Numerical Quote by Stanislas Dehaene
““An innate sense of approximate numerical quantities may well be embedded in our genes; but when faced with exact symbolic calculation, we lack proper resources. Our brain has to tinker with alternate circuits in order to make up for the lack of a cerebral organ specifically designed for calculation. This tinkering takes a heavy toll. Loss of speed, increased concentration, and frequent errors illuminate the shakiness of the mechanisms...””
About This Quote
Source Book: The Number Sense, Stanislas Dehaene, 1997
Human brains are not evolutionarily optimized for precise arithmetic, so we repurpose other neural circuits, causing slower, error‑prone calculation.
In simple terms: Our brains are not built for exact math, so we improvise and make mistakes.
Key Takeaway
Accept limits, use tools for exact work.
