We evaluated scientists' abilities to process two writing styles, active and nominal in comprehension and reading speed, and determined their preferences for these styles. International scientists (with English as a first, second, or third language) were tested. Results show scientists comprehend nominal style as well as active style but process nominal style more slowly. Scientists with lower levels of English experience have proportionately greater difficulty processing nominal style than active style. Scientists prefer active writing to nominal writing and rate scientists who write actively higher than those who write nominally. Scientists should use more active style and technical editors should apply a heavy hand to nominal style.
