Egonomics - The science of designing "menu driven" or thought systems in such a manner as to be intuitive to logical interpretation, especially so as being able to return to the last decision point or to the starting point from any location within the system.
For example, when you are using a "menu" on the telephone, ATM, etc. you want to have the ability to return to the last decision point, or to the beginning of the menu from anywhere within the menu. That would be an example of "good" egonomics.
How ego can influence economics. (My 12th graders came up with this today, during a discussion about the Academy Awards and their effect on the economy.)
When you look at how an Academy Award can affect an actor or technical person or director's career, it is a combo of ego and money; hence, egonomics.
