Addressing the issue of sharing the data of medical research to the public, author Harlan M. Krumholz persuades his readers that this kind of sharing has many benefits in his article “Give the Data to the People.” He effectively uses diction, concession, and parallelism to construct a coherent argument.

Krumholz begins his article by using well-crafted diction. In describing the move of Johnson&Johnson sharing its clinical trial data, he uses such words and phrases as "an extraordinary donation to society,” and “a reversal of the industry’s traditional tendency” to suggest that J&J has made unprecedented contribution to both the people and the business. He also implies that the original method of keeping clinical research results as secret leaves us with too little useful information by asserting that “the most troubling implications is that full information on a drug’s effects may never be discovered or released.” These intentionally selected words and expressions not only allow the author to lead readers to realize that they were concealed with the facts that they should have known, but also serve to appeal to readers’ emotion, evoking their antipathetic feelings towards the original practice of pharmaceutical companies. This spurred emotional response definitely motivates readers to agree with the author’s stance that the status quo should be changed. In using emotionally laden language, Krumholz adds clout to his argument.

Krumholz also addresses potential difficulties to persuade his readers of supporting medical data sharing. In the paragraph 5 and 8, he acknowledges the dilemma of medical companies sharing their research results, and admits the potential risk of disclosing the data. However, he does not agree with this concession to discredit the data sharing; rather, he is using them to reassure his readers that data sharing is of benefit to America no matter what, because he instantly follows the concession with refutation that “our intent is … to ensure that the data are used in a transparent way and contribute to overall scientific knowledge.” In this way, he is eliminating readers’ possible doubts and boosting their faith in data sharing. By using the concession and refutation, the author further motivates readers to champion his call for this action.

Finally, Krumholz uses parallel structure to further sway his audience into agreeing with him. In his final statement, he claims that “it honors the contributions of the subjects and scientists…It demonstrates that the organization has nothing to hide. And it enables scientists to use the data to learn new ways to help patients.” By repeating identical grammatical structures, Krumholz is creating a dramatic effect to make the sentence memorable so that the point of view being made stays in the audience’s mind. Through the unforgettable sentence, he warps up his ideas that multiple advantages will be achieved if the medical companies choose to share their research data, conveying an optimistic outlook to inspire his audience to stand with him. The skillful use of repetition further adds power to his argument for addressing the issue.

In conclusion, by using carefully chosen words, concession, and parallel structure, the author establishes a well-rounded point, persuading his readers that the pharmaceutical companies should publish their data for the sake of the well-being of the whole society.
