When two major, reinforcing areas of ignorance coexist, creating a powerful, self-validating distortion. For example, a field might be blind to both its cultural bias and its commercial funding influences. Each blind spot protects the other; questioning one is dismissed by appealing to the rigor implied by the other.
Example: Nutrition science historically blind to both cultural dietary diversity and the massive funding influence of the food industry. This double blind spot bias produced "universal" dietary guidelines that reflected Western habits and industry interests, while dismissing other diets as unscientific.

This bias ignores how the study's fundamental design, question framing, population selection, and statistical analysis are all loaded with human choices and cultural values before the first pill is blinded.
*Example: Citing a double-blind study "proving" a new antidepressant works, while ignoring that the study only measured a narrow, questionnaire-defined "depression" over 8 weeks in a hand-picked cohort, excluding people with complex comorbidities. The double-blind bias mistakes a specific, constructed result for universal, contextless truth.*
