认知差距：大脑为何难以理解亿万富豪的财富
Numbers like 'a billion dollars' are thrown around so casually that they feel almost ordinary. Yet our brains struggle to grasp their true scale. Take time as an example: a million seconds is about eleven days, but a billion seconds is over thirty-one years. This vast difference seems less dramatic to us because the human brain naturally represents numbers in a compressed, logarithmic fashion.
Cognitive scientists have long studied this phenomenon, and their experiments reveal a consistent pattern. When volunteers place numbers on a line, most space small numbers widely but crowd large numbers together. This reflects a logarithmic scale, where each step multiplies rather than adds. The finding suggests that our mental number line is naturally curved, compressing the gap between huge quantities.
