Humans Generating Random Numbers

Generating random numbers as a human is fun. But easily exploitable. We keep doing non-random things. Khanacademy even has a lovely video about this.

In technical terms, a human is a “weak entropy source”. Which means that “randomness extractors” can be used. A simple one is the Von Neumann Extractor. Thank you to eleanor for pointing me at that.

This gives us a simple algorithm, where you think of a number, convert it to binary and use the extractor on the bit streams.

In binary that is
