inheritance, this is directly analogous to between-group differentiation caused by selection, migration, and social learning mechanisms.5/ Cultural FST (CFst) is calculated in the same manner as Genetic FST, but instead of a genome, we use World Values Survey as a “culturome”.
Questions as loci.
Answers as alleles.

CFst can handle continuous, binary, or nominal traits.6/ Because traits tend to cluster within a society, it’s also robust to missing questions or data. You can drop even 50% of data or questions and get very little deviation.

Even if we don’t ask every conceivable question, if you ask a broad range, you’ll get a similar answer.

Note: Traits cluster within, but not necessarily between societies. 7/ We create an American scale (useful as a proxy WEIRD scale) and a Chinese scale as an example.

8/ American scale correlates with cultural dimensions, tightness, values, extraversion and personality variance, and many behavioral measures: blood donations, diplomat parking tickets, corruption perceptions, honesty in the wallet drop study:

Civic honesty around the globeRationalist approaches to economics assume that people value their own interests over the interests of strangers. Cohn et al. wanted to examine the trade-off between material self-interest and more a…https://science.sciencemag.org/content/365/6448/70

Distance…

9/ The Chinese scale is less predictive – why? Two possibilities:

1. WEIRD nations are truly psychological outliers in some objective sense. Plug for @JoHenrich ‘s brilliant new book: amazon.com/WEIRDest-Peopl…

2. Psychological measures have been studied because they are remarkable to WEIRD researchers.

If psychology was dominated by Chinese psychologists, we would see a different set of psychological outcomes covered in textbooks. 10/ Resolving which of these explanations is correct will require greater diversity in both researchers and samples.11/ Final caveats:
1. Similar distance from US / China does not mean cultural similarity. Japan & Norway are similarly distant from US, but are not necessarily similar to each other.

Like Colombia and the UK are similarly geo distant from US but nowhere near each other.

Culture is a large n-dimensional space. 2. The US is relatively homogeneous (note, it’s a loose country, but similarly loose in all regions relative to other large populations). Societies are not homogeneous. They have multivariate distributions of many traits along many dimensions with structure within structure.

There are likely to be cultural differences between not only regions within a country but also ethnicities, religions, socioeconomic class, and other groupings. These are all avenues for future research. 3. We need more data from the Middle East and Africa! We have every reason to suspect the American scale will continue to stretch as we map out these psychological terrae incognitae.These regions (and others like South Pacific) are a treasure trove for the next generation of cultural psychologists. Not just about psychological outcomes, but also questions we ask, and way we organize psychology. What we know is the tip of the iceberg of the human psyche. END I lied.

Beyond WEIRD Psychology: Measuring and Mapping Scales of Cultural and Psychological Distance at University of Economics, Prague, Czechia

I presented some work on measuring cultural distance “Beyond WEIRD Psychology: Measuring and Mapping Scales of Cultural and Psychological Distance” (pre-print) and some in-progress follow ups using the technique at the University of Economics, Prague, Czechia.

I also presented some in progress theoretical and empirical work on “Hunter-gatherer egalitarianism and the evolution of evil eye beliefs”. Part of this work was based on a recent paper published in Nature Human Behaviour, with some context published in Evonomics and ProMarket (pre-print).

Hunter-gatherer egalitarianism and the evolution of evil eye beliefs at University College London (UCL), London, UK

I presented some in progress theoretical and empirical work on “Hunter-gatherer egalitarianism and the evolution of evil eye beliefs” at the Biological Anthropology seminar series at University College London (UCL) in London, UK.

Part of this work was based on a recent paper published in Nature Human Behaviour, with some context published in Evonomics and ProMarket (pre-print) as well as some work on measuring cultural distance (pre-print).

Cultural Evolution and the Measurement of Culture at Monash University, Melbourne, Australia

SPSSI-UK Symposium on “The Current Migration Crisis in Europe” in Cardiff, UK

SPSSI-UK organized a symposium on the Migration Crisis. The symposium was attended by an array of social scientists, but also policy makers, impact officers, and community organizers. I presented some work in progress on “The Paradox of Diversity, Migration, and Cultural Evolution in Europe”. My talk briefly introduced the science of cultural evolution (for a quick intro, see Cultural Evolution), the implications of cultural evolutionary theory for managing the migration crisis, and some results from a new tool I’ve been building to better quantify the size and dimensions of cultural differences.

More on this “Cultural Distance” tool soon.

The outcome of the discussions will also be released by SPSSI-UK as a white paper (in prep).
