Ask any human to choice a number between 0 - 0xFFFFFFFF

Discussion in 'Computer Security' started by Dennis Yurichev, Jan 22, 2007.

  1. Hi.
    Consider some software asking different users for a hexadecimal number
    between 0 - 0xFFFFFFFF.
    Is there any done research in statistical (and psychological) field on
    what numbers used more often and less often, except of obvious numbers
    like 0x11111111, 0x12345678, et cetera.

    Same as for 1 to 10. Very low numbers, very high numbers, very median
    numbers and very regular numbers (wrt patterns) are tried to be avoided.

    The effect is purely psychological.

    At least, it wouldn't make up a good PRNG. =)
