Research and design decisions heavily influenced by participants from Western, Educated, Industrialized, Rich, and Democratic (WEIRD) societies may not translate effectively to diverse global user bases. This user-centred design research insight is drawn from a 2023 study published in Cambridge University Press eBooks. Using Literature review and critical analysis of research methodologies., researchers explored how this design variable affects real-world outcomes. The key design takeaway: Actively diversify user research to include participants from a wide range of cultural, economic, and societal backgrounds to ensure designs are globally relevant and truly user-centered.
Design decisions based on WEIRD participant pools limit global relevance.

Key Findings
- 01Psychology's reliance on WEIRD participants is a significant limitation.
- 02This bias extends beyond participant demographics to theoretical commitments and methodological assumptions.
- 03The current structure of psychological research is fundamentally WEIRD, hindering its relevance to all humanity.
Application
Design takeaway
Actively diversify user research to include participants from a wide range of cultural, economic, and societal backgrounds to ensure designs are globally relevant and truly user-centered.
How to apply
When planning user research for a new product, explicitly identify and recruit participants from regions and demographics outside of typical Western, Educated, Industrialized, Rich, and Democratic (WEIRD) contexts.
Project actions
- 01When conducting user research, consider the diversity of your potential user base and recruit participants accordingly.
- 02Be critical of existing research you cite; question whether the participants in those studies represent your target audience.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Provides a critical lens for evaluating the universality of psychological findings.
- +Highlights the need for greater diversity in research participant pools.
Limitations
It can be challenging and costly to recruit truly representative samples from diverse global populations for user research.
Reliability & validity
The validity of the critique rests on the extensive review of psychological literature. Reliability is enhanced by the consistent pattern of findings across numerous studies analyzed.
Think critically
How might a design project that exclusively uses WEIRD participants inadvertently create barriers or exclude users from non-WEIRD backgrounds, and what are the ethical implications of such exclusion?
Design Principles
"Global user-centeredness requires diverse research participation."
Designers aiming for universal appeal or specific market penetration must recognize that user behaviors, preferences, and cognitive processes can vary significantly across cultural and socio-economic contexts. Ignoring this can lead to products that are unusable, undesirable, or even offensive to large segments of the potential market.
What This Means for Your Design
If you only ask people from one type of background (like Western, educated, rich countries) what they like or how they use things, your design might not work for people from different backgrounds.

Paragraph starter
The foundational research for this design project acknowledges a significant challenge in user-centered design: the pervasive reliance on participants from Western, Educated, Industrialized, Rich, and Democratic (WEIRD) societies. This 'WEIRD problem' suggests that findings from such limited participant pools may not accurately reflect the needs, behaviors, or preferences of a global user base. To ensure the design's relevance and effectiveness across diverse markets, this project prioritized recruiting participants from a wide array of cultural, socio-economic, and geographical backgrounds, moving beyond a narrow, potentially biased understanding of user needs.
