You're suppressing the knowledge of how little time it takes to encounter 10,000 numbers and how long you will remember a bunch of digits that seem meaningful.

You're suppressing the knowledge of how little time it takes to encounter 10,000 numbers and how long you will remember a bunch of digits that seem meaningful. And how quickly the possibilities multiply when you include everyone you're in contact with that might tell you about something that happened to them. We're not arguing about one four digit number. Nobody who is paranoid about that is paranoid about just that. Doing a statistical analysis of uses of that number might be instructive if you're really obsessed with it, but it's not the point. I see 666 and 1337 a lot. https://en.wikipedia.org/wiki/Strong_Law_of_Small_Numbers https://en.wikipedia.org/wiki/Strong_Law_of_Small_Numbers
