A metaphor for a researcher's (or field's) one major, unconscious area of ignorance that systematically skews how they design experiments and interpret data. It's the one big thing they cannot see about their own assumptions—often their cultural, gendered, or economic viewpoint—which acts as a hidden lens distorting everything.
*Example: A 20th-century psychology field dominated by wealthy Western men designing studies on "human" motivation using only male undergraduates as subjects. Their single blind spot bias—assuming their experience was universal—led them to pathologize women and non-Westerners for differing.*
