So, which field of study faces the most problems with cheating? Business, according to research by cheating expert Donald McCabe of Rutgers University. A majority of grad students in business—56 percent—acknowledged that they had cheated at least once, compared with 47 percent in other fields. "Some business students have developed a bottom-line mentality," explains McCabe. "Getting the job done is what matters; how you do it is less important."
