All In The Mind
Claims about human psychology and behaviour in top international journals are largely based on the WEIRDest people in the world. People from Western Educated Industrialised Rich Democratic - or WEIRD - societies are widely used as research subjects, but the assumption that they represent a universal human population may be vastly wrong, and skew psychological research. More cultural psychology could be the answer.

WEIRD Minds: How Culture Skews Psychology Research
Episode Overview
- Most psychological research relies heavily on participants from Western, Educated, Industrialised, Rich and Democratic societies, which can distort claims about human behaviour.
- WEIRD populations often sit at the extreme end of global psychological variation in traits such as individualism, trust of strangers, and focus on intentions in moral judgement.
- Visual perception and memory show clear cultural shaping, from optical illusions influenced by carpentered corners to how parents in different cultures share and frame children’s memories.
- Analytic thinkers tend to break continuous activities into many small parts, while holistic thinkers perceive interconnected events, affecting how everyday tasks are understood.
- Researchers are urged to clarify whether and how their findings can extend beyond WEIRD samples and to take culture seriously if they aim to understand human behaviour more fully.
“So the culture is like the water. So we may easily take it for granted without being aware that it's influencing our behaviour.”
Curious about why so much psychology research focuses on a pretty narrow slice of humanity? This episode of All In The Mind takes that question seriously and asks what it means for how we understand the mind. Anthropologist Professor Joe Henrich from Harvard lays out how he and his colleagues coined the term WEIRD — Western, Educated, Industrialised, Rich and Democratic — after realising that around 96% of participants in psychology experiments come from these societies.
He explains that these groups often sit at the extreme end of global psychological variation, yet their responses are regularly treated as universal. From moral judgement based heavily on intentions to strong individualism and analytic thinking, Henrich shows how WEIRD traits can skew what textbooks present as "human" psychology. You’ll also hear from Professor Qi (Chi) Wang from Cornell University, who brings a cultural psychology lens to memory and child development.
Using the vivid image that "culture is like the water" a fish swims in, she talks about how parents in European American families often place the child as the "leading actor" in shared memories, while East Asian parents highlight relationships and other people’s roles. These early conversations help shape how children later remember their own lives. The episode gets practical too, with everyday examples such as making coffee or doing the dishes.
Wang’s research compares how Indians and Americans break these activities into smaller events, showing how holistic versus analytic styles affect how people see routine tasks. Immigration and acculturation are woven into the discussion, as Henrich describes how cultural echoes of parents’ homelands can still be detected in second-generation immigrants. If you’ve ever assumed psychology findings apply to everyone, this conversation might prompt you to ask: whose minds are we really learning about, and what cultures are quietly shaping those results?
