==Human generation of random quantities==
Humans generally do poorly at generating random quantities. Magicians, professional gamblers and con artists depend on the predictability of human behavior. In [[World War II]] German code clerks were instructed to select three letters at random to be the initial rotor setting for each [[Enigma machine]] message. Instead some chose predictable values like their own or a girlfriend's initials, greatly aiding Allied breaking of these encryption systems. Another example is the often predictable ways computer users choose passwords (see [[password cracking]]).

Nevertheless, in the specific case of playing [[mixed strategy]] games, use of human gameplay [[entropy]] for randomness generation was studied by Ran Halprin and [[Moni Naor]].<ref>{{cite web | url=https://cups.cs.cmu.edu/soups/2009/proceedings/a12-halprin.pdf | title=Games for Extracting Randomness |author1=Halprin, Ran |author2=Naor, Moni }}</ref>
