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.
