Episode notes
Numbers Feel Gradual, Not Binary
- Our brains sometimes treat numbers as varying degrees of oddness or evenness rather than strict categories.
- Processing fluency and divisibility (e.g., by 5) help explain why some numbers feel "more even."
Processing Fluency Shapes Number Preference
- Processing fluency influences liking and belief: easier-to-process items feel more positive or true.
- Even numbers are often processed more easily, which may bias preferences toward them.
Parity Gets Gendered Subconsciously
- People sometimes apply gender categories to abstract numbers, with odd numbers often seen as masculine and evens as feminine in U.S. samples.
- These associations are weak, culturally variable, and likely subconscious rather than literal.
