New analyses and replication attempts have cast serious doubt on the long-standing “carpentered world” explanation for why people perceive certain visual illusions differently across cultures, forcing scientists to rethink how environment, experience and culture shape vision. Once widely taught as a clear example of cultural influence on perception — the idea that people raised in rectangular, “carpentered” built environments are more susceptible to line-length illusions — the hypothesis now appears overstated, methodologically fragile and unable to account for the full pattern of results seen across global and modern populations. For Thailand this means re-evaluating assumptions used in education, design, public health messaging and cross-cultural psychology research, while urging larger, locally led studies that reflect the country’s urban-rural diversity and rich visual traditions.

A new wave of analyses and replication efforts questions the carpentered world explanation for cross-cultural differences in visual illusions. The idea that people raised in rectilinear, urban environments are more susceptible to line-length illusions is now seen as overstated and methodologically fragile. For Thailand, this prompts a rethinking of assumptions in education, design, public health messaging, and cross-cultural psychology while urging larger, locally led studies that reflect the country’s urban-rural diversity and rich visual traditions.
