Hollywood rationality is a popular stereotype of what rationality is about. It presents "rationalists" as word-obsessed, floating in endless verbal space disconnected from reality, reciting figures to more decimal places than are necessary, or speaking in a dull monotone. Hollywood rationalists also tend to either not have strong (or any) emotions. When they do, they often do not express them. Needless to say, this has nothing to do with actual rationality.
