pass phrase search space reducer

The human mind is far less random than we like to think. Common phrases, thoughts, and ideas pop up in patterns and the same associations are made at various times. Furthermore certain emotions and memories are likely to give rise to the same speech patterns.

I propose a comprehensive study of the human mind that uses observation of the way a subject reacts to various stimuli as he goes about his life. These stimuli would include everything from "being bored all day" to "hearing the word fruitcake" to "hearing his father say "how are you".

When a sufficiently large collection of information about how a person speaks, thinks, writes, and types is made it can be used to tremendously reduce the search space for a passphrase.

Also useful as a general study in psychology and the real-world limitations of the human mind.
