CONCEPT
Stereotypes as Cognitive Architecture
Pre-formed categories and templates of interpretation that allow the mind to sort, filter, and organize information—not optional biases but the structural prerequisite of thought itself, determining in advance what counts as evidence and rendering disconfirming information actively invisible.
Lippmann invented the modern psychological meaning of 'stereotype' in Public Opinion (1922), transforming a printing term into a foundational concept of cognitive science. His argument was radical: stereotypes are not errors that better thinking eliminates—they are the scaffolding that makes thinking possible. Without pre-formed categories, the mind would drown in undifferentiated data. Every face would be unfamiliar, every situation unprecedented. The cost is that the template shapes perception—the category determines what counts as evidence, and what does not fit the template becomes structurally unperceivable. The AI camps of 2025 were stereotypes in this technical sense: cognitive architectures determining in advance what the AI moment would be allowed to mean. The accelerationist template filtered for capability demonstrations and productivity gains while rendering invisible the Berkeley burnout data. The elegist template filtered for depth erosion and addiction testimonials while rendering invisible the genuine capability expansion.
