Episode notes
Binary Bias Makes Continuous Things Look All Or Nothing
- Human minds systematically binarize continuous data, creating a 'binary bias' that distorts judgments and exaggerates extremes.
- Angela Duckworth cites the Psych Science paper The Binary Bias and argues action demands often push us to compress continua into yes/no choices.
Action Needs Push Us Toward Yes Or No Choices
- One reason we binarize is that decisions to act are often categorical (you either treat a patient or you don't), so cognition compresses continua into actionable categories.
- Duckworth and Stephen use medical diagnosis and turning decisions as examples showing how action needs drive categorization.
Four Harms Of Rigid Categorical Thinking
- Categorical thinking risks compressing within-category variation, inflating between-category differences, enabling discrimination, and fossilizing arbitrary structures.
- Stephen reads Harvard Business Review's four dangers of categorical thinking to illustrate societal harms.
